In this article we will look at how to correctly determine the optimal width of a website for a desktop monitor and mobile devices, where you can find out the latest statistics on popular screen resolutions, how to check the display of your website at different resolutions and identify possible problems.

• What are the website size formats for layout?
• What are the options for creating a page for different monitors and resolutions ? Fixed layout
• Rubber layout without restrictions
• Rubber layout with specified minimum and maximum width
• Adaptive layout

When developing a design for adaptive layout, you need to take into account the size of the devices on which most often be viewed. Depending on your topic, these could be: smartphones, tablets, laptops, desktops, or even large TVs with a diagonal of up to 98 inches.

And if there are no problems for the user, then the developer already faces certain difficulties, because on each of the screens the site must be beautiful, convenient and functional.

Therefore, when developing a layout, we want the space to be used wisely and at the same time:

• When viewing the site on widescreen screens, there was no huge empty space on the sides, the images remained high quality, and the text was easy to read.
• The site remained usable on a small screen, with no horizontal scroll bar or hidden elements appearing.

But first, let’s figure out what width the HTML page should be.

How to calculate the dimensions yourself?

Width

When calculating, take the smallest indicator so that the walls of the product can fit between the walls. Even a difference of 2–3 mm makes a difference, so many measurements are taken. From the resulting figure, subtract approximately 30 mm on each side so that the cabinet fits into the opening.

There are 3 indicators taken into account here:

• Wall slope . Maximum measurements are taken, especially if the walls are not level enough.
• Number of measurement points . If you take more measurements at different heights, then fewer millimeters will need to be allocated for possible error.
• Construction . If the model is built-in, then everything is simple, but for errors in an autonomous design, you will need to take a larger distance.

Height

To calculate the height, measure the distance from the floor to the ceiling at different levels. Then the smallest indicator and possible error are calculated. Usually this is 10 cm, if the distance itself is no more than 250 cm, and the depth is up to 70 cm. The height indicators will subsequently affect the installation.

Depth

Any closet has useful space (where things will be stored) and useless space (it is allocated to the sliding door system, usually about 10 cm). It is important to consider here:

• Maximum depth taking into account the characteristics of the room. If you leave only 60 cm for it and subtract 10 cm from here for the error, this may not be enough.
• The corresponding functionality, which approximately coincides with the dimensions and capabilities of the usable space. For example, to place a classic clothes rail in a closet you need at least 50 cm.

Length

As already mentioned, in mathematics, length, height, width are three spatial dimensions. Moreover, if width is a linear dimension in the transverse direction, then length is in the longitudinal direction. Considering it as a quantity of physics, one can understand that this word means a numerical characteristic of the length of lines.

In English this term is called length. It is because of this that this value is denoted by the capital or lowercase initial letter of the word - “L”. Like width, length is measured in meters or their multiples (multiples).

Width

As mentioned above, in mathematics the quantity in question is one of the three spatial dimensions of any object, provided that its measurements are made in the transverse direction. So what is width famous for? It is designated by the letter “B”. This is known all over the world. Moreover, according to GOST, it is permissible to use both capital and lowercase Latin letters. The question often arises as to why this particular letter was chosen. After all, the abbreviation is usually made according to the first letter of the Latin, Greek or English name of the quantity. In this case, the width in English will look like “width”.

Probably the point here is that this parameter was initially most widely used in geometry. In this science, when describing figures, length, width, height are often denoted by the letters “a”, “b”, “c”. According to this tradition, when choosing, the letter "B" (or "b") was borrowed from the SI system (although symbols other than geometric ones began to be used for the other two dimensions).

Most believe that this was done so as not to confuse width (designated with the letter "B"/"b") with weight. The fact is that the latter is sometimes referred to as “W” (short for the English name weight), although the use of other letters (“G” and “P”) is also acceptable. According to international standards of the SI system, width is measured in meters or multiples (multiples) of their units. It is worth noting that in geometry it is sometimes also acceptable to use “w” to denote width, but in physics and other exact sciences such a designation is usually not used.

BASIC POINTS

1.1. A certain quantity is denoted by a letter of the Latin or Greek alphabet without indices or with indices that serve to clarify the various characteristics of this quantity.

1.2. Uppercase and lowercase letters “O, o” of the Latin alphabet should not be used in notation. The letters of the Greek alphabet should be taken according to the table. 1.

1.3. The letter designations of the required quantities not given in this CMEA standard are established according to the principle indicated in table. 2.

Force, the product of force and length, length to a power not equal to unity

Uppercase Latin alphabet

Length, the ratio of length to time to some extent, the ratio of effort to a unit of length or area

Lowercase Latin alphabet

Lowercase Greek alphabet

1.4. Indices are divided into digital and alphabetic. Letter ones are further divided into one-, two- and three-letter ones. Arabic numerals are used to denote digital indices, and letters of the Latin alphabet are used to denote alphabetic indices.

1.5. Digital indices are used to express the serial number of a given designation.

1.6. Single-letter indices are used to designate coordinate axes, location, type of material, stress state, effective load and other characteristics.

1.7. Two-letter and three-letter indices are used when the use of one-letter indices may lead to ambiguities. They are separated from single-letter indices by commas.

1.8. The indices are located on the right side of the letters at the bottom. When typing on a typewriter, the letter and index can be printed on the same line.

1.9. If this standard does not contain the required index, it should be established from lowercase letters of the Latin alphabet.

1.10. A designation expressing a geometric quantity may be supplemented with a vertical stroke on the right if it is necessary to indicate that the compressed part of a section or element is meant.

How do you write length width height?

length with the letter l, if we are talking about one straight line: a pendulum, a lever, a segment, a straight line. But if we are talking about a geometric figure, for example, a rectangle, then A is used, height or depth is h, width is B.

In what order are the overall dimensions indicated?

Overall dimensions of the product length 1500 mm width 1200 mm height 2500 mm, there is a doubt that it may be necessary to write 1500×1200×2500, as is written in many product forms, but here is the correct alternation in GOST (length×width×height or width×length×height or…)

Which comes first, width or height?

Let the length always come first, then the width and height. This will make it easier for the buyer to get used to the format. The format “1450×975×455 mm” is quite clear even without clarification, because there is a picture next to it. For many items, not only overall dimensions are important.

How to correctly indicate the size of a painting?

For works of art, dimensions are indicated according to the stretcher or board (height, width). For works of graphics, double size (height, width) is indicated - sheet and image. This was taught in school: the X and Y axes are always the width first, and then the height.

How are bag sizes indicated?

Height and width of the bag: height is measured from the highest point to the bottom edge (excluding the handle), width is measured between the two extreme points horizontally. Bag depth: measured from the side at its widest point. Handle length: measured from one end to the other using a flexible measuring tape.

How to determine what is the length of an object and what is the width?

Width is the extent between two points of the plane that, unlike length, lie at the shortest distance from each other. That is, length is the largest size of an object, and width is the smallest. It must be remembered that width is always measured transversely to the length.

How are length and width defined?

The corresponding capital letters can also be used for designations; in the literature, the combination L, B, H is often found (L - length, B - width, H - height). The same letters are also used in physics to denote the length, width, and height of objects.

What are the sizes of the paintings?

Standard sizes of paintings, posters and posters (European series, cm): 18x24, 24x30, 30x40, 35x50, 40x50, 50x60, 50x70, 50x100, 60x70, 60x80, 60x90, 90x120. Standard formats of paintings and photographs (cm): 21x29.7 (A4 format), 29.7x42 (A3 format), 32.9x48.3 (A3+), 42x59.4 (A2 format).

What letter indicates width?

As mentioned above, in mathematics the quantity in question is one of the three spatial dimensions of any object, provided that its measurements are made in the transverse direction. So what is width famous for? It is designated by the letter “B”.

What letter represents height?

The corresponding capital letters can also be used for designations; in the literature, the combination L, B, H is often found (L - length, B - width, H - height). The same letters are also used in physics to denote the length, width, and height of objects.

How are sizes written correctly?

And you must first write the length (horizontally X), then the width (vertically Y), then the depth (along the Z axis). Width Height Length (aka Depth, aka Thickness) are the same XYZ.

How to determine the dimensions of furniture?

Dimensions are indicated in millimeters (Fig. 1): – width, depth, height – when describing storage furniture and seating furniture; – width, length, height – when describing furniture for lying down and free-standing tables.

How are clothing sizes written?

Explanation of designations (icons on clothing labels): “XS” (eXtra small – very small), “S” (small – small), “M” (medium – medium), “L” (large – large size), “XL” "(eXtra Large - very large), "XXL" (eXtra eXtra Large - super-large), "XXXL" and so on (more details in the table).

Advantages and disadvantages of asbestos cement sheets

Asbestos cement sheets have earned their continued popularity due to a wide range of advantages. Let's mention just a few of them.

• This is a fairly strong and durable material.
• The presence of an open flame does not pose a threat, it is absolutely fireproof. Moreover, even when located in the source of fire, it does not emit harmful substances.
• Resistant to sudden temperature changes. Pressed samples are able to withstand up to 50 freeze/thaw cycles.
• High maintainability of the roof: it is quite simple to repair it by installing a patch or replacing entire sheets.
• The material is not threatened by such negative phenomena as rotting and corrosion; it is easy to process using the simplest tools.
• The installation of a roof with standard slate sheet sizes is quite simple, it allows you to reduce installation time and save on the professionalism of roofers.

• insufficiently high bending strength and mechanical impact;
• relatively high level of specific gravity - about 20 kg/sq. m;
• the problem of moss formation, which negatively affects the strength of the profile and its visual appeal.

Dimensions of a material object

Since material objects are primarily processed in physical space (objects take up space on the conveyors that transport them), an important aspect for obtaining valid simulation results is the size of material objects. The size of each material object is specified by three dimensions (length, width, height). By default, the dimensions are set to 1 meter.

Setting the dimensions of material objects

The dimensions of non-standard material objects are specified in the Dimensions and movement

properties of a non-standard type agent.

If there is no need for custom material objects, the default size of material objects will be 1*1*1 meters.

The dimensions of material objects (of any type: default and non-standard) can be changed in one of the following ways (new size values ​​override previously set values ​​in the properties of the non-standard type):

Generating material objects of non-standard size

Material objects are usually generated by the Source

Process modeling libraries.
The dimensions of a material object can be set directly during its creation by changing the values ​​of the necessary parameters in the properties of the corresponding Source

Cabinet filling options

The filling of the bedroom closet directly depends on the preferences of the apartment owner. This also applies to the design of the facade. Today there is a wide range of furniture available, not to mention custom-made designs. The internal content directly depends on the design features of the product. Details are selected to ensure convenient use of this interior element.

With two doors

This model is the most popular option for use in the bedroom and dressing room. It is very convenient and easy to use. The interior space is divided into two sections, which are connected at the top by a mezzanine. Options for organizing useful volume:

1. In the first section, a hanger bar is installed. If desired, furniture can be equipped with roll-out baskets for storing knitwear or shoes. On the other side, shelves and drawers are installed.
2. In the second option, the first compartment in the lower part is equipped with a shelf, which is used to store various things and objects. The rest of the space is organized according to the previous scheme.
3. If short items are stored on the hanger, the section can be divided into two compartments by a horizontal shelf. It is also possible to install shelves below the bar.

There are quite a lot of variations in the organization of internal space. When choosing, you should consider your needs and preferences. For the fair sex, the ideal option would be to install drawers with divisions for storing various small items and cosmetics.

wardrobe with two doors

With three doors

Unlike the previous option, this option has three compartments, which significantly increases its functionality. You can distribute the internal space in several ways:

1. The first compartment contains a rod and several shelves or drawers below. The second part is equipped with shelves and drawers. As for the third compartment, it can be divided by a horizontal shelf. This will allow you to organize a place to store bulky items and items.
2. The first compartment consists of two rods, which are located one above the other. The second is a bar with one or more shelves underneath it. In the third compartment, shelves or drawers are installed. If you wish, you can get by with one element, or create an original combination.
3. In the third case, all sections are divided by horizontal shelves. The upper halves contain drawers, shelves and a hanging rod. The lower compartments are ideal for storing bulky items.

The arrangement of internal parts can be varied. The main thing is that the furniture is functional, and the filling of the wardrobes is convenient to use.

Corner design

Installing corner furniture allows you to make the most of the space in the room. A product of this configuration has its own design features. If you organize the internal space correctly, the capacity will be an order of magnitude higher than standard models. This is especially true for the use of corner dead zones. The layout might look something like this:

1. Clothes hangers are installed in the middle. On the sides there are shelves and drawers. If desired, the outer side of the side walls can be equipped with original shaped shelves for storing various decorative items.
2. On one side, long, deep shelves are made. On the other side there are two compartments with shelves. Below there is space left for heavy and bulky items.
3. In the middle, rods with hangers are installed one above the other. There are shelves and drawers on the sides.

In the case of corner furniture, the main thing is to properly organize the arrangement of the wardrobe. This will allow you to use it as efficiently as possible for storing various things and items.

Corner wardrobe

Radius cabinet

The peculiarity of such furniture lies in the original curved doors. This is taken into account when making shelves. They must match the shape of the doors. The structure itself can be concave, convex or wavy.

Despite their appearance, quite large items can be hidden behind the doors. Some models are equipped with pull-out cabinets and dressing tables with a mirror. Therefore, tonis not only look original, but are also very roomy.

Radius wardrobe

Built-in wardrobe

The peculiarity is that the space from floor to ceiling is used at the discretion of the household. In a niche you can install not only shelves and hangers for storing various things. Modular inserts are very popular. So, in the built-in closet you can organize space for a computer or TV. In this case, there are a lot of options. Therefore, you will need to think seriously about organizing the internal space.

Factors taken into account when designing steps

There are not many components in a building structure, but careful and competent calculation of parameters is important:

• march width;
• width of steps;
• the angle at which the steps are inclined;
• step height.

The layout of the building directly affects the shape of the staircase. The width of the opening, span and length of steps will depend on this. The standard (usable) width is 1 m. In such an area, two people can pass each other, and there is enough space to carry bulky loads.

Flights of stairs for apartment buildings should not be made less than 80 cm, in two-story buildings - at least 90 cm. In high-rise buildings this parameter is 105 cm, in public buildings - 135 cm. The maximum size of flights is allowed up to 140 cm in residential buildings, up to 240 cm - in public. For each individual case, the indicators will be different, which means that you need to take into account all the features of the room.

The steps of the spiral staircase are much narrower; there are no flights in it. The structure is necessary solely for climbing to the upper floor and has no other utilitarian functions. This model saves space and serves as an original decor for the room.

Choosing the optimal size of premises in a residential building: selecting the aspect ratio

Depending on the purpose and local conditions, the aspect ratio of the rooms may be different, but, in general, there are optimal values ​​that are most convenient for living, perception, uniform lighting, heating and furniture placement.

Selection of the optimal size of premises in a residential building

Shape of premises (rooms)

In residential buildings, premises (rooms) are usually rectangular or square in shape. Premises with oval, round shapes and shapes with smooth lines are not rational to use in budget class residential buildings; such shapes are accepted in large luxury class houses.

Thickness

Most of us remember school mathematics lessons. Even then, teachers told us that it is customary to use the Latin letter “s” to denote a quantity such as area. However, according to generally accepted standards, a completely different parameter is written in drawings in this way - thickness.

Why is that? It is known that in the case of height, width, length, the designation by letters could be explained by their writing or tradition. It’s just that thickness in English looks like “thickness”, and in Latin it looks like “crassities”. It is also not clear why, unlike other quantities, thickness can only be indicated in lowercase letters. The notation "s" is also used to describe the thickness of pages, walls, ribs, etc.

Marking of door products

Since a very large number of companies are engaged in the manufacture of doors, confusion often occurs with the markings. There are situations when completely identical designs, made using the same technology, not only have different names (this is still quite acceptable), but also have different markings. However, for most models, general standards apply.

GOST 6629-88 is responsible for the parameters of interior wooden doors for public or residential buildings.

There is the following marking for it:

• Name of GOST;
• Height in decimeters;
• The width of the door together with the door is in decimeters;
• The letter “P” says that this is a panel, and the sign “D” indicates that it is prefabricated;
• “O” means that the door is glazed, and the sign “K” means that the door swings.

Additionally, there are symbols that may indicate that the product is left-handed (L), has a threshold (R) and is overlaid (H). Also, each factory can set its own unique codes, providing their decoding.

Classification is carried out in several directions and here, first of all, it is taken into account where the door will be located: inside or outside (interior or exterior). Next, the material of the product is taken into account. Doors are made of wood, steel, glass and combinations. It is indicated that the canvas is solid or glazed. And finally, the number of doors and what they are are taken into account. There are single-field and double-field designs. There are also one and a half. Each model is given an official name.

What standard defines the letter designation of length, width, height, area and other quantities?

As mentioned above, so that there is no misunderstanding when reading the drawing, representatives of different nations have adopted common standards for letter designation. In other words, if you are in doubt about the interpretation of a particular abbreviation, look at GOSTs. This way you will learn how to correctly indicate height, width, length, diameter, radius, and so on.

For the Russian Federation, such a regulatory document is GOST 2.321-84. It was introduced back in March 1984 (during the times of the USSR), to replace the outdated GOST 3452-59.

Length

- a physical quantity, a numerical characteristic of the length of lines.

In most measurement systems, the unit of length is one of the basic

units of measurement through which others are determined ( derivatives

) units. In the International System of Units (SI), the unit of length is the meter.

In a narrow sense, length is understood as the linear dimension of an object in the longitudinal direction (usually this is the direction of the largest dimension), that is, the distance between its two most distant points, measured horizontally, in contrast to height, which is measured in the vertical direction, as well as width

or thickness

, which are measured across the object (at right angles to the length).

In physics, the term "length" is usually used as a synonym for "distance" and is denoted by L or l from it. l

änge (length). Length dimension symbol - dim l = L

. Among other spatial quantities, length is a unit-dimensional quantity, while area is two-dimensional, volume is three-dimensional.

Quantities

Area, length, width, height and other designations of a similar nature are not only physical, but also mathematical quantities.

Their single letter designation (used by all countries) was established in the mid-twentieth century by the International System of Units (SI) and is still used to this day. It is for this reason that all such parameters are indicated in Latin, and not in Cyrillic letters or Arabic script. In order not to create certain difficulties, when developing design documentation standards in most modern countries, it was decided to use almost the same conventions that are used in physics or geometry.

Any school graduate remembers that depending on whether a two-dimensional or three-dimensional figure (product) is depicted in the drawing, it has a set of basic parameters. If there are two dimensions, these are width and length, if there are three, height is also added.

So, first, let's find out how to correctly indicate length, width, height in the drawings.

Have you decided to purchase a cabinet measuring 600x400x500? What do the first, second and third overall dimensions mean? How to determine the size of a pine bed or a metal single bed correctly? Furniture dimensions vary. Sometimes you can find designations without markings (SHGV). How to correctly indicate the dimensions of furniture?

Units of length edit edit code

Metric system edit edit code

The metric system is considered the most convenient of all those invented because of its simplicity. The metric system is based on the unit of measurement meter. All other units of measurement are multiples of powers of ten from a meter (for example, a kilometer is 10³ meters, etc.), which makes calculations easier. Until 1960, the meter had a special standard, now stored at the International Bureau of Weights and Measures, located in the city of Sèvres (a suburb of Paris, France). Today, by definition, a meter is equal to the distance that light travels in a vacuum in 1/299,792,458 of a second.

British American system edit edit code

The original English units of length were the mile, yard, foot and inch. The mile came to England from Ancient Rome, where it was defined as a thousand double steps of an armed Roman soldier

.

Old Russian system edit edit code

In Ancient Rus', the measure of length, weight, etc. was a person. This is indicated by the names of length measures: cubit (distance from the end of the extended middle finger of the hand or clenched fist to the elbow bend), span (distance between the extended thumb and index finger), fathom (distance from the end of the fingers of one hand to the end of the fingers of the other) and others [1].

In particular, the arshin was associated with the length of a human step. However, the need to unify measurement systems with the British one in connection with the development of international trade required the introduction of the so-called “state yardstick” during the time of Peter I. It was a measuring ruler with metal tips bearing the state mark. The official arshin was equal to 28 English inches and divided into 16 vershok. [2]
