To choose the right size TV for your home, which can have a diagonal of from 15 to 60 inches and larger, need to know the dimensions of the room in which the TV will be installed and arrangement of furniture in the room. In addition, immediately think of is the TV hanging on the wall, or stand on the stand.
If you know the future location of the TV in the room, you can calculate the diagonal of its screen based on the distance of the TV from where you watch it. TV diagonal should be chosen based on personal perception of the television image, but if you find this difficult, use the simple advice: the distance from the screen to the eyes should be equal to 5 diagonals of the screen. In other words, if the distance from the sofa to the wall where you will hang the TV is 4 feet, the optimal screen size for your situation will 81cm or 32 inches.
Also, you can use the rough table below to select the size of the TV (see illustration):
How to choose a TV. The type of screen. Traditionally, the size of the screen diagonal measured in inches and is, for example, so: 32”. It is easy to convert to centimeters: 1 inch = 2.54 cm to ensure that the viewing was comfortable, the screen size of the TV must match the size of the room in which you plan to put it.
How to choose a TV. Buying a TV is a serious matter, and approach to the selection of an indispensable element of modern life it is necessary responsibly. When choosing TV, it is first necessary to determine the diagonal size of the screen based on room dimensions, distance for comfortable viewing and Your own wishes. The fact is that if the TV is small, You will be hard to distinguish fine details, and if too big - the screen will be visible at certain points which do not improve the image.
Advice 2: How to determine the diagonal size of the TV
The definition of the diagonal of the TV may be needed for many reasons. For example, you need to calculate the optimal distance from TV to sofa or chair. Or do you need exact numbers for other purposes. Well, if the technical documentation for your consumer electronics is stored in one place, and you'll find the technical passport of your TV. But if I had the right documents were not available, would have to measure the diagonal of your own.
TVs generally come in rectangular shape. So, you need to calculate the diagonal of a rectangle using the settings of your TV screen. Diagonal in any polyhedron represents any segment that connects two vertices that are not adjacent.
In order to accurately determine the diagonal of your TV, measure its side. Remember that the screen starts not from the edge. On the edge of the screen, a part of the body, the size of which should be measured on the inner side. You need a diagonal that is screen and not the whole panel of the TV. That is the visible part.
Then remember the Pythagorean theorem and using this theorem calculate the desired diagonal. The formula of the Pythagorean theorem is the following: d = √(a2 + b2). d in this formula is the diagonal, a and b are the sides of the rectangle. Substitute the dimensions of the sides of the TV and get the diagonal size.
The disadvantage of this measurement is the diagonal of a TV is to measure the length of the sides, with a millimeter precision, you hardly will succeed. To do this with a ruler is difficult. Take some thread or string, stretch it along one of the sides of the TV, and then measure with a ruler. Do the same with the second side. Such a measurement method will be a little more accurate.
But if you decided to use a rope or thread, you can try to measure the diagonal without using the Pythagorean theorem. To do this, tighten the thread ends between nonadjacent vertices of a TV screen, and then measure the resulting length with a ruler.
To navigate the international dimensions, translate the results obtained into inches. 1 inch is equal to 2.4 cm, So you get the size of the diagonal of your TV set according to international standards.
There is another option that will probably be the easiest. Type in any search engine the model of your TV and find all the necessary technical characteristics.
Advice 3: How to calculate the diagonal of the TV
Wanting to buy a new TV, many are faced with the problem of choice. Even 20-30 years ago on the shelves of appliance stores stood 2-3 models of TV sets. Currently there are dozens of brands, hundreds of models, which differ by the set of functions, a reception mode, size, and price. However, for many the decisive factor is the choice of the diagonal of the TV.
Screen size (diagonal size) and the dimensions of the TV are calculated based on the size of the premises, where there will be vehicles to be purchased, the distance from the viewer to the screen and its purpose.
The parameters of the diagonal expressed in inches ("), and usually indicates 2 digits – diagonal visible area of the image and the full size of the CRT or liquid crystal matrix. Some companies go to the tricks and point not visible, but full size, so when buying you should check both indicators.
All televisions usually belong to several groups. Most often it is 14", 20", 21", 25", 32" and 36" screens. Along with the growth of the diagonal increase and the size of the TV. So if you are planning to buy a flat screen TV from 25", then immediately calculate and place under the TV, even LCD TV has a depth of 60 cm To the same? safety standards between the housing and the wall or walls of the niche should be a gap to prevent overheating of equipment.
According to the same safety standards, but for health, you need to calculate diagonal size and at the recommended distance from the viewer's eye to the screen. If this is the standard TV 4:3 format, the distance should be not less than 3, but better 5 the diagonals of TV.
Think what place will be organized by watching TV, where there will be a TV, measure the distance and divide it by 5. The resulting figure will be the maximum diagonal of the TV. For example, a chair on which to sit a spectator, separated from television cabinets to 3 meters, it turns out that the optimal diagonal will be 60 cm or 24 inches.
Divide the distance in 3 is only in the case if you aim to purchase LCD TV with a scan of at least 100 Hz and 4:3 format. Such TVs at a relatively close distance a flickering screen which is the main negative factor affecting health, almost imperceptibly.
Radiation at such distances is not harmful, it can pose a hazard only in the immediate vicinity of the screen at a distance of a few centimeters. For LCD TV format 16:9 recommended distance is at least 2.5 diagonal screen.
Advice 4: What is the optimal size of the rooms in the house
During the Soviet era, when private ownership of land did not exist, area, layout, size and number of storeys of private houses was strictly regulated. In most localities two-storey houses it was impossible to build at all. Currently, the area of the house which you can build, is limited essentially only by the size of your site and its floors – the rules of land use and development, but the house, at least 3 floors can be built on any plot intended for housing.
When in 90-ies of the last century in Russia saw the ownership of land was abolished and planning constraints in the construction of residential houses, many owners who constructed a new individual house, built entire castles. These homes with awkward floor plan, according to the projects created by the inexperienced in the construction of individual architects, very quickly disappointed their owners. The rooms were too large, and their number exceeds the needs of one family.
The result was that these houses were not used completely, in a huge ugly room, no one lived, but had a lot of money, time and effort spend on maintaining them in a habitable form. And with the growth of tariffs for housing these huge houses just ruined their owners, many of whom tried to sell them as quickly as possible. Today, those who are going to build a new house, try not to repeat such mistakes and design it to fit the real needs of his family.
The optimal size of the premises in an individual residential house
Of course, the main room in any residential building will be the living room, the room where family members and guests, sometimes it is expedient to combine with the dining room. Very convenient if adjacent areas will be for the living room kitchen and spacious veranda with a beautiful view or just around a lot of greenery. The most rational option when living and communicating, but it should not leave the doors of bedrooms. Optimal area living-dining area is calculated by the number of family members residing in the house. For a family of 4-5 people is enough living room size 18-20 sqm for 6-7 people – 22-24 sq m, even with the occasional guests.
The number of beds also depends on how many people will live in the house constantly, each of them must be separate sleeping room, not counting the couples. For accommodation you can provide one, maximum two additional bedrooms. Minimum bedroom size per person - 1,5x2,5 m, such a bedroom can make a guest. Bedroom for residing in the house of a man should hold a wardrobe for linen and clothes, or there should be built-in niche for such purposes anywhere in the room. So for master bedroom size 2.1 x 2.5 m or 2,8x2,5 m would be optimal.
As for the kitchen, if the living area is from 16 to 50 sq. m, it will be a size 6-8 sq m, if covered area is more, increase the size of the kitchen to 10-14 sq. m.
