How large is a TV in inches and how many centimetres is that?
A 55-, 65- or 75-inch television: how large is it really? The screen size indicates the diagonal of the screen, not the width. One inch is exactly 2.54 centimetres. Use the conversion table below to compare screen sizes and determine how much space you need on the wall, in your media wall or on a TV stand.
You will also learn how to determine the viewing distance, which viewing height is comfortable and how to choose a suitable TV mount. This page is about screen size and viewing distance. For measuring the mounting holes, we have a separate comprehensive VESA guide.

How do you measure the screen size of your television?
Measure the diagonal of the visible screen: from one screen corner diagonally to the opposite screen corner. Do not include the edge of the casing in the measurement. Divide the number of centimetres by 2.54 to calculate the screen size in inches. For example, if you measure approximately 139.7 cm diagonally, the screen is 55 inches.
Do you mainly want to know whether your television fits a mount? In addition to the screen size, you need the VESA size and the weight without the stand. The same screen size can have a different VESA pattern depending on the manufacturer.
What is a comfortable viewing distance for 55, 65, 75, 85 or 98 inches?
The ideal viewing distance is not a fixed number. It depends on the image resolution, your preference, the type of content and how large you want the image to appear in your field of vision. For a modern 4K TV, the distance below is a practical starting point for an immersive viewing experience, not a mandatory distance.
| Size | Starting point for viewing distance |
|---|---|
| 43 inches | approx. 1.3–1.8 m |
| 55 inches | approx. 1.7–2.3 m |
| 65 inches | approx. 2.0–2.7 m |
| 75 inches | approx. 2.3–3.1 m |
| 85 inches | approx. 2.6–3.5 m |
| 98 inches | approx. 3.0–4.1 m |
For sports and films, sitting closer can be enjoyable; for news or prolonged viewing, some people prefer a little more distance. Try out the viewing distance beforehand using painter's tape on the wall.
4K, 8K, and viewing angle: why the distance varies
The closer you sit to a large screen, the larger the image appears in your field of vision. This can make films and games more immersive, but you must also be able to view the entire screen comfortably. With lower image resolution or heavily compressed broadcasts, image flaws are more noticeable from close up. With good 4K content, you can generally sit closer without distinguishing individual pixels. 8K is not automatically a visible advantage: screen size, distance, and available source material all play a role.
Also consider reflections from windows and lighting, as well as the position of the sofa. A good position in the room often has more influence on viewing comfort than a difference of a few centimeters in viewing distance.
How high should you mount a large TV?
In a living room, it is usually comfortable to look straight ahead without having to tilt your neck upward for long periods. With large screens, the bottom edge may end up lower than you initially expect. Therefore, first determine your normal sitting position, the distance from the TV, and the position of the center of the screen. Then mark the screen width and height on the wall.
In the bedroom, you often watch from a lying position, so a different height or a tilting mount may be more logical. In a meeting room, shop window, or hospitality venue, sightlines and walking routes are important. Read our separate guide: how high should I mount my TV?
Which TV mount is suitable for your screen size?
You should never choose a TV mount solely based on inches. Check three things: the supported screen diagonal, the weight without the stand, and the exact VESA size. The wall construction, distance from the wall, and desired swivel or tilt angle are also decisive.
With larger televisions, the forces on the wall are greater, especially when you extend a swivel mount far out. For large screens, you can view our range of sturdy TV mounts for large televisions. Looking for a general solution? View all TV wall mounts or ceiling mounts up to 75 inches.
Before ordering, read our explanation of VESA sizes, so you know which mounting points your television has.
Frequently asked questions about inch sizes and TV dimensions
How many centimeters is 1 inch?
Exactly 2.54 centimeters. Multiply the number of inches by 2.54 to calculate the screen diagonal in centimeters.
How wide is a 55-inch TV?
For a 16:9 screen, the visible image is approximately 121.8 cm wide. The housing may be slightly wider.
How wide is a 65-inch TV?
At 16:9, the visible screen is approximately 143.9 cm wide. Measure the actual outer dimensions if you have a niche or media wall.
How wide is a 75-inch TV?
The visible 16:9 screen is approximately 166.0 cm wide. The total TV may be wider.
Is 65 inches the width or the diagonal?
The diagonal. The width is approximately 143.9 cm for a 16:9 screen.
Which inch size is suitable for a three-meter viewing distance?
That depends on your preference and the material. A 75 to 98-inch screen could be a good candidate at that distance, but try out the size beforehand.
Does a larger TV automatically have a different VESA size?
No. The mounting holes differ by brand and model. Measure the holes or consult the VESA guide.
Is a larger TV always better?
Not necessarily. Viewing comfort, available wall width, reflections, viewing distance, and the quality of the source material are at least as important.
