Width, height, diagonal, and viewing distance for every standard TV size — 32 to 98 inches.
Last updated: April 2026
All dimensions are for the screen only (16:9 aspect ratio). Add 2–4 cm per side for the physical unit including the bezel. Viewing distance is the recommended range: multiply the diagonal in cm by 1.5 (minimum) and 2.5 (maximum).
| Size | Diagonal | Width | Height | Width (in) | Height (in) | Viewing distance |
|---|---|---|---|---|---|---|
| 32″ | 81.3 cm | 70.7 cm | 39.8 cm | 27.8″ | 15.7″ | 1.2 – 2.0 m |
| 40″ | 101.6 cm | 88.5 cm | 49.8 cm | 34.8″ | 19.6″ | 1.5 – 2.5 m |
| 43″ | 109.2 cm | 95.1 cm | 53.5 cm | 37.5″ | 21.1″ | 1.6 – 2.7 m |
| 50″ | 127.0 cm | 110.7 cm | 62.3 cm | 43.6″ | 24.5″ | 1.9 – 3.2 m |
| 55″ | 139.7 cm | 121.7 cm | 68.5 cm | 47.9″ | 27.0″ | 2.1 – 3.5 m |
| 65″ | 165.1 cm | 143.8 cm | 80.9 cm | 56.6″ | 31.8″ | 2.5 – 4.1 m |
| 75″ | 190.5 cm | 166.1 cm | 93.4 cm | 65.4″ | 36.8″ | 2.9 – 4.8 m |
| 85″ | 215.9 cm | 188.0 cm | 105.8 cm | 74.0″ | 41.7″ | 3.2 – 5.4 m |
| 98″ | 248.9 cm | 216.8 cm | 122.0 cm | 85.4″ | 48.0″ | 3.7 – 6.2 m |
The diagonal is the marketed size (e.g. "55 inch TV"). Width and height are the actual screen dimensions in centimetres and inches. Use the width to check whether the TV fits your wall, shelf, or TV unit. Use the height to calculate the mounting position.
Viewing distance is based on a standard formula: minimum = diagonal × 1.5, maximum = diagonal × 2.5 (in centimetres, then divided by 100 to give metres). The closer end suits 4K Ultra HD content; the farther end suits 1080p HD content and larger rooms.
Going from 55 to 65 inches adds 22 cm to the width and 12 cm to the height — a meaningful increase, but the jump from 65 to 75 inches is similar (22 cm wider). From 75 to 85 inches adds another 22 cm of width. Each size step up in this range is roughly the same physical jump.
The most popular sizes globally are 55 and 65 inches — both fit standard living rooms, and the price gap has narrowed significantly in recent years.
A 55 inch TV has a screen diagonal of 139.7 cm (55 inches), a width of 121.7 cm (47.9 inches), and a height of 68.5 cm (27.0 inches). These are screen-only dimensions for a 16:9 aspect ratio. The physical unit including the frame is typically 2–4 cm wider and taller. The recommended viewing distance is 2.1–3.5 metres.
TV sizes are always measured diagonally — from the bottom-left corner of the screen to the top-right corner — in inches. This is the screen-only measurement and does not include the bezel or stand. A "55 inch TV" has a screen diagonal of exactly 55 inches (139.7 cm). The actual width and height of the unit will always be larger than this diagonal figure.
The largest standard consumer TV size is 98 inches — 216.8 cm wide and 122.0 cm tall. This requires a very large room and a minimum viewing distance of about 3.7 metres. Some manufacturers produce 110 inch and larger screens, but these are typically commercial or custom units. For home cinema use, 85–98 inches is the practical upper limit for most rooms.
The key number is your viewing distance — measured from the sofa to the TV wall. Divide that distance in centimetres by 2.5 to get the maximum comfortable screen diagonal in cm, then divide by 2.54 to convert to inches. For example: a 3 metre (300 cm) viewing distance works best with a screen up to 120 cm diagonal ÷ 2.54 = 47 inches. The closest standard size is 50 inches. Use the chart above to check that the width also fits your wall or unit.
