Why the diagonal is not enough
Screens are advertised by their diagonal, and a diagonal does not determine width until you also know the shape. The same 16-inch measurement produces a screen 2.6 inches wider at 32:9 than at 4:3. If you are measuring a space, the width is the number that matters.
| Aspect ratio | Width | Height | Screen area |
|---|---|---|---|
| 16:9 — the standard for televisions and most monitors | 13.9 in / 35.4 cm | 7.8 in / 19.9 cm | 109 in² |
| 16:10 — taller than widescreen, common on laptops and design monitors | 13.6 in / 34.5 cm | 8.5 in / 21.5 cm | 115 in² |
| 21:9 — the 34-inch class ultrawide, actually 43:18 | 14.8 in / 37.5 cm | 6.2 in / 15.7 cm | 91 in² |
| 4:3 — the pre-widescreen shape, still used by projectors and older panels | 12.8 in / 32.5 cm | 9.6 in / 24.4 cm | 123 in² |
| 32:9 — two 16:9 panels side by side in one screen | 15.4 in / 39.1 cm | 4.3 in / 11.0 cm | 67 in² |
How it compares by area
A diagonal is a length, so a step up sounds smaller than it is: moving from 15.6 inches to 16 adds 0.4 inches of diagonal and 5% more picture, and the next size up, 17 inches, is another 13% again.
| Size | Width | Screen area | vs 16-inch |
|---|---|---|---|
| 13.3 in | 11.6 in | 76 in² | -31% |
| 14 in | 12.2 in | 84 in² | -23% |
| 15.6 in | 13.6 in | 104 in² | -5% |
| 17 in | 14.8 in | 123 in² | +13% |
| 19 in | 16.6 in | 154 in² | +41% |
| 21.5 in | 18.7 in | 198 in² | +81% |
| 22 in | 19.2 in | 207 in² | +89% |
| 24 in | 20.9 in | 246 in² | +125% |
Pixel density at 16-inch
The same resolution is sharp on a small screen and coarse on a large one, because sharpness is pixels per inch and the inches are not in the resolution.
| Resolution | Density at 16-inch | |
|---|---|---|
| Full HD (1920×1080) | 138 PPI | Sharp at desk distance |
| QHD (2560×1440) | 184 PPI | Sharp at desk distance |
| 4K UHD (3840×2160) | 275 PPI | Very high — the interface will be scaled |
| 8K UHD (7680×4320) | 551 PPI | Very high — the interface will be scaled |
Frequently asked questions
How wide is a 16-inch screen?
A 16-inch 16:9 screen is 13.9 inches (35.4 cm) wide and 7.8 inches (19.9 cm) tall. The diagonal alone does not fix the width — a 16-inch 4:3 screen is 12.8 inches wide instead.
What are the dimensions of a 16-inch TV in cm?
35.4 × 19.9 cm for the screen itself at 16:9. The cabinet is larger — usually 1 to 3 cm on each side for a modern set, more if it has a bezel — so measure the product rather than the panel when checking whether it fits a space.
Is a 16-inch screen much bigger than a 15.6-inch one?
By area, 5% bigger. Screens are sold by diagonal, which understates every step: going up 0.4 inches of diagonal here adds 5% of picture.
What resolution should a 16-inch screen be?
Pixel density decides that: Full HD gives 138 PPI, QHD gives 184 PPI, 4K UHD gives 275 PPI, 8K UHD gives 551 PPI. Below about 80 PPI a screen looks coarse at desk distance but is fine across a room, which is why televisions and monitors of the same size are sold at different resolutions.
