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 14-inch measurement produces a screen 2.3 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 | 12.2 in / 31.0 cm | 6.9 in / 17.4 cm | 84 in² |
| 16:10 — taller than widescreen, common on laptops and design monitors | 11.9 in / 30.2 cm | 7.4 in / 18.8 cm | 88 in² |
| 21:9 — the 34-inch class ultrawide, actually 43:18 | 12.9 in / 32.8 cm | 5.4 in / 13.7 cm | 70 in² |
| 4:3 — the pre-widescreen shape, still used by projectors and older panels | 11.2 in / 28.4 cm | 8.4 in / 21.3 cm | 94 in² |
| 32:9 — two 16:9 panels side by side in one screen | 13.5 in / 34.2 cm | 3.8 in / 9.6 cm | 51 in² |
How it compares by area
A diagonal is a length, so a step up sounds smaller than it is: moving from 13.3 inches to 14 adds 0.7 inches of diagonal and 11% more picture, and the next size up, 15.6 inches, is another 24% again.
| Size | Width | Screen area | vs 14-inch |
|---|---|---|---|
| 13.3 in | 11.6 in | 76 in² | -10% |
| 15.6 in | 13.6 in | 104 in² | +24% |
| 16 in | 13.9 in | 109 in² | +31% |
| 17 in | 14.8 in | 123 in² | +47% |
| 19 in | 16.6 in | 154 in² | +84% |
| 21.5 in | 18.7 in | 198 in² | +136% |
| 22 in | 19.2 in | 207 in² | +147% |
| 24 in | 20.9 in | 246 in² | +194% |
Pixel density at 14-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 14-inch | |
|---|---|---|
| Full HD (1920×1080) | 157 PPI | Sharp at desk distance |
| QHD (2560×1440) | 210 PPI | Very high — the interface will be scaled |
| 4K UHD (3840×2160) | 315 PPI | Very high — the interface will be scaled |
| 8K UHD (7680×4320) | 629 PPI | Very high — the interface will be scaled |
Frequently asked questions
How wide is a 14-inch screen?
A 14-inch 16:9 screen is 12.2 inches (31.0 cm) wide and 6.9 inches (17.4 cm) tall. The diagonal alone does not fix the width — a 14-inch 4:3 screen is 11.2 inches wide instead.
What are the dimensions of a 14-inch TV in cm?
31.0 × 17.4 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 14-inch screen much bigger than a 13.3-inch one?
By area, 11% bigger. Screens are sold by diagonal, which understates every step: going up 0.7 inches of diagonal here adds 11% of picture.
What resolution should a 14-inch screen be?
Pixel density decides that: Full HD gives 157 PPI, QHD gives 210 PPI, 4K UHD gives 315 PPI, 8K UHD gives 629 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.
