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 43-inch measurement produces a screen 7.0 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 | 37.5 in / 95.2 cm | 21.1 in / 53.5 cm | 790 in² |
| 16:10 — taller than widescreen, common on laptops and design monitors | 36.5 in / 92.6 cm | 22.8 in / 57.9 cm | 831 in² |
| 21:9 — the 34-inch class ultrawide, actually 43:18 | 39.7 in / 100.7 cm | 16.6 in / 42.2 cm | 659 in² |
| 4:3 — the pre-widescreen shape, still used by projectors and older panels | 34.4 in / 87.4 cm | 25.8 in / 65.5 cm | 888 in² |
| 32:9 — two 16:9 panels side by side in one screen | 41.4 in / 105.1 cm | 11.6 in / 29.6 cm | 482 in² |
How it compares by area
A diagonal is a length, so a step up sounds smaller than it is: moving from 40 inches to 43 adds 3.0 inches of diagonal and 16% more picture, and the next size up, 49 inches, is another 30% again.
| Size | Width | Screen area | vs 43-inch |
|---|---|---|---|
| 29 in | 25.3 in | 359 in² | -55% |
| 32 in | 27.9 in | 438 in² | -45% |
| 34 in | 29.6 in | 494 in² | -37% |
| 38 in | 33.1 in | 617 in² | -22% |
| 40 in | 34.9 in | 684 in² | -13% |
| 49 in | 42.7 in | 1026 in² | +30% |
| 50 in | 43.6 in | 1068 in² | +35% |
| 55 in | 47.9 in | 1293 in² | +64% |
Pixel density at 43-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 43-inch | |
|---|---|---|
| Full HD (1920×1080) | 51 PPI | Television distance only |
| QHD (2560×1440) | 68 PPI | Fine across a room, coarse up close |
| 4K UHD (3840×2160) | 102 PPI | Comfortable at desk distance |
| 8K UHD (7680×4320) | 205 PPI | Very high — the interface will be scaled |
Frequently asked questions
How wide is a 43-inch screen?
A 43-inch 16:9 screen is 37.5 inches (95.2 cm) wide and 21.1 inches (53.5 cm) tall. The diagonal alone does not fix the width — a 43-inch 4:3 screen is 34.4 inches wide instead.
What are the dimensions of a 43-inch TV in cm?
95.2 × 53.5 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 43-inch screen much bigger than a 40-inch one?
By area, 16% bigger. Screens are sold by diagonal, which understates every step: going up 3.0 inches of diagonal here adds 16% of picture.
What resolution should a 43-inch screen be?
Pixel density decides that: Full HD gives 51 PPI, QHD gives 68 PPI, 4K UHD gives 102 PPI, 8K UHD gives 205 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.
