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 98-inch measurement produces a screen 15.9 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 | 85.4 in / 217.0 cm | 48.0 in / 122.0 cm | 4104 in² |
| 16:10 — taller than widescreen, common on laptops and design monitors | 83.1 in / 211.1 cm | 51.9 in / 131.9 cm | 4316 in² |
| 21:9 — the 34-inch class ultrawide, actually 43:18 | 90.4 in / 229.6 cm | 37.8 in / 96.1 cm | 3421 in² |
| 4:3 — the pre-widescreen shape, still used by projectors and older panels | 78.4 in / 199.1 cm | 58.8 in / 149.4 cm | 4610 in² |
| 32:9 — two 16:9 panels side by side in one screen | 94.3 in / 239.6 cm | 26.5 in / 67.4 cm | 2503 in² |
How it compares by area
A diagonal is a length, so a step up sounds smaller than it is: moving from 85 inches to 98 adds 13.0 inches of diagonal and 33% more picture.

Pixel density at 98-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 98-inch | |
|---|---|---|
| Full HD (1920×1080) | 22 PPI | Television distance only |
| QHD (2560×1440) | 30 PPI | Television distance only |
| 4K UHD (3840×2160) | 45 PPI | Television distance only |
| 8K UHD (7680×4320) | 90 PPI | Comfortable at desk distance |
Frequently asked questions
How wide is a 98-inch screen?
A 98-inch 16:9 screen is 85.4 inches (217.0 cm) wide and 48.0 inches (122.0 cm) tall. The diagonal alone does not fix the width — a 98-inch 4:3 screen is 78.4 inches wide instead.
What are the dimensions of a 98-inch TV in cm?
217.0 × 122.0 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 98-inch screen much bigger than a 85-inch one?
By area, 33% bigger. Screens are sold by diagonal, which understates every step: going up 13.0 inches of diagonal here adds 33% of picture.
What resolution should a 98-inch screen be?
Pixel density decides that: Full HD gives 22 PPI, QHD gives 30 PPI, 4K UHD gives 45 PPI, 8K UHD gives 90 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.
