How Big Is a 25 Inch Monitor?
A 25-inch 16:9 monitor measures about 21.8 inches wide and 12.3 inches tall. It's only one inch larger diagonally than a 24-inch, but that translates to about 8% more screen area — enough that some people notice the difference and some don't. This size has become popular at 1440p, where the slightly larger panel makes the higher resolution more visually impactful than on a 24-inch screen.

Resolution and Pixel Density at 25 Inches
| Resolution | Pixel Density |
|---|---|
| 1080p (Full HD) | 88.1 PPI |
| 1440p (QHD) | 117.5 PPI |

Ideal resolution: 1440p (QHD)
At 25 inches, 1440p gives you 117 PPI — noticeably sharper than 1080p (88 PPI) without needing any Windows scaling. Text is crisp, UI elements are well-proportioned, and you get meaningfully more workspace than at 1080p. This is the smallest size where 1440p starts to really shine.
Who Should Buy a 25-Inch Monitor?
Gamers who want sharp visuals: Combines the compact, easy-to-scan size that competitive gamers prefer with 1440p sharpness. A growing number of esports-adjacent players are moving to 25-inch 1440p 240Hz monitors as a best-of-both-worlds option.
Developers: At 1440p without scaling, you can fit more code on screen than at 1080p — about 30% more lines vertically. The 25-inch size keeps everything readable without making you lean in.
General productivity: A subtle but meaningful upgrade from 24 inches if you're buying new. The extra inch and higher resolution make everyday tasks slightly more comfortable.
Viewing Distance
Recommended: 22-30 inches (55-75 cm)
Very similar to 24-inch recommendations. At arm's length, the screen fills your field of view just enough for immersion without overwhelming your peripheral vision.
Desk Space Requirements
Nearly identical footprint to a 24-inch monitor. You won't need to rearrange your desk — the difference is about half an inch on each side.
How 25 Inches Compares to Other Sizes
vs. smaller monitors: The jump from 24 to 25 inches is subtle — about 8% more area. The bigger upgrade is usually resolution (1080p to 1440p) rather than the physical size increase.
vs. larger monitors: A 27-inch monitor is 17% larger and gives you a more noticeably immersive experience. If you're already moving to 1440p, 27 inches is the more popular choice. But 25 inches is better if you prefer the tighter field of view for competitive gaming.
Buying Advice
The 25-inch market is dominated by 1440p high-refresh-rate gaming monitors. If you're buying this size, you're likely choosing it specifically for the 1440p + compact size combination. Make sure you have a GPU that can drive 1440p at your target frame rate — at least an RTX 4060 or RX 7600 class card for 60fps, more for high refresh rate gaming.
