The 25 inch exists mostly for one buyer: someone who plays fast games and wants every frame. It is a size defined by a panel and not by a desk, and that panel is a 24.5 inch one.
Which size do you mean?
- 55.3 cm by 31.1 cm is the screen of a true 25 inch 16:9 panel, worked out from the 63.5 cm diagonal.
- 54.2 by 30.5 cm is the screen of a 24.5 inch panel, the one inside most monitors sold as 25 inch. It is about a centimetre narrower.
- About 56.9 cm by 33.7 cm is the monitor with its bezels, and about 42.7 cm tall on its stand. This is the width a desk has to hold.

24.5 inch or 25 inch
Most 25 inch monitors carry a 24.5 inch panel, 54.2 cm wide, with 1,920 by 1,080 pixels, which works out to about 90 pixels per inch. That is slightly coarser than a 24 inch at 1080p, and the trade is deliberate: fewer pixels means a graphics card can feed the panel at the frame rates it is built for. A handful of true 25 inch models run at 2,560 by 1,440 and about 117 pixels per inch. Those are aimed at office work, and are the better choice if you read more than you play.
A centimetre of difference between the name and the panel never shows on a desk. It matters for a gap measured closely and for a matched pair.
Drawn to scale
At 56.9 cm of body the monitor uses 41% of a 140 cm desk and under half of a 120 cm one, which leaves space for a wide mouse mat, the reason many players pick it over a 27 inch in the first place. Check the stand’s 18 cm of depth as well as the width, because on a small desk it is the figure that decides.
Next to the sizes either side
Against the 25, the 24 inch is 4% narrower with 8% less screen, and the 27 inch is 8% wider with 17% more.
| Size | Active width | Width | Screen area |
|---|---|---|---|
| 24" | 53.1 cm | −4% | −8% |
| 27" | 59.8 cm | +8% | +17% |
The 24 inch page has the same tables for the size below.
25 inch against 27 inch
Measured against the 25, a 27 inch is 4.4 cm wider across and 2.5 cm taller top to bottom. It has 8% more diagonal and 16.6% more screen, a bigger step than two inches sounds. How far to sit from a 27 inch monitor shows the extra distance the larger size asks for.
How much desk does it need?
| Space | Size | Fits? | Detail |
|---|---|---|---|
| Compact desk | 100 cm × 50 cm | Fits | 57% of the width, 43.1 cm spare in all |
| Standard desk | 120 cm × 60 cm | Fits | 47% of the width, 63.1 cm spare in all |
| Large desk | 140 cm × 70 cm | Fits | 41% of the width, 83.1 cm spare in all |
| Deep desk | 160 cm × 80 cm | Fits | 36% of the width, 103.1 cm spare in all |
Width is rarely the problem. A single 25 inch monitor uses 57% of a 100 cm desk and 47% of a 120 cm one. Two side by side need about 115.9 cm, counting a 2 cm gap, which does not fit a 100 cm desk and only just fits a 120 cm one.
The whole picture in your view
| Used for | Sit | In feet | Field of view |
|---|---|---|---|
| Work / productivity | 0.5 m – 0.7 m | 1 ft 8 in – 2 ft 4 in | 42–56° |
| Coding | 0.5 m – 0.7 m | 1 ft 9 in – 2 ft 4 in | 42–54° |
| Design | 0.5 m – 0.7 m | 1 ft 8 in – 2 ft 3 in | 44–58° |
| Gaming | 0.4 m – 0.6 m | 1 ft 5 in – 2 ft 0 in | 48–64° |
| Movies | 0.4 m – 0.6 m | 1 ft 5 in – 1 ft 11 in | 50–66° |
| Mixed | 0.5 m – 0.7 m | 1 ft 6 in – 2 ft 2 in | 45–61° |
Sit 0.5 m to 0.7 m away for desk work and 0.4 m to 0.6 m for games, and a 25 inch monitor fills 42° to 56° and 48° to 64° of your view. From the middle of the work range, about 60 cm, it spans close to 50°, which is the point of the size for competitive play: the corners of the screen, where the map and the timers are, stay within an easy glance. A 27 inch at the same distance spans about 53°, and a 32 inch about 61°.
Full HD or 1440p at 25 inches
| Resolution | Pixels | Pixels per inch | Sharp from | Pixels invisible from |
|---|---|---|---|---|
| 1080p | 1920 × 1080 | 88 | 0.7 m | 1 m |
| 1440p | 2560 × 1440 | 117 | 0.6 m | 0.7 m |
| 4K | 3840 × 2160 | 176 | 0.4 m | 0.5 m |
At 88 pixels per inch, single pixels stop showing from about 1 m at 1080p, and from 0.7 m at 1440p, where the density is 117. A game seat of 0.4 m to 0.6 m is inside both distances, so a 1080p picture shows a little grain and 1440p shows less.
The 60 pixels per degree behind those distances is a convention. A 2025 paper in Nature Communications reported a mean of about 94 pixels per degree for fine detail, so a careful reader of small text will want 1440p.
Stands, arms and mounting
The VESA pattern, where a monitor has one, is listed in millimetres on the spec sheet. An arm that clamps to the back edge gives back the stand’s depth, and its weight rating should be checked against the monitor’s as well as the pattern.
Who a 25 inch suits
A 25 inch suits a player or a second screen on a desk of 100 cm or more, and a seat about 60 cm from the screen. It is a competitive size, built so the whole picture sits in view.
If the work is mostly reading, a 27 inch at 1440p is the more common choice, and what size monitor do I need works from the desk and the task.
Common questions
- Why are 25 inch monitors 24.5 inches?
- Because the size is built around one kind of panel: 24.5 inches, 1,920 by 1,080, made for high refresh rates. The name rounds it up to 25. That panel is 54.2 cm wide and 30.5 cm tall, with about 90 pixels per inch. A small number of true 25 inch models exist at 2,560 by 1,440, and those are a different screen, at about 117 pixels per inch.
- How big is a 25 inch monitor compared with a 24 inch?
- Very slightly bigger: 55.3 cm of screen against 53.1 cm, which is 4% more width and 8% more area. Most 25 inch models are 24.5 inch panels, 54.2 cm wide, so the practical difference from a 24 inch is about a centimetre.
- Is a 25 inch monitor good for gaming?
- It is what the size is mostly made for. At 60 cm the screen spans close to 50° of your view, inside the 48° to 64° the calculator uses for gaming, so the corners, where the map and timers sit, stay within an easy glance. A 27 inch at the same distance spans about 53°, and a 32 inch about 61°.
- Can two 25 inch monitors fit on a 120 cm desk?
- Just. Two side by side need about 115.9 cm, counting a 2 cm gap, which leaves about 4.1 cm on a 120 cm desk and does not fit a 100 cm one. For a dual setup on a standard desk, the 24 inch has a little more room to spare.
- What resolution is a 25 inch monitor?
- Usually 1,920 by 1,080 at a high refresh rate. At 1080p the density is about 88 pixels per inch on a true 25 inch and about 90 on the 24.5 inch panel. At 2,560 by 1,440 it is about 117, which is the better choice if you read more than you play.
How we worked this out
Everything marked approx. assumes a bezel of 0.8 cm at each side, 0.8 cm at the top and 1.8 cm at the bottom, 9 cm of stand height and 18 cm of stand depth. Real sets vary by a centimetre or two, so the spec sheet of the model you are buying has the last word.
