How much bigger is a 28 inch monitor than a 27 inch?

Barely: 62 cm of screen against 59.8 cm, which is 4% more width and 7% more area. Side by side you would struggle to tell them apart. The difference between them is almost always the resolution and not the size.

What resolution is a 28 inch monitor?

Most are 4K, 3,840 by 2,160, which gives about 157 pixels per inch. That is sharp enough that you will run it at 150% scaling, which leaves you the same working space as a 1440p screen, 2,560 by 1,440, with noticeably crisper text.

Is a 28 inch 4K monitor good for work?

Yes, if you want sharp text more than extra space. At 150% scaling it shows as much as a 27 inch 1440p monitor, with every letter drawn from more pixels. If you want more on screen instead, a 32 inch 4K at 125% gives an effective 3,072 by 1,728.

Can two 28 inch monitors fit on a 140 cm desk?

Yes, with about 10.8 cm to spare. Two side by side need about 129.2 cm, counting a 2 cm gap, which is more than a 120 cm desk offers. On a narrower desk, stacking one above the other takes only the width of one.

How far should I sit from a 28 inch monitor?

For desk work, between about 0.6 m and 0.8 m, which is the distance at which the screen fills 42° to 56° of your view. That is a little further back than for a 27 inch.

28 inch monitor dimensions

Published 4 September 2026. Updated 25 October 2026. By the DisplayScale team.

A 28 inch monitor is 62 cm wide and 34.9 cm tall (24.4 in by 13.7 in) as a picture, and about 63.6 cm wide as a whole set.

Picture width: 62 cm; 24.4 in
Picture height: 34.9 cm; 13.7 in
Diagonal: 71.1 cm; 28 in
Whole set width: ≈ 63.6 cm; ≈ 25 in

The picture is measured on the glass of a 16:9 panel; the whole-set width adds an estimated bezel.

Few people choose a 28 inch because 28 is the size they wanted. They choose it because it comes at 4K, and the size came with it. The numbers below are for the case where the pixels, and not the inches, are the point.

Which size do you mean?

62 cm by 34.9 cm is the screen of a 16:9 panel, worked out from the 71.1 cm diagonal. It is a 27 inch with a centimetre more on each side.
About 63.6 cm by 37.5 cm is the monitor with its bezels. This is the width a desk has to hold, and anywhere a 27 inch fits this fits.
About 47.5 cm tall with the stand, which adds about 10 cm. The stand is closer to 22 cm deep than the 18 cm of a 24 or 27 inch stand.

Drawn to scale

A 28 inch monitor on a 140 cm desk, with a keyboard in front of it. One centimetre in the drawing is one centimetre on the desk.

On a 140 cm desk the monitor takes 45% of the width and leaves 76.4 cm for speakers or a second device. Side by side with a 27 inch the difference is hard to see, which is why the choice usually comes down to resolution.

Next to the sizes either side

The 28 inch solid, with the sizes either side dashed.

Against the 28, the 27 inch is 4% narrower with 7% less screen, and the 32 inch is 14% wider with 31% more.

The sizes either side, and how much bigger or smaller they are
Size	Active width	Width	Screen area
27"	59.8 cm	−4%	−7%
32"	70.8 cm	+14%	+31%

The 27 inch page has the same tables for the size below. The step up to a 32 is the one that changes the desk.

Compare any two screens

The step to a 32 inch adds 8.9 cm of width and 5 cm of height, with the diagonal 14.3% longer and 30.6% more screen, which is a larger leap than a 27 to a 28 and needs a deeper desk to sit back from.

How much desk does it need?

Whether this size fits each standard space, and by how much
Space	Size	Fits?	Detail
Compact desk	100 cm × 50 cm	Fits	64% of the width, 36.4 cm spare in all
Standard desk	120 cm × 60 cm	Fits	53% of the width, 56.4 cm spare in all
Large desk	140 cm × 70 cm	Fits	45% of the width, 76.4 cm spare in all
Deep desk	160 cm × 80 cm	Fits	40% of the width, 96.4 cm spare in all

At 63.6 cm of body a 28 inch uses 53% of a standard 120 cm desk and 64% of a compact 100 cm one, so it fits everywhere a 27 inch does. Two side by side need about 129.2 cm, counting a 2 cm gap, which fits a 140 cm desk and not a 120 cm one.

How far to sit

Comfortable viewing distance for a 28 inch monitor, by what it is used for
Used for	Sit	In feet	Field of view
Work / productivity	0.6 m – 0.8 m	1 ft 11 in – 2 ft 8 in	42–56°
Coding	0.6 m – 0.8 m	2 ft 0 in – 2 ft 8 in	42–54°
Design	0.6 m – 0.8 m	1 ft 10 in – 2 ft 6 in	44–58°
Gaming	0.5 m – 0.7 m	1 ft 8 in – 2 ft 3 in	48–64°
Movies	0.5 m – 0.7 m	1 ft 7 in – 2 ft 2 in	50–66°
Mixed	0.5 m – 0.7 m	1 ft 9 in – 2 ft 5 in	45–61°

Measured from your eyes to the face of the screen, for a 28 inch 16:9 monitor 62 cm wide. A wider target field of view means sitting closer, not further away.

Sit 0.6 m to 0.8 m away for ordinary work and 0.5 m to 0.7 m for games, and a 28 inch monitor fills 42° to 56° and 48° to 64° of your view. That is a little further back than for a 27 inch.

4K at 28 inches

Pixel density of a 28 inch monitor at each resolution, and how far back the pixels disappear
Resolution	Pixels	Pixels per inch	Sharp from	Pixels invisible from
1080p	1920 × 1080	79	0.8 m	1.1 m
1440p	2560 × 1440	105	0.6 m	0.8 m
4K	3840 × 2160	157	0.4 m	0.6 m

4K at this size is dense. Across 62 cm of screen, 3,840 pixels gives 157 pixels per inch, against 105 at 1440p and 79 at 1080p. By the 20/20 convention of 60 pixels per degree, single pixels stop showing from about 0.6 m at 4K, which is at the near end of the desk-work range above, so the pixel grid does not show from a normal seat.

At 100% scaling the text is too small for most eyes at desk distance, so the operating system suggests 150%. At 150% you work with an effective 2,560 by 1,440: the same room as a 27 inch at 1440p, drawn with more than twice the pixels. That is the reason to buy one. Text, photographs and fine lines in drawings look cleaner than at 1440p, and nothing gets bigger or smaller.

What it is not

A 28 inch at 4K is not more space than a 27 inch at 1440p. At 150% it shows exactly the same number of windows, only sharper. If more room is the goal, a 32 inch at 4K and 125% scaling gives an effective 3,072 by 1,728 and needs a desk that can put you about 0.7 m or more from the screen. The monitor scaling calculator shows the working space for any size at each setting.

A 2025 paper in Nature Communications reported a mean of about 94 pixels per degree for fine black and white detail, so even a 4K panel at 28 inches is near the point where the eye gains little from more pixels.

Stands, arms and mounting

Where a monitor has mounting holes they follow the VESA standard, listed in millimetres on the spec sheet. Look at the stand’s base as well as the pattern, and consider an arm if the desk is shallow, because it gives back the stand’s depth.

Who a 28 inch suits

A 28 inch suits someone who wants a 27 inch with a sharper picture, on a standard desk and a seat about 0.6 m to 0.8 m from the screen. It is the size for text and photographs more than for extra windows.

If the desk is shallow or the budget points at 1440p, a 27 inch is the simpler choice. What size monitor do I need works from the desk and the task.

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, 10 cm of stand height and 22 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.
