How big is a 27 inch monitor with the stand?
Stands add height and depth, and frame widths vary. Here are the real measurements of popular 27 inch monitors from their makers' spec sheets.
Each model name links to its maker's spec sheet. Prices open on Amazon (affiliate links).
What did the real models show?
The table lists four 27 inch monitors, all from Dell. Their bodies are 24.0 in61.1 cm to 24.1 in61.2 cm wide, or 0.5 in1.3 cm to 0.6 in1.4 cm more than the screen itself. With under 1 in (2.5 cm) between them, the frame rarely decides whether one of these fits.
Without its stand, the Dell SE2726H is the thinnest at 1.9 in4.9 cm deep. At the other end, the Dell S2725QS is 2.4 in6.0 cm deep.
Weights run from 7.96 lb3.6 kg for the Dell SE2726H to 10.05 lb4.6 kg for the Dell S2725QS. A monitor arm rated for 11 lb5.0 kg or more covers the weight of every model here.
With their stands, the makers list heights of 15.1 in38.5 cm to 17.9 in45.4 cm, so measure under any shelf. On their stands, they take 7.6 in19.2 cm to 7.9 in20.0 cm of desk depth.
All four share one VESA pattern, 100 x 100 mm, so one arm pattern covers them all.
Will a 27 inch monitor fit on your desk?
Enter the space on your desk, under any shelf or cabinet. We check it against the screen, and the table above shows what each stand adds.
How much desk do two or three need?
Two 27 inch screens side by side need at least 47.1 in119.5 cm (119.5 cm47.1 in) of desk width for the screens alone. Three need 70.6 in179.3 cm (179.3 cm70.6 in). Add the frame widths from the table above.
Two side by side are about as wide as one 49 inch ultrawide, with a frame down the middle.
How far should you sit from a 27 inch monitor?
Desk screens are usually viewed from 20 to 30 in (50 to 75 cm). The table shows how much of your view a 27 inch screen fills at each distance. It feels very wide at 18 to 24 in46 to 61 cm and wide at 28 to 32 in71 to 81 cm.
Which resolution suits a 27 inch monitor?
Higher resolution looks sharper but makes text smaller, so you need display scaling. At 27 inches, 1920 × 1080 gives 82 PPI and 3840 × 2160 gives 163 PPI. The table shows the Windows scaling each needs.
At this size, 1920 × 1080 looks soft, 2560 × 1440 looks clear and 3840 × 2160 looks very sharp. 1920 × 1080 works at 100% scaling, while 2560 × 1440 needs 125% and 3840 × 2160 needs 175%.
Sit farther away than the last column and you will not see single pixels. See every resolution in the chart.
How does a 27 inch monitor compare with other sizes?
The next size up, the 28 inch monitor, has 8% more screen area. The next size down, the 25 inch monitor, has 14% less screen area. Area grows with the square of the diagonal, so a few inches feel bigger than they sound.
That makes the size up a small step, and the size down a clear step.

How we measure
Screen width = diagonal x a / sqrt(a^2 + b^2) and height = diagonal x b / sqrt(a^2 + b^2) for an a:b screen. Viewing angle = 2 x arctan(half the screen width / distance). Pixel visibility uses 1 arcminute, the limit of 20/20 vision.
