How big is a 24 inch monitor with the stand?
Stands add height and depth, and frame widths vary. Here are the real measurements of popular 24 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 eight 24 inch monitors from Dell, AOC and ViewSonic. Their bodies are 21.2 in53.8 cm to 21.4 in54.4 cm wide, or 0.3 in0.7 cm to 0.5 in1.3 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 AOC 24G50F and AOC 24G51F are the thinnest at 1.4 in3.6 cm deep. At the other end, the Dell P2426H is 2.0 in5.0 cm deep.
Weights run from 4.96 lb2.2 kg for the AOC 24G50F and AOC 24G51F to 7.76 lb3.5 kg for the Dell U2424H. A monitor arm rated for 8 lb3.6 kg or more covers the weight of every model here.
With their stands, the makers list heights of 14.3 in36.4 cm to 16.9 in43.1 cm, so measure under any shelf. On their stands, they take 6.7 in17.1 cm to 7.6 in19.3 cm of desk depth.
All eight share one VESA pattern, 100 x 100 mm, so one arm pattern covers them all.
Will a 24 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 24 inch screens side by side need at least 41.8 in106.3 cm (106.3 cm41.8 in) of desk width for the screens alone. Three need 62.8 in159.4 cm (159.4 cm62.8 in). Add the frame widths from the table above.
Two side by side are about as wide as one 45 inch ultrawide, with a frame down the middle.
How far should you sit from a 24 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 24 inch screen fills at each distance. It feels very wide at 18 to 20 in46 to 51 cm, wide at 24 to 28 in61 to 71 cm and ideal at 32 in81 cm.
Which resolution suits a 24 inch monitor?
Higher resolution looks sharper but makes text smaller, so you need display scaling. At 24 inches, 1920 × 1080 gives 92 PPI and 3840 × 2160 gives 184 PPI. The table shows the Windows scaling each needs.
At this size, 1920 × 1080 looks clear, 2560 × 1440 looks crisp and 3840 × 2160 looks very sharp. 1920 × 1080 works at 100% scaling, while 2560 × 1440 needs 125% and 3840 × 2160 needs 200%.
Sit farther away than the last column and you will not see single pixels. See every resolution in the chart.
How does a 24 inch monitor compare with other sizes?
The next size up, the 25 inch monitor, has 9% more screen area. The next size down, the 23.8 inch monitor, has 2% less screen area. Area grows with the square of the diagonal, so a few inches feel bigger than they sound.
Either way, that is a small step.

The AOC 24G50F and AOC 24G51F are the thinnest in the table, at 1.4 in (3.6 cm) deep without the stand. On an arm, that is close to all the depth it takes, while a stand needs more desk.
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.
