How big is a 38 inch ultrawide monitor with the stand?
Stands add height and depth, and frame widths vary. Here are the real measurements of popular 38 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 three 38 inch ultrawide monitors from BenQ, Dell and ViewSonic. Their bodies are 35.2 in89.4 cm to 35.3 in89.7 cm wide, or 0.1 in0.3 cm to 0.2 in0.6 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 U3824DW is the thinnest at 4.0 in10.2 cm deep. At the other end, the BenQ EW3880R is 5.5 in13.9 cm deep.
Weights run from 17.4 lb7.9 kg for the ViewSonic VP3881a to 21.61 lb9.8 kg for the BenQ EW3880R. A monitor arm rated for 22 lb10.0 kg or more covers the weight of every model here.
With their stands, the makers list heights of 17.5 in44.5 cm to 19.6 in49.8 cm, so measure under any shelf. On their stands, they take 9.9 in25.1 cm to 11.8 in30.0 cm of desk depth.
All three share one VESA pattern, 100 x 100 mm, so one arm pattern covers them all.
Will a 38 inch ultrawide 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 38 inch screens side by side need at least 70.2 in178.2 cm (178.2 cm70.2 in) of desk width for the screens alone. Three need 105.2 in267.3 cm (267.3 cm105.2 in). Add the frame widths from the table above.
That screen is about as wide as two 20 inch monitors side by side, without the frames between them.
How far should you sit from a 38 inch ultrawide monitor?
Desk screens are usually viewed from 20 to 30 in (50 to 75 cm). The table shows how much of your view a 38 inch screen fills at each distance. It feels very wide at every distance in the table, from 18 to 32 in46 to 81 cm, so expect to turn your head.
Which resolution suits a 38 inch ultrawide monitor?
Higher resolution looks sharper but makes text smaller, so you need display scaling. At 38 inches, 3840 × 1600 gives 109 PPI and 3840 × 1600 gives 109 PPI. The table shows the Windows scaling each needs.
At this size, 3840 × 1600 looks clear. It needs 125% Windows scaling, so text stays a readable size.
Sit farther away than the last column and you will not see single pixels. See every resolution in the chart.
How does a 38 inch ultrawide monitor compare with other sizes?
The next size up, the 43 inch monitor, has 54% more screen area. The next size down, the 34 inch ultrawide monitor, has 20% 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 very big 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.
