Use this 38 inch ultrawide monitor dimensions calculator to find the approximate width, height, diagonal, and desk space for a 21:9 ultrawide display. The listed monitor size is the diagonal screen measurement, not the full outside product size. The bezel, stand, arm mount, and cable clearance can add extra width, height, and depth depending on the model.

Use this chart when you need the approximate screen dimensions for a 21:9 38 inch ultrawide monitor. These values describe the viewable screen, not the full body of the monitor.
| Measurement | Inches | Centimeters |
|---|---|---|
| Screen diagonal | 38 in | 96.5 cm |
| Screen width | 34.9 in | 88.7 cm |
| Screen height | 15 in | 38 cm |
How Wide Is a 38 Inch Ultrawide Monitor?
A 38 inch ultrawide monitor with a 21:9 aspect ratio is about 34.9 inches wide, or 88.7 cm wide. This is the screen width only. When checking whether it fits your desk, monitor arm, or workstation, leave room for the bezel and side clearance.
How Tall Is a 38 Inch Ultrawide Monitor?
The screen height of a 38 inch ultrawide monitor is about 15 inches, or 38 cm. The full height can be larger when the monitor is placed on its stand.
38 Inch Ultrawide Monitor Viewing Distance
A practical viewing distance for a 38 inch ultrawide monitor is roughly 3.2 to 5.1 feet. For monitors, the best distance also depends on text size, resolution, desk depth, and whether you use the display for work, gaming, or editing.
How the Size Is Calculated
This page uses a 21:9 ultrawide aspect ratio. To calculate width and height from the diagonal, the calculator splits the diagonal across 21 units of width and 9 units of height.
width = diagonal x 21 / sqrt(21^2 + 9^2) height = diagonal x 9 / sqrt(21^2 + 9^2) Will a 38 Inch Ultrawide Monitor Fit?
Compare the screen width of 34.9 inches with the available space on your desk, monitor arm, or multi-monitor setup. The actual body can be slightly wider than the screen, so checking the manufacturer dimensions is still important before buying or mounting.
If you are comparing nearby sizes, check 34 inch ultrawide monitor dimensions and 45 inch ultrawide monitor dimensions to see how much width and height change from one screen size to the next.
Screen Area
The viewable area of a 38 inch ultrawide monitor is about 523 square inches, or 3,373 square centimeters. Screen area grows quickly as diagonal size increases, so a larger display can feel much bigger than the diagonal number alone suggests.

Best Use Guide
The best screen size depends on how close you sit, what you watch or work on, and how much physical space you have. Use these practical notes as a starting point before checking exact product dimensions.
| Use Case | What to Check | Why It Matters |
|---|---|---|
| Productivity work | Desk width and text clarity | A larger monitor is useful only if text and window layout stay comfortable. |
| Gaming | Distance, refresh rate, and field of view | Closer viewing can feel more immersive, but too large can make edges harder to scan. |
| Monitor arm setup | Weight, VESA mount, and arm reach | The screen dimensions are not the same as the full product size or mount requirements. |
| Small desks | Depth, keyboard space, and side clearance | A screen can technically fit but still feel too close or visually overwhelming. |
Common Mistakes to Avoid
- Do not treat the advertised 38 inch size as the screen width. It is the diagonal measurement.
- Do not use screen dimensions as final product dimensions. The bezel, stand, and frame can add extra size.
- Do not compare diagonal sizes across aspect ratios without checking width and height. Ultrawide screens can be much wider than they sound.
- Do not forget clearance for cables, wall mounts, speakers, monitor arms, or nearby furniture.
Desk Space Notes
For a monitor, width is usually the most important fit measurement. Leave extra room for the stand base, monitor arm movement, speakers, laptop placement, and any second display you plan to use.
Ultrawide monitors can replace a dual-monitor setup for many workflows, but they need more horizontal desk space. A 21:9 display also feels different from a standard 16:9 monitor because it is wider for the same diagonal size.
