Which should you pick?
The 38″ ultrawide gives you more usable space — about 25% more area — which helps with multitasking and side-by-side windows. The 34″ ultrawide fits smaller desks, sits at a closer comfortable distance (40–95 cm vs 40–95 cm), and is easier to take in without turning your head.
Whatever the size, the ergonomics rule is the same: the top of the screen at or just below eye level, and the screen roughly an arm's length away. A bigger panel usually needs to sit a little further back.

- Is a 38-inch ultrawide worth it over a 34-inch?
- You get about 25% more area and more width at the same sharpness (~110 PPI). Great for heavy multitasking if your desk is deep enough.
- How far back should an ultrawide sit?
- About 40–95 cm; with wide panels, sitting a little further lets you take in the edges without turning your head.
- Do I need a bigger desk for a 38-inch?
- It's nearly 89 cm wide, so a deep, wide desk helps — both to fit the panel and to allow a comfortable viewing distance.
