Which should you pick?

The 42″ gives you more usable space — about 72% more area — which helps with multitasking and side-by-side windows. The 32″ fits smaller desks, sits at a closer comfortable distance (48–95 cm vs 42–95 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.

FAQ

Is a 42-inch monitor too big for a desk?
It's 72% more area than a 32″ and about 93 cm wide, so it only works on a deep desk viewed from roughly 42–95 cm back. Many use 42″ 4K panels as productivity monitors.
Is a 42-inch 4K sharper than a 32-inch 1440p?
Yes — about 105 PPI versus 92 PPI here, so a 4K 42″ can look crisper despite its larger size.
How far should I sit from a 42-inch?
Around 42–95 cm, ideally toward the far end so you can take in the whole panel without turning your head.
