Compatibility guides

The specifics behind the checker — VESA patterns, weight ratings, and which desks a clamp can (and can't) grip.

VESA is the four-hole square pattern on the back of most monitors. What the sizes mean, and how to find yours.

100x100mm is the default VESA size for most 24-34" monitors, and nearly every arm supports it. Verified examples inside.

49"+ displays and giant curved screens often use 200x200 or 200x100 VESA and need heavy-duty mounts. What to know.

27" monitors are the easy case — 100x100 VESA, ~3-7kg, and a standard gas-spring arm handles them. Verified weights inside.

32" monitors run 5-10kg and some 4K/curved models push a standard arm. When you need heavy-duty. Verified inside.

34" ultrawides are ~5-8kg but wide, so leverage and arm reach matter as much as the weight rating.

49" super-ultrawides are 9-15kg and often exceed standard arms. What rating you actually need, verified per model.

Apple displays ship with no VESA holes. You choose the VESA-adapter version at purchase, or you're stuck with the stand.

Curved 49"/57" monitors weigh 12-15kg+ and exceed typical arms. The rating you need, and the models that need a specialised mount.

Some monitors have no VESA holes. Clamp-on adapter brackets exist but have real weight limits — when to use one, when to give up.

Clamp jaws grip a limited thickness. Butcher block and thick tops can exceed it — how to check clamp range and when to use a grommet.

Usually no. A clamp concentrates stress that can crack tempered glass, and most makers prohibit it. Your safe options.

IKEA tops range from solid to hollow honeycomb. The hidden trap: clamping a Linnmon-style board without a backing plate.

Arm ratings are a range, not a single number, and gas springs can be optimistic. How we read ratings, and the 1.2x margin we apply.
