Samsung QN42S90HAEXZA VESA pattern and wall-mount specs
The Samsung QN42S90HAEXZA — the 42-inch OLED S90H — uses a 200 x 200 mm VESA pattern and weighs 18.3 lb (8.3 kg) without its stand, according to Samsung's product page. Any wall mount whose range covers 200 x 200 and is rated for at least 18.3 lb will hold it.
Mount checklist for the QN42S90HAEXZA
- Pattern: 200 mm wide by 200 mm high (7.9 x 7.9 in). On a mount's box, both numbers must sit inside its range — "up to 400 x 400" fits this TV.
- Standard: a square Part F pattern in the VESA MIS standard, which uses M6 or M8 screws.
- Weight: 18.3 lb without the stand. Mounts are rated by maximum load; a mount rated 20 lb or more leaves no doubt, and full-motion arms should have more margin than fixed plates because the load sits further from the wall.
- Screws: use the screw length and any spacers the Samsung manual specifies. Too long can damage the panel; too short strips the insert.
- Wall: fix the mount to studs or masonry with the hardware the mount maker supplies for that wall type.
What that means when you shop
A 200 x 200 mm pattern is at the small end for TVs: nearly every TV wall mount covers it, including compact fixed plates and single-stud swing arms, so the deciding number is weight, not holes. At 18.3 lb this is a light TV — one person can hold it while another hooks it on, and almost any mount for its pattern is rated well above it.
Closest in weight among other brands' 42-inch TVs: Sony A90K OLED (29.3 lb, 200 x 200 mm). All share this TV's pattern, so a mount chosen for one would fit them too.
Among Samsung's 78 models here, 18 use 200 x 200 mm (23%); Samsung's most common pattern is 400 x 300 mm. It is a 2026 model, so the specs above come from a current listing.
Other sizes in the Samsung OLED S90H line
The pattern is not the same across the line: it changes from 200 x 200 mm on the 42" to 300 x 200 mm on the 48", and it changes from 300 x 200 mm on the 65" to 400 x 300 mm on the 77". A mount bought for one size is not automatically right for another.

Where to sit
A 42-inch 16:9 screen is 36.6 in wide and 20.6 in tall. It fills the SMPTE 30° view from 5 ft 8 in and THX's 40° cinema view from 4 ft 2 in. At this size 4K looks sharper than 1080p only from 5 ft 6 in or closer; beyond that, 20/20 eyes cannot tell the two apart. The 42-inch size page has the full table and every model at this size.
