Samsung QN48S90HAEXZA VESA pattern and wall-mount specs
The Samsung QN48S90HAEXZA — the 48-inch OLED S90H — uses a 300 x 200 mm VESA pattern and weighs 23.4 lb (10.6 kg) without its stand, according to Samsung's product page. Any wall mount whose range covers 300 x 200 and is rated for at least 23.4 lb will hold it.
Mount checklist for the QN48S90HAEXZA
- Pattern: 300 mm wide by 200 mm high (11.8 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 rectangular pattern outside the square Part F table, which is normal for current TVs; screws are usually M6 or M8 at this size, but the manual is the authority.
- Weight: 23.4 lb without the stand. Mounts are rated by maximum load; a mount rated 30 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
300 x 200 mm sits in the middle of the range most "medium to large" mounts cover — check that the mount's largest pattern is at least 300 wide and 200 tall, because some budget mounts stop at 300 x 300. At 23.4 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' 48-inch TVs: Sony BRAVIA 6 OLED (27.6 lb, 300 x 200 mm); Sony A90K OLED (29.6 lb, 300 x 300 mm); LG OLED evo C6 (32.8 lb, 300 x 200 mm). 2 of them share this TV's pattern.
Samsung's other 48-inch models here — OLED S85H (300 x 200 mm, 27.1 lb) — all share its pattern, so the mount question is only about weight.
Among Samsung's 78 models here, 9 use 300 x 200 mm (12%); 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

Where to sit
A 48-inch 16:9 screen is 41.8 in wide and 23.5 in tall. It fills the SMPTE 30° view from 6 ft 6 in and THX's 40° cinema view from 4 ft 9 in.
