Sony XR48A90K VESA pattern and wall-mount specs
The Sony XR48A90K — the 48-inch A90K OLED — uses a 300 x 300 mm VESA pattern and weighs 29.6 lb (13.4 kg) without its stand, according to Sony's product page. Any wall mount whose range covers 300 x 300 and is rated for at least 29.6 lb will hold it.
Mount checklist for the XR48A90K
- Pattern: 300 mm wide by 300 mm high (11.8 x 11.8 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: 29.6 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 Sony 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 300 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 300 tall, because some budget mounts stop at 300 x 300. At 29.6 lb it is a two-person lift onto the mount, and well inside the rating of mainstream fixed and tilting mounts; on a full-motion arm, check the rating at full extension.
Closest in weight among other brands' 48-inch TVs: Samsung OLED S85H (27.1 lb, 300 x 200 mm); LG OLED evo C6 (32.8 lb, 300 x 200 mm); Samsung OLED S90H (23.4 lb, 300 x 200 mm). None of them shares this TV's pattern — a reminder that size and weight don't predict the holes.

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. At this size 4K looks sharper than 1080p only from 6 ft 3 in or closer; beyond that, 20/20 eyes cannot tell the two apart. The 48-inch size page has the full table and every model at this size.
