Sony K55XR70M2 VESA pattern and wall-mount specs
The Sony K55XR70M2 — the 55-inch BRAVIA 7 II — uses a 300 x 300 mm VESA pattern and weighs 40.6 lb (18.4 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 40.6 lb will hold it.
Mount checklist for the K55XR70M2
- 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: 40.6 lb without the stand. Mounts are rated by maximum load; a mount rated 50 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 40.6 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' 55-inch TVs: LG Gallery TV LX7 Mini LED (41 lb, 400 x 300 mm); Samsung OLED S95H (35.9 lb, 300 x 200 mm); Samsung The Frame Pro LS03HW (33.1 lb, 200 x 200 mm). None of them shares this TV's pattern — a reminder that size and weight don't predict the holes.
Same mount, different model: Sony's K55XR50 (BRAVIA 5, 2025) also uses 300 x 300 mm and weighs 39 lb. A mount that suits the K55XR70M2 suits it too, which is handy if you are choosing between them.
Among Sony's 46 models here, 20 use 300 x 300 mm (51%), the most common Sony pattern. It is a 2026 model, so the specs above come from a current listing.
Other sizes in the Sony BRAVIA 7 II line
The pattern is not the same across the line: it changes from 200 x 200 mm on the 50" to 300 x 300 mm on the 55", and it changes from 300 x 300 mm on the 75" to 400 x 400 mm on the 85", and it changes from 400 x 400 mm on the 85" to 600 x 400 mm on the 98". A mount bought for one size is not automatically right for another.

Where to sit
A 55-inch 16:9 screen is 47.9 in wide and 27 in tall. It fills the SMPTE 30° view from 7 ft 5 in and THX's 40° cinema view from 5 ft 6 in. At this size 4K looks sharper than 1080p only from 7 ft 2 in or closer; beyond that, 20/20 eyes cannot tell the two apart. The 55-inch size page has the full table and every model at this size.
