Sony K55XR80 VESA pattern and wall-mount specs
Sony lists this model as VESA compatible but does not publish the hole pattern on its product page. It weighs 37.7 lb (17.1 kg) without its stand. Check the manual or measure the holes before buying a mount.
Mount checklist for the K55XR80
- Weight: 37.7 lb without the stand. Mounts are rated by maximum load; a mount rated 40 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
Without a published pattern, the mount choice starts with measuring the TV (below). At 37.7 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: Samsung OLED S95H (35.9 lb, 300 x 200 mm); LG Gallery TV LX7 Mini LED (41 lb, 400 x 300 mm); Samsung The Frame Pro LS03HW (33.1 lb, 200 x 200 mm).
Sony's other 55-inch models here — BRAVIA 2 II (300 x 300 mm, 29.1 lb), BRAVIA 3 II (300 x 300 mm, 29.4 lb), BRAVIA 5 (300 x 300 mm, 39 lb), BRAVIA 6 OLED (300 x 200 mm, 30.2 lb) — use a mix of patterns, so check the exact model before buying a mount.
Among Sony's 46 models here, this is one of the few without a published pattern. It is a 2024 model that Sony still lists; older lines are often discounted, and their mount specs don't change.
How to find the pattern on this TV yourself
- Lay the TV face down on a soft, flat surface, or measure it while it stands.
- Find the four threaded inserts on the back panel.
- Measure centre to centre between the two top holes in millimetres: that is the first number. Then top to bottom on one side: the second.
- Compare with standard patterns (100 x 100, 200 x 200, 200 x 300, 300 x 200, 400 x 200, 300 x 300, 400 x 300, 400 x 400…). A reading within a few millimetres of one of them is that pattern.
- Note the screw thread from the manual, or test-fit an M6 then M8 screw by hand — never force a screw.

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.
