Sony XR42A90K VESA pattern and wall-mount specs
The Sony XR42A90K — the 42-inch A90K OLED — uses a 200 x 200 mm VESA pattern and weighs 29.3 lb (13.3 kg) without its stand, according to Sony's product page. Any wall mount whose range covers 200 x 200 and is rated for at least 29.3 lb will hold it.
Mount checklist for the XR42A90K
- 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: 29.3 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
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 29.3 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' 42-inch TVs: Samsung OLED S90H (18.3 lb, 200 x 200 mm). All share this TV's pattern, so a mount chosen for one would fit them too.
Among Sony's 46 models here, 5 use 200 x 200 mm (13%); Sony's most common pattern is 300 x 300 mm. Sony's page doesn't state the model year.
Other sizes in the Sony A90K OLED line
The pattern is not the same across the line: it changes from 200 x 200 mm on the 42" to 300 x 300 mm on the 48". A mount bought for one size is not automatically right for another.
| Model | Size | VESA (mm) | Weight |

| XR48A90K | 48" | 300 x 300 mm | 29.6 lb |

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.
