## Will it fit?

**On furniture.** Its pedestal needs a furniture top at least **18.4 in** wide (14.4 in plus 2 in each side) and 11.4 in deep. On its own stand the screen's center sits 16.6 in above the furniture top, so a **23 in** high stand puts it at a typical seated eye height of 40 in. 

**On the wall.** The TV uses VESA 300x200 mm and weighs 35.3 lb without its stand. Allow about 50.2 × 29.9 in of clear wall (1 in each side). It will stand off the wall by its own 1.6 in plus the mount's depth, which the mount's own spec sheet gives. See [how to choose a wall mount](/tv-wall-mount-types/).
