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 32.2 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.
