Will it fit?
On furniture. Its pedestal needs a furniture top at least 19.3 in wide (15.3 in plus 2 in each side) and 10.3 in deep. On its own stand the screen’s center sits 16.3 in above the furniture top, so a 24 in high stand puts it at a typical seated eye height of 40 in.
On the wall. The TV uses VESA 200x200 mm and weighs 39 lb without its stand. Allow about 50.3 × 29.8 in of clear wall (1 in each side). It will stand off the wall by its own 1.1 in plus the mount’s depth, which the mount’s own spec sheet gives. See how to choose a wall mount.
