TV Mounting Height Calculator

Your details

The diagonal screen size printed on your TV box. This is always measured in inches regardless of the unit switch.
in
Measure from the floor to your eyes while seated in your usual viewing spot. The average is about 42 in (107 cm).
in
Horizontal distance from your eyes to the TV screen surface. 8 ft (244 cm) is a common living-room distance for a 55-inch TV.
in
How many degrees above horizontal your eyes look toward the TV center. 0 deg = pure eye level. 10-15 deg is comfortable for most viewers. Above 20 deg can cause neck strain over long sessions.
deg
Used to calculate the recommended viewing distance for your screen size. SMPTE 30 deg is the broadcast/cinema standard; THX 40 deg is recommended for home theater immersion.
Height of the TV stand, console, or fireplace mantle below the TV. Enter 0 if wall-mounting above nothing. The calculator warns if the TV bottom edge is too close.

Mount the center of your 55-inch TV at 58.9 in from the floor.

  • Mount the bracket so its center sits at 58.9 in from the floor. The screen bottom will be at 45.4 in, which you can mark with tape before drilling.
  • Your viewing distance of 96 in is well within the SMPTE 30-degree recommended range of 89 in.

Next stepFor fireplaces or high-mounted TVs where lowering is not possible, recline the seating so your eye level rises to match the mount height. A reclined angle of 15 to 20 degrees can restore a comfortable gaze.
