TV Screen Size Calculator

Work out the best TV size for your room from your seating distance and available wall space, with exact screen dimensions.

Space between windows, doors or corners.
For speakers, decor or breathing room.

How the TV size calculator works

The calculator turns your seating distance into a recommended diagonal using viewing-angle guidelines (about 30° to 40° field of view). For 1080p it caps the size so pixels stay invisible from your seat. It then checks the actual screen width of each standard TV size against your available wall width (minus the margins you set), so you only see sizes that fit.

Screen dimensions assume a 16:9 screen. Real TVs add roughly 0.5–1" of bezel, and stands add height, so leave a little extra room.

FAQ

What size TV should I get for my living room?

Measure from your seat to the wall. For 4K, a diagonal of roughly your distance in inches divided by 1.6 (comfortable) up to divided by 1.2 (cinematic) works well. The calculator also checks it fits your wall.

Is a bigger TV always better?

Not if it is too big for your seating distance or wall. Too large a screen for the distance means more head and eye movement. Check both distance and wall width.

How wide is a 75 inch TV?

The screen of a 75" 16:9 TV is about 65.4" wide and 36.8" tall, plus the bezel.
