How to choose the right TV size

The right screen size is about how much of your field of view the picture fills. The Society of Motion Picture and Television Engineers suggests the screen should fill about 30 degrees of your view for comfortable everyday watching. For a cinema feel, THX recommends closer to 40 degrees. The calculator measures that angle from your seating distance and suggests the closest standard size.

Modern 4K and 8K screens have such fine pixels that you can sit much closer than the old rules for HD sets suggested, so most people are happiest going one size bigger than they first planned.

How high should you mount a TV?

Aim for the center of the screen to sit at your eye level when seated, usually about 42 inches (107 cm) from the floor for a sofa. Mounting a TV high above a fireplace forces you to tilt your head back, which gets uncomfortable over a long film. If you must go high, use a tilting or pull down mount so you can angle the screen toward you.

Test with cardboard. Cut a piece of cardboard to the screen size, or tape the outline on the wall, and sit in your usual spot. It is the fastest way to see if a size feels right before you buy.

Fitting a TV into your living room design

A large black screen can dominate a room, so balance it with art, shelving or a gallery wall, and choose a media console at least as wide as the TV. Plan the whole layout with our rug size calculator and wall art size calculator, and see our living room layout ideas for inspiration.

Frequently asked questions

What size TV for an 8 foot viewing distance?
About 65 inches for everyday viewing, or 75 inches if you want a cinema feel for movies and sport.
How far should I sit from a 65 inch TV?
Roughly 7 to 8.5 feet (2.1 to 2.6 m). With a 4K TV, sitting at the closer end gives a more immersive picture without visible pixels.
Is a bigger TV always better?
Up to a point. If the screen fills much more than 40 degrees of your view, you will have to move your eyes and head to follow the action, which gets tiring.
How high should a TV be mounted?
The center of the screen should be at seated eye level, usually about 42 inches (107 cm) from the floor.
Is this TV size calculator free?
