TV Size & Distance Calculator

Choose the right TV size for your room and find a comfortable viewing distance before you buy, mount, or rearrange your setup.

TV Size & Distance Calculator helps you plan a screen around your actual space. Enter your sofa distance to get a recommended TV size range, or enter a TV diagonal to estimate a comfortable seating distance. You can also calculate physical screen dimensions and check whether a TV will fit on your wall.

TV SIZE FROM VIEWING DISTANCE

Know how far your sofa is from the screen? Enter your viewing distance and get:

• Recommended TV size range
• A balanced sweet-spot size
• Conservative, mixed TV, and immersive viewing preferences
• Quick comparisons for common TV sizes

This makes it easier to compare 55-inch, 65-inch, 75-inch, and other screen sizes based on your room instead of guessing in the store.

VIEWING DISTANCE FROM TV SIZE

Already know the TV size you want?

Enter the screen diagonal to calculate a comfortable viewing-distance range. Compare different viewing preferences to see how moving closer or farther away changes the viewing experience.

Useful when planning:
• Living rooms
• Bedrooms
• Home theater setups
• Gaming rooms
• New TV purchases
• Furniture placement

TV SCREEN DIMENSIONS

A TV's advertised diagonal does not tell you its exact width and height.

Use the screen dimensions calculator to convert a TV diagonal and aspect ratio into the physical screen rectangle. See the estimated screen width and height before measuring your wall, cabinet, stand, or media unit.

WALL FIT CALCULATOR

Check whether a TV will fit your available wall space before installation.

Enter:
• Wall width and height
• TV diagonal
• Desired margin
• Screen aspect ratio

The wall fit tool shows whether the screen fits and how much space remains around it. This is useful when comparing larger TVs or checking a setup before wall mounting.

VIEWING PREFERENCES

There is no single perfect TV distance for every person or room. Choose a preference that matches how you like to watch:

• Conservative — a more relaxed viewing angle
• Mixed TV — balanced for shows, sports, and films
• Immersive — a larger field of view for a more cinematic feel

Recommendations are based on common viewing-angle guidance and are intended as a practical starting point. Personal comfort, room layout, content, eyesight, and TV design can affect the final setup.
