Most people buy a TV that’s either comically small for the room or so big the front row gets motion sickness. The right size is a simple function of viewing distance — and our free TV size calculator applies the industry formula to your room, then the TV size calculator tells you exactly where to mount it.

What the TV Size Calculator Tells You (Specifications)

• Inputs: viewing distance in feet, and main use (cinematic / everyday / casual).
• Ideal screen size — viewing distance in inches divided by 2 for everyday viewing (1.6 for cinema feel, 2.5 for casual), rounded to the nearest standard size: 43, 50, 55, 65, 75, 77, 85 or 98 inches.
• Screen width in inches, so you can check it against your wall or console.
• Placement advice — screen center at ~42″ from the floor (seated eye level), or a console recommendation for very large screens.

How to Use It — Step by Step

1. Measure viewing distance — from where your eyes sit to where the screen will hang, in feet.
2. Choose your main use. Movie nights: cinematic. Daily mix: everyday. Background viewing: casual.
3. Hit calculate and note the recommended size and width.
4. Check the fit — tape the width on your wall with painter’s tape and live with it a day before buying.
5. Plan the wall with our gallery wall calculator if the TV shares a wall with art.

Designer Tips for TV Placement

• The #1 mistake is mounting too high. Screen center at seated eye level (~42″) — above the fireplace is almost always too high.
• Bigger isn’t always better. Sit closer to a smaller screen for immersion without neck strain.
• Hide it in luxury rooms. Frame-style TVs or artwork mode keep the screen from dominating the design.
• Mind the glare — never place the screen directly opposite an uncovered window.
