TV Viewing Distance & Mounting Height Calculator

Find the right TV size, viewing distance, and screen mounting height for your room. Enter the measurements you already know, and the calculator will help determine the rest using TV aspect ratio, resolution, viewing posture, eye level, room depth, and horizontal Field of View.

Find the Right TV Size

Enter your existing viewing distance to estimate a practical TV diagonal for your room and preferred viewing experience.

Calculate Viewing Distance

Select your TV size to calculate a recommended eye-to-screen distance based on horizontal Field of View.

Set the Mounting Height

Calculate the screen center height using your viewing posture, eye level, and distance from the TV.

Check Room Fit and Ergonomics

Review Field of View, neck ergonomics, screen dimensions, rear-wall clearance, and the physical limits of your room.

How to Use the Calculator

Choose Your Units and Viewing Posture

Select Inches, Centimeters, or Meters, then choose how you normally watch TV: Sofa, Bed, Bar stool, or Standing.

Select the TV Format

Choose the TV aspect ratio and resolution. These values affect the available TV size presets, screen dimensions, and detail visibility.

Enter What You Already Know

Start with either the TV diagonal or the viewing distance. You do not need to enter both.

Choose What to Calculate

Use Optimal TV to calculate TV size from your viewing distance. Use Optimal Distance to calculate viewing distance from the selected TV size. Use Mount to calculate the recommended screen center height.

Refine the Room Setup

Enable Back wall consideration to add the room depth and limit the maximum possible viewing distance. Enable Lock distance with TV diagonal to keep TV size and viewing distance synchronized.

Review the Results
