About TV Sizes and Viewing Distances

Finding the right TV size depends on your room setup, viewing distance, and personal preferences. A TV that's too small won't deliver an immersive experience, while one that's too large might cause eye strain or provide poor image quality if you sit too close.

Recommended Viewing Distances
  • For 4K/UHD TVs: 1-1.5 times the diagonal screen size
  • For 1080p TVs: 1.5-2.5 times the diagonal screen size
  • For 720p TVs: 2.5-4 times the diagonal screen size

These are guidelines - personal preference and room conditions matter too.

How To Calculate TV Dimensions

For a widescreen TV with 16:9 aspect ratio, you can calculate dimensions using:

  • Width = Sin(atan(16/9)) × Diagonal Size
  • Height = Sin(atan(9/16)) × Diagonal Size

This calculator handles various aspect ratios automatically.
