What to know

Diagonal sizes undersell the difference: area grows with the square of the diagonal, so going from 65 to 75 inches (15% longer diagonal) adds 33% more picture.

If your seat is fixed, pick the size whose recommended range includes your viewing distance. Measure from your eyes to the screen, not from the sofa to the wall.
