Questions about 40″ vs 85″
Which size should I buy for my room?
Match the diagonal to your seating distance — our viewing distance calculator turns a comfortable distance into a recommended size range for any screen.
Is 85″ too big if I sit close?
If you sit closer than about 2.59 m, a 85″ screen can feel oversized — the 40″ option keeps a comfortable field of view at shorter distances.
Why compare area instead of diagonal?
Area is what you actually see. Two screens with the same diagonal but different aspect ratios can differ in area by 10% or more, which diagonal alone hides.
