TV size and viewing distance calculator
Find out how far your sofa should be from the TV, what size suits your room, how wide the TV unit should be, and how high to mount it.
Estimates only, for planning. Measurements and quantities for your home are confirmed on site.
How we calculate it
A comfortable viewing distance for HD and 4K TVs is roughly 1.5 to 2.5 times the screen diagonal. Closer feels immersive, further feels relaxed. Screen width and height are worked out from the diagonal for a standard 16:9 TV.
We suggest a TV unit at least a foot wider than the screen so the TV does not look perched.
Mounting tips
For seated viewing, keep the centre of the screen near eye level, about 42 inches (107 cm) from the floor. Plan concealed conduits and sockets behind the console before the wall is finished.
