Hi Product Hunt! I made DisplayMath because "55 or 65?" is a question about how much wall the picture covers and how far away you sit, and every calculator I found answered it with a table. So this one draws. Add any two screens (about 800 presets, or type your own) and they land on top of each other at true scale. Switch to your seat and it shows what each one fills of your view, how sharp it is from there, and where the "cinema" seat is. On an iPhone, tap View on your wall and the actual-size screen stands in your room, no app to install. The video is my own living room: a 97" over the 77" I already have. Free, no signup, nothing to install. I am here all day, ask me anything, and if you find a screen missing from the presets tell me and I will add it.

55 to 65 inches means about 40% more picture, so we drew the comparison

I built DisplayMath. We have put together a visual guide to the measurements that a diagonal hides.

For a flat 16:9 picture, 55 in is about 121.8 68.5 cm and 65 in is about 143.9 80.9 cm. That is 39.7% more picture area, before the bezel and stand. From the same 2.5 m seat, the horizontal view changes from about 27.4 to 32.1 .

The guide separates physical fit from the view at your seat. Check the exact product's outside dimensions before buying.
