How the Calculation Works
THX / SMPTE Standards
We use the same viewing angle standards used in professional cinema design — 1.5x to 2.5x the screen diagonal for optimal immersion.
Back Row is the Limit
The farthest seat determines the minimum screen size. We calculate based on your last row so every seat in the house gets a great view.
