Full Version: Double checking screen size
I plan on doing a 120" screen, and just want to double check my math before I buy. If I figure correctly (a2 + b2=c2; 2=squared), then a 120" screen at a 4:3 ratio should be 8' by 6', or 96" by 72" to give a 120" diagonal. Thanks!
That is correct. Aren't you glad you payed attention in geometry class?
