Bigger is not always better. Enter how far you sit from the screen and see the screen size that suits comfortable, cinematic or immersive viewing.
How it works
Home cinema guides describe the screen by how much of your field of view it fills. About 30 degrees is comfortable for long viewing, around 36 degrees feels cinematic, and 40 degrees is very immersive. The calculator works out the screen width for each angle and converts it to a diagonal.
Example: sitting 10 feet (120 inches) away, a cinematic 36 degree view suggests a diagonal of about 89 inches on a 16:9 screen.
Frequently asked questions
Can I go bigger with a 4K projector?
Yes. Sharper 4K images let you sit closer or choose a larger screen without seeing pixels, so the immersive size is a fair choice.
Which size should I choose?
For mixed use in a living room, the comfortable size is a safe pick. For a dedicated dark room, the cinematic or immersive size works well.
Does room size matter?
Yes. Check that the screen width fits your wall and that the throw distance for your projector fits the room.
