Room planner
Plan the room first
Screen size, throw distance, light and sound. A guide to what fits before you buy anything.
Screen size
By seat distance
For 4K. With 1080p, sit a little further back.
| Seat to screen | Screen (16:9) | Picture width |
|---|---|---|
| 2.5m | 100 inch | 2.2m |
| 3m | 110 inch | 2.4m |
| 3.5m | 120 inch | 2.7m |
| 4m | 135 inch | 3.0m |
| 4.5m | 150 inch | 3.3m |
General guidance.
Throw
How far back the projector goes
Throw ratio times picture width gives the distance from lens to screen.
| Projector | Throw ratio | For a 2.2m wide picture |
|---|---|---|
| Ultra short throw | 0.25 | About 25cm from the wall |
| Short throw | 0.5 | About 1.1m |
| Standard | 1.2 | About 2.6m |
| Long throw | 1.4 to 2.2 | 3.1m to 4.8m |
General guidance. Check the throw for the exact projector.
Light and sound
Four things to check
Light
Where the sun comes in, and when you watch.
Echo
Clap your hands; a long ring means panels.
Seats
One row or two, and how far back.
Power
Where the sockets are and what happens in a cut.
Survey
Book a room survey
Your area, the room and when you watch most.
