TVProjector Throw Distance for a 150” Screen
13.1–21.8 ft
Standard-throw distance for a 150” 16:9 screen (3.99–6.64 m).
A 150-inch 16:9 projector screen is about 130.7” (332 cm) wide. Projector placement depends on the model's throw ratio (distance ÷ screen width). A typical standard-throw projector sits 13.1–21.8 ft back; a short-throw model only 4.4–8.7 ft; and an ultra-short-throw unit just 1.96–3.81 ft — practically against the wall. Always confirm the exact ratio for your projector before mounting.

Projector screens
Screen material and gain decide how bright and sharp the image looks. Choose ALR (ambient-light-rejecting) material for rooms you can't fully darken, and match the diagonal to your throw distance.

Frequently asked questions
How far should a projector be for a 150 inch screen?
A standard-throw projector needs about 13.1–21.8 ft from a 150” screen. To be exact, multiply your projector's throw ratio by the 130.7” screen width and divide by 12 to get feet.
Can I use a short-throw projector for a 150” screen?
Yes — a short-throw model sits just 4.4–8.7 ft away, and an ultra-short-throw projector only 1.96–3.81 ft (basically on a cabinet beneath the screen). These are ideal for small rooms.
What size room do I need for a 150” projector screen?
For a standard-throw projector, allow at least 21.8 ft between the lens and the screen wall, plus room for seating. Tight on space? Choose a short- or ultra-short-throw projector instead.
