AV calculator
Screen size, projector throw, contrast, and audio coverage — to the ANSI/AVIXA standards. Deterministic numbers you can put straight on a bid and defend to a client.

What the AV calculator works out
Screen size
Image size from the farthest viewer and content type — to ANSI/AVIXA sizing standards.
Projector throw
Throw distance and lens range for the screen and room you specify.
Contrast targets
The contrast ratio your content needs vs. the ambient light in the room.
Audio coverage
Speaker coverage and SPL math so the back row hears what the front row does.
Standards-based
ANSI/AVIXA V202.01 and friends — deterministic, not vibes.
Bid-ready
Numbers you can put straight on a scope sheet and defend to a client.
How it works
- 1
Describe the room
Farthest viewer, content type, ambient light, screen or speaker placement.
- 2
Run the math
Screen size, throw, lens, contrast, and coverage compute to the standard.
- 3
Put it on the bid
Defensible, cited numbers — no guessing, no “looks about right.”
AV calculator — FAQ
How do I calculate the right projection screen size?
AVIXA’s sizing standard ties minimum image height to the distance of the farthest viewer and the content type (basic viewing vs. detailed analytical content). The AV calculator applies the standard and returns the screen size for your room.
How do I find projector throw distance?
Throw distance is the screen width times the lens throw ratio. Enter the screen and room and the calculator returns the throw distance and the lens range that fits.
How do I know if my audio covers the room?
Coverage depends on speaker dispersion, placement, and SPL loss over distance. The calculator works out coverage and level so the back row hears what the front row does.
Is the AV calculator free to use?
It’s open to every crew. It’s the same standards-based engine inside Wavemist’s bidding platform, used standalone here.
