EXACT aspect ratio question... (1 Viewer)

[John Parris]

16:9 is 1.78:1
1366x768 (native resolution of my projector) is close to that...
1280x768 (standard widescreen monitor resolution) is closer to 1.67:1

I'm going to start making my screen today, but as I measured I realized this discrepency...

What is the exact ratio I should measure by?

If you already have your projector, can you shine it on a wall and take measurements? If that isn't possible, you might want to check out the projection calculator for your projector at projectorcentral.com.

FWIW my Sony HS10's resolution is 1366x768, and it fits my 92"x52" screen nicely. Based on that, I'd go for 1.78:1.

I wouldn't go by the resolution for determining aspect ratio since the projector could easily be using non-square pixels. Shouldn't the basic specs for the projector tell you if it's 4x3 or 16x9??
