Our school purchased a used HD6K to be used in the gym for film nights.
The expected audience is about 200 people.

We need to buy a screen to match the projector. What is the optimal size and gain for the screen?
We would like to have it large in order to give a real theatre effect. The distance at which the projector will be placed from the screen cannot exceed 31'.

Thanks for any suggestions.

Edit: Forgot to mention that the lens is 1.8-2.6:1 zoom lens.

You bought the original HD6K, without the -M, so with the Cermax Xenon lamp? That one isn't in the online calculator anymore, so if some-one can say wether the throw is the same or similar to the Mercury lamp version, that one could be used, instead: http://www.christiedigital.com/en-u.../throw-distance-calculator/pages/default.aspx.

If that is the case you could go between 233 and 300 inches wide, at maximum throw.
