Use my Screen Dimension Calculator. It includes Sharp 9000 throw distance formulas.
I just clicked on the link and it says "page not found". Anyone know a good source for a Sharp 9000 throw distance calculator?
I had nothing else to do this evening (god my life is so dull!) and so I downloaded the manual for the XV-Z9000 from Sharp's website and did some calculatin'.

A screen with an aspect ratio of 16:9 and a width of 102" will have a height of 57.375" and a diagonal measurement of 117".

Using Sharp's maximum projector distance formula of

Lmaxfeet = (0.0524x - 0.0447) * 3.28

where x is the screen diagonal measurement in inches, we get ((0.0524 * 117) - 0.447) * 3.28 = 18.64 feet.

Using Sharp's minimum projector distance formula of

Lminfeet = (0.0436x - 0.0447) * 3.28

where x is the screen diagonal measurement in inches, we get ((0.0436 * 117) - 0.447) * 3.28 = 15.27 feet.

So, if you want to have a 102" wide screen with a 16:9 aspect ratio, you will need to have a projector lens-to-screen distance of between 15'-3" and 18'-8".

I've had some web hosting problems the last 2 weeks. I moved the calculator and changed the link tonight. Clicking on the link now should take you to the calculator. Sorry for the trouble.
Scott,

The manual is for an XV-Z7000U, an LCD projector. I wonder if the throw distance is the same as for the 9000?

Does it only do 4:3 screens? I'm having a hard time following it but I'm looking for a calculator for throw distance on a 16:9 screen for the Sharp 9000.

The left side of the spreadsheet is for 16:9. The right side is for 4:3. Enter values in the gray boxes and all other values will be calculated for you automatically.
Yikes! I wanted to have a 100" 16:9 perf screen, because I read that going below this size will introduce moire effects due to the perforations. I absolutely cannot have the projector back more than 12 feet from the screen. What will happen?
Clouseau2, you'll have to get a smaller screen (without perforations if moire is a problem) or a projector with a shorter throw distance. Unfortunately, the Sharp is the only 16:9 DLP at the moment. More 16:9's are on their way, but they are all going to be more expensive than the Sharp.

Any other options? Is there a lens that reduces throw distance?
Both my mains and my center are going to be behind the screen, so a perf screen is a must. I can't change the distance from the projector to the screen, and according to the manual (thanks for the URL), my screen can't be wider than 84" diag. I guess I'll have to hope those moire effects won't be too bad ...
Is there possibly a shorter throw lens available for the 9000?
I spent a while with my diagrams, and if I hang the screen right on top of my fronts and over a desk, I can have a 100" diag 16:9 screen that is 14'1" away from the projector. I'll be sitting 12 feet away from the screen ...

However, now I'm worried the screen won't be HIGH enough!

Isn't this a fun process!
