    Hi, long time reader first time poster at the av forums,

    looking to make a screen as i understand that is the cheapest option, I know there are a few threads about this but i can't find cloth large enough. The biggest width iv'e found is 54" when i am looking for about 90"ish

    I take it stiching two or more sections together would be pointless? So does anyone know where there are larger areas of blackout cloth avail?

    Tia!

    Thats one big screen!! Most peoples aren't even that long!

    I have just ditched my blackout cloth screen (stretched over a frame) for an MDF painted one. If you cannot get suitable sized fabric, it would easier to join two or more sheets of MDF and smooth the join with filler. I have filled screw holes on mine and once painted they are untraceable.

    Good luck with the hunt for fabric that size, someone may know of an industrial supplier that can get you the size you want (unlike my local fabric shop!)

    Just so i can clarify, you need a screen that is 90" high and ~160" (16-9 ratio)?

    You only need the size to be equal to a recognised screen ratio - 16:9 being the most usual, and 4:3 being the other. 2.35:1 screens are quite rare in home cinema.

    If you have a screen that's not one of those sizes, you end up with a lot of unused space above/below the image, and/or notice the light spill, or where it finishes. You'll be better off with a screen that is a pukka screen ratio, so the MDF route might be your best option if you can't find cloth at the size you want.

    A wall painted with a few good coats of matt white paint will be almost as good as a proper screen, and you have the size you want then. :)

    What projector will you be using? If you make the image too large, it might be very dark, as the amount of light needed increases 4-fold as you go larger - i.e, twice the size needs 4 times the light to keep the brightness the same.

    HTH

    Yes - I used speaker brackets with some 6mm mdf, and they work fine. :)

    Have you seen my DIY links for them?
