    How far would a projector have to be away to fill the screen size 153 x 153cm??

    Thanks

    First question would have to be what projector, second question why the square aspect ratio? With any projector you'll either fill the width but not the height or fill the height and have the image sides over hanging the screen edge.

    153 cm is about 5.5 feet, so base it in on a 6 foot screen projector would have to be about 9 feet away, (principle is 1.5 times size of screen)

    Matt, I might have missed something here but I couldn't see where dave1de mentioned which projector he is using so the throw distance to fill his screen would depend on the throw ratio of his projector lens. For the 1.5 time size, would you be refering to seating distance rather than throw distance?

    Hi Guys,

    I hope that this PDF document attached is of help when working out distances. It is the 'rule of thumb' that I offer .

    Regards :)
