Projector Distance Calculator (2021 Update)

Though it is commonly believed that a large space is needed in order to project onto large screens, today’s short throw and ultra short throw projectors make it easy to enjoy 100”+ screen sizes in rooms of any size simply by determining the ideal screen size and projection distance.
First, look for information about screen size and distance, which is typically expressed as “screen size @ distance” from screen within the specifications of our projector models. For example, the specification “100-inch @ 2.43M” means that the minimum distance you will need is 2.43 Meters. from the projector to the wall to get a 100″ screen. Because a 100-inch image with a 16:9 aspect ratio has a width of approximately 2.13M, this means that a space of about 1.95 sq.M to 3 sq. M, about the size of a small bedroom, is needed to project a 100-inch picture in this example.

To select the ideal projector for your home, you will need to measure the length and width of the room, and use the maximum distance the projector can be placed from the screen to filter for the specific projector model that will meet your ideal screen size from that distance. If the space has an irregular shape, such as an L shape or a polygon, first confirm furniture placement, then measure the distance between the two walls as the reference for purchasing a projector. Keep in mind the best setup position is where two walls are furthest apart in the space.
