TV and Projector Placement

These pages turn a few measurements into placement numbers: the height of a TV’s center, bottom and top edges on the wall, viewing distance ranges for a screen size, a TV size for a seating distance, and projector screen size and throw distance. Where published guidance differs, each page shows the sources side by side instead of averaging them, because recommendations for height and distance are guidelines and not rules.

Tools in this group

• Projector Screen Size Calculator — Enter a diagonal, a width or your wall space and an aspect ratio to see the screen width, height, area and the viewing distances for the angles in the sources.
• Projector Throw Distance Calculator — Enter the image size and the throw ratio from the spec sheet to see how far the projector sits from the screen, or enter the distance to see the image size, with lens shift.
• TV Mounting Height Calculator — Enter the TV size, your eye height, the distance and a center-height rule to see where the center, bottom and top edges land and the angle up to the top edge.
• TV Size for a Room — Enter how far you sit from the TV, or the room length, to see the screen sizes that fit by viewing angle and by each guide, plus a table of listed sizes.
• TV Viewing Distance Calculator — Enter the TV size and aspect ratio to see the viewing distance each source gives and the distance for a viewing angle you choose, or start from your seating distance.
