Picking a projector screen size is mostly a geometry question: how far you sit from the screen, how much wall you have, and how far your projector can throw the image. Get those three numbers right and the size picks itself. This guide walks through each one, using the 16:9 format that almost all home theatre and presentation projectors use today.<\/p>\n

1. Start with your seating distance<\/h2>\n

A comfortable picture fills roughly a 30\u201340\u00b0 viewing angle from your seat. For a 16:9 screen, that works out to a simple rule:<\/p>\n

Screen diagonal \u2248 your seating distance \u00f7 1.2 to 1.6<\/strong><\/p>\n

So if your couch is 12 feet from the wall, a screen between about 90\u2033 and 120\u2033 will feel immersive without making you turn your head. Sitting closer than the range means the image may look soft on lower-resolution content; sitting farther away means fine detail \u2014 subtitles, spreadsheets, hockey scores \u2014 gets hard to read.<\/p>\n

2. Projector screen size chart (16:9)<\/h2>\n

The advertised size of a screen is its diagonal. What actually has to fit on your wall is the image width and height:<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n
Screen size (diagonal)<\/th>\nImage width<\/th>\nImage height<\/th>\nSuggested seating distance<\/th>\n<\/tr>\n<\/thead>\n
80\u2033<\/td>\n69.7\u2033<\/td>\n39.2\u2033<\/td>\n8.0 \u2013 10.7 ft<\/td>\n<\/tr>\n
92\u2033<\/td>\n80.2\u2033<\/td>\n45.1\u2033<\/td>\n9.2 \u2013 12.3 ft<\/td>\n<\/tr>\n
100\u2033<\/td>\n87.2\u2033<\/td>\n49.0\u2033<\/td>\n10.0 \u2013 13.3 ft<\/td>\n<\/tr>\n
110\u2033<\/td>\n95.9\u2033<\/td>\n53.9\u2033<\/td>\n11.0 \u2013 14.7 ft<\/td>\n<\/tr>\n
120\u2033<\/td>\n104.6\u2033<\/td>\n58.8\u2033<\/td>\n12.0 \u2013 16.0 ft<\/td>\n<\/tr>\n
135\u2033<\/td>\n117.7\u2033<\/td>\n66.2\u2033<\/td>\n13.5 \u2013 18.0 ft<\/td>\n<\/tr>\n
150\u2033<\/td>\n130.7\u2033<\/td>\n73.5\u2033<\/td>\n15.0 \u2013 20.0 ft<\/td>\n<\/tr>\n
165\u2033<\/td>\n143.8\u2033<\/td>\n80.9\u2033<\/td>\n16.5 \u2013 22.0 ft<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

3. Check the wall, not just the image<\/h2>\n

The viewing area is not the whole screen. A fixed frame screen adds a border frame around the image on all four sides, and a motorized or manual screen sits inside a casing that is wider than the viewing area, with a weight bar below it. Measure your wall width and ceiling height against the product’s overall dimensions, and leave a little clearance on each side. If the wall is tight, stepping down one size is better than a screen that crowds the corners of the room.<\/p>\n

4. Make sure your projector can fill it<\/h2>\n

A bigger screen also needs a longer throw. How far back the projector must sit depends on its throw ratio, and projectors differ a lot. Take one of the most popular home models, the Epson Home Cinema 1080 (throw ratio 1.02\u20131.23): it fills a 120\u2033 screen from 8.9 \u2013 10.7 ft<\/strong>. A longer-throw model with a ratio of 1.32\u20132.15 needs 11.5 \u2013 18.7 ft<\/strong> for the same 120\u2033 image \u2014 more than some rooms have.<\/p>\n

Before you order, run your own projector model through our free Calculateur de distance de projection<\/a> \u2014 pick your model, enter a screen size, and it returns the exact distance range plus the screens we carry in that size.<\/p>\n
