That is roughly <strong>7.26 ft \u00d7 4.09 ft<\/strong> or <strong>221.4 cm \u00d7 124.5 cm<\/strong>. The \u201c100 inches\u201d refers to the diagonal, not the width.<\/p>\n<p>Actual product dimensions will be larger once you include a fixed-frame border, retractable housing, mounting brackets or tensioning hardware. Brandligo has not independently measured every screen model, so use the manufacturer\u2019s overall dimensions before ordering or mounting hardware.<\/p>\n<div id=\"ez-toc-container\"

The correct lens-to-screen distance depends on the projector\u2019s throw ratio:<\/p>\n<p><strong>Throw distance = throw ratio \u00d7 image width<\/strong><\/p>\n<p>For a 100-inch 16:9 image, the image width is about 87.2 inches. A projector with a 1.5:1 throw ratio therefore needs roughly 131 inches, or 10.9 feet, from lens to screen. A short-throw or ultra-short-throw projector can create the same diagonal from much closer. Always use the manufacturer\u2019s model-specific throw range before installing a mount.<\/p>\n<p>See Brandligo\u2019s <a href=\"https:\/\/www.brandligo.com\/blog\/how-far-projector-should-be-from-screen-the-ultimate-guide\/\">Projector Throw Distance Guide<\/a> for the full calculation.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Is_100_inches_good_for_a_meeting_room\"><\/span>Is 100 inches good for a meeting room?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>It can be, but a business screen should be sized around the farthest seat and the content being shown. A 100-inch image may work well for presentations in a small or medium room, but spreadsheets, dashboards and dense text require readability checks from the back row. Ambient light also matters because increasing screen area spreads the projector\u2019s light over a larger surface.<\/p>\n<p>Many business and education projectors use 16:10 rather than 16:9. A 100-inch 16:10 image is about <strong>84.8 inches wide by 53.0 inches high<\/strong>, giving more vertical space for laptop and presentation content.

You need enough projector brightness for the screen area and room conditions, and the screen surface must match the projector type and seating layout. Ambient-light-rejecting screens can help in some rooms but can introduce viewing-angle and compatibility trade-offs.<\/p>\n<p>Do not assume a standard ALR screen is suitable for an ultra-short-throw projector.
