Frame-Grab Print Size Calculator
How big can you print a still grabbed from video? Enter the raster and a target DPI to get the maximum clean print dimensions.
A 4K frame grab prints cleanly at 12.8×7.2 inches at 300 DPI — fine for a magazine page, not a poster. Drop to 150 DPI (acceptable at viewing distance) and you double the print size. This is why poster art is shot on stills cameras, not pulled from video.
