Broadcast Resolution Lookup
Pick a broadcast format and get its exact active raster, aspect ratio and common frame rates — SD through 8K UHD.
The reference table editors reach for: UHD broadcast is 3840×2160 (16:9) while 4K DCI cinema is 4096×2160 (17:9) — a frequent and costly mix-up. SD rasters carry non-square pixels, so their stored 720-wide raster displays as 4:3 or 16:9 depending on PAR.
