Frequently asked questions
What size should YouTube thumbnails be?+
YouTube's official specification is 1280×720 pixels at 16:9 aspect ratio, maximum 2MB, in JPG, GIF, BMP, or PNG format. The minimum recommended size is 640×360, but 1280×720 displays sharply across all placements including high-DPI mobile screens.
What is the YouTube safe zone for thumbnails?+
YouTube can clip the outer 5% of thumbnails on some devices and placements (TVs, smaller mobile screens). Keep all important text and faces within the central 90% of the frame. The JAD safe zone overlay marks this boundary so you can reposition text before exporting.
Does thumbnail quality affect YouTube ranking?+
Not directly — YouTube does not score thumbnail image quality. But click-through rate (CTR) heavily influences video reach, and sharp, high-contrast thumbnails with readable text consistently outperform blurry ones. Exporting at maximum JPEG quality ensures YouTube's own re-encoding does not introduce visible artefacts.
