720p thumbs vs 1080p masters

YouTube thumbnail spec

YouTube’s help pages have long listed 1280×720 as the thumbnail upload size (16:9, under 2MB, JPG/PNG/GIF). A 1920×1080 still works but is heavier than you need for a thumb. If the still will also be a video frame, export 1920×1080 separately.

When 720p is enough

Email newsletters, older projectors, and many blog heroes never display more than ~1280 CSS pixels. Shipping 1920×1080 then letting the browser downscale wastes kilobytes. Use 1280×720 when the layout max-width is 1280 or less.

Readable type at 720p

Thumbnails are seen at postage-stamp size in search. Huge body text at 1280×720 still vanishes. Three to five words, thick stroke, high contrast. This tool does not set type — resize the designed graphic.

Not a Story size

1280×720 is landscape. Stories need 1080×1920. Mixing them causes black bars in the Instagram camera.

How it works

  1. 1

    Upload the designed thumb

    Start from a 16:9 composition. Faces belong in the right or left third so YouTube duration badges do not cover them.

  2. 2

    Lock 1280×720

    Pre-filled. Export JPG unless you need PNG transparency (YouTube thumbs rarely need it).

  3. 3

    Check file size

    Stay under YouTube’s 2MB thumb cap. Compress once if needed.
