YouTube thumbnails are 1280×720 — a 16:9 frame at 720p. That is the size to upload, and it is also the size YouTube uses when generating the smaller versions it shows in search results, sidebars and mobile feeds.
There is a second constraint people hit constantly: YouTube rejects thumbnail files over 2MB. A detailed 1280×720 PNG exported from a design tool can easily exceed that, which is where the compression here earns its place. Switch the output to JPEG and this will bring almost any thumbnail well under the limit while keeping it sharp.
The design consideration that matters more than either: your thumbnail will usually be seen at a fraction of its actual size. On a phone feed it may be barely 300 pixels wide. Fine detail and small text disappear entirely at that scale, which is why effective thumbnails use few, large elements and high contrast. Resizing your image here does not fix a design that only works at full size — check it small before you commit.
Keep it at 1280×720 rather than uploading something larger. YouTube gains nothing from extra resolution and will simply downscale it.

Frequently asked questions
What is the correct YouTube thumbnail size?
1280×720 pixels, a 16:9 ratio. YouTube generates all the smaller variants it needs from that.
What is the YouTube thumbnail file size limit?
2MB. Detailed PNG exports frequently exceed it. Converting to JPEG here will bring almost any thumbnail comfortably under.
Should the thumbnail be PNG or JPEG?
JPEG is the safer choice — much smaller, and well under the 2MB limit. Use PNG only if your thumbnail is mostly flat graphics and text, where PNG can look cleaner.
Why does my thumbnail look cluttered in search results?
Because it is displayed far smaller than you designed it, sometimes around 300 pixels wide. Fine detail and small text vanish at that size. Check your design at thumbnail scale before uploading.
