YouTube's thumbnail requirements
YouTube recommends a thumbnail of 1280 × 720 pixels with a 16:9 aspect ratio. The file should stay under 2 MB and can be JPG, PNG or WebP. Hitting these numbers ensures your thumbnail looks crisp everywhere, from a phone feed to a TV screen.
- Resolution: 1280 × 720 (16:9)
- Minimum width: 640 pixels
- Max file size: 2 MB
- Formats: JPG, PNG, WebP
Why 1280×720 specifically
720p is the sweet spot: large enough to stay sharp when YouTube scales it up for big displays, but small enough to keep the file under the size limit. Designing at this exact resolution means the text and focal point you place will land precisely where you expect across every device.
Design tips that survive shrinking
Thumbnails are often viewed tiny. Keep text short and bold, use high contrast, and make sure your subject reads clearly at a fraction of full size. Place key elements away from the bottom-right corner, where the video duration badge sits.
Resize and export privately
Start from your artwork at full resolution, then use a 1280×720 preset to lock the size. Crop to 16:9 first if the source is a different shape so nothing important gets cut. Export as high-quality JPG or WebP to stay under 2 MB while keeping text crisp. A browser-based resizer does all of this locally — handy when the thumbnail is for a video that isn't public yet.
Get more clicks
A correctly sized, sharp thumbnail is one of the cheapest ways to improve click-through. Use the 1280×720 preset, design for small sizes, and export without uploading your unreleased artwork anywhere.
