The right YouTube thumbnail size, and how to get it
Custom thumbnails should be 1280×720 pixels in a 16:9 shape, at least 640 pixels wide, saved as JPG, PNG or a still GIF, and under 2 MB. If your design doesn't match, the upload can fail or the image gets squashed, cropped or blurry. This free YouTube thumbnail resizer fixes all of that in your browser in seconds.
Which fit option to use
- Fill & crop: best for photos that are almost 16:9. Pick which part to keep (top, bottom, centre).
- Fit with colour: keeps the whole image and adds bars in a colour you choose. Good for logos and graphics.
- Fit with blur: places the whole image over a blurred copy of itself. Ideal for vertical phone photos and screenshots.
Staying under 2 MB
Choose JPG and the tool automatically lowers the quality just enough to fit under the limit. PNG keeps text perfectly sharp but can be larger, so switch to JPG if it goes over. Then check how it looks among other videos with the thumbnail preview tool.
