YouTube Thumbnail Size
1280 by 720 pixels, 16:9, under 2 MB. Here are the specs, the safe area and the mistakes that make a thumbnail look blurry or cropped.
Wrong Dimensions vs. the Right Ones
A low-resolution image or the wrong ratio gets cropped or looks soft. 1280 by 720 at 16:9 is the standard.

The standard YouTube thumbnail size is 1280 by 720 pixels, in a 16:9 shape, as a JPG, GIF or PNG file under 2 MB. YouTube also asks for a width of at least 640 pixels. That's all you need for most uploads, and the rest of this page covers the details that trip people up.
The specs at a glance
| Property | What YouTube asks for | Notes |
|---|---|---|
| Resolution | 1280 by 720 pixels | Larger 16:9 images work, as long as the file stays under the size limit |
| Minimum width | 640 pixels | Smaller images look soft on larger screens |
| Aspect ratio | 16:9 | The same shape as the video player |
| File size | Under 2 MB | Checked when you upload |
| File type | JPG, GIF or PNG | WebP isn't on the list |
These are YouTube's published guidelines at the time of writing. If an upload is rejected, check YouTube Help for the current rules, because platforms change them.
Why 16:9
The shape matches the video player, so a thumbnail in 16:9 fills its space without bars or cropping. A square or vertical image gets cropped or letterboxed, and the part that gets lost is often the part you cared about. If you start with a photo in another shape, crop it to 16:9 first and decide yourself what stays in.
Where your thumbnail is shown
You upload one file, and YouTube shows it in many places at many sizes.
| Where | What it means for the image |
|---|---|
| Search results | Seen next to a title and a description. Text on the image can compete with them |
| Home feed | Seen in a grid with many other thumbnails, so contrast matters |
| Suggested videos | Often small, beside a watch page |
| Channel page and playlists | Seen together as a set, so a consistent look helps |
| Phone, tablet and TV | The same image at very different sizes |
You can't design for each one, so design for the smallest. If the thumbnail still makes sense at the size of a stamp, it holds up elsewhere.
Keep key content inside the safe area
YouTube puts a duration label on the bottom right corner of most thumbnails, and on some surfaces small icons appear on the top right. Anything in those corners can be covered. Keep text and faces toward the center and left, and leave a margin of a few percent around the edge.
JPG, PNG or GIF
- JPG gives small files and works well for photos and busy images. Most thumbnails should be JPGs.
- PNG keeps flat colors and crisp text edges well, but the files get large, and a full-size PNG can pass 2 MB. If that happens, export a JPG instead.
- GIF is allowed, but it supports only a limited range of colors, and it's rarely the best choice for a thumbnail.
If your file is over 2 MB, don't shrink the dimensions first. Lower the export quality a little. Most images stay sharp well before the file gets small enough.
How to resize an image without stretching it
Stretching a photo to fit makes faces look wrong, so resize in two steps.
- Crop first. Use your editor's crop tool with the 16:9 ratio and move the frame until the subject sits where you want it.
- Then set the size. Resize the cropped image to 1280 by 720, keeping the ratio locked.
- If the photo is too narrow to crop without losing the subject, extend the canvas instead. Fill the extra space with a color or a blurred copy of the same image.
- Export as a JPG at a high quality setting and check the file size.
How to check the size of a file
On Windows, right-click the file, choose Properties and open the Details tab, which lists the dimensions and the size. On a Mac, select the file and press Command and I to open Get Info, where the dimensions are under More Info. Most image editors also show them in the canvas or export settings.
Mistakes that lead to blurry or cropped thumbnails
- Starting from a small image and enlarging it. Upscaling adds pixels but not detail, so the result looks soft.
- Uploading a screenshot of a design. The screenshot may include borders or interface elements and may have the wrong shape.
- Using the wrong aspect ratio, such as 4:3 or square, and letting YouTube crop it.
- Saving the same file again and again as a JPG. Each save loses a little quality, so keep an original and export from it.
- Putting small text near the edges, where it's cropped on some surfaces or covered by the duration label.
Why a thumbnail can look blurry after upload
YouTube compresses images, so a thumbnail with fine detail, tiny text or heavy noise can look rougher after upload than it did on your screen. The fix is design, not size. Use larger, simpler shapes, bolder text and fewer small details. The YouTube thumbnail text page explains how big text should be.
Check it before you upload
- Look at the dimensions: 1280 by 720, or a larger 16:9.
- Look at the file size: under 2 MB.
- Shrink the image to stamp size, and check that you can still tell what it shows.
- Cover the bottom right corner with your thumb. Does anything important disappear?
- View it on your phone, since that's where many viewers will see it.
