How to fix YouTube thumbnail text that gets cut off

You spent twenty minutes on the headline. You exported it, uploaded it, opened the video page, and the last word is half gone. Or the first letter is clipped. Or the whole bottom line is hiding behind something.

Thumbnail text gets cut off for a small number of reasons, and each one has a clear fix. Find yours below.

1. It’s under a YouTube overlay

This is the most common cause, and the text isn’t technically “cut off” at all. It’s covered.

YouTube draws its own UI on top of your image: the duration badge in the bottom-right, a red progress bar along the bottom edge for viewers who’ve already started the video, hover icons near the top-right on desktop, and a “LIVE” or “PREMIERE” label for streams. Anything you put in those spots will be hidden for at least some viewers.

The fix: keep text out of the bottom strip and away from the bottom-right corner entirely. A good working margin is about 8% in from every edge, plus a keep-out box in the bottom-right roughly 18% of the width and 15% of the height. We wrote a whole post on the overlay zones if you want the details.

2. Your image isn’t 16:9

YouTube thumbnails are 16:9. If you upload something else (a 4:3 export, a square graphic you reused from Instagram, a 1080×1350 portrait), YouTube has to make it fit. Depending on where it’s shown, that means black bars or a crop, and a crop always loses the edges first. Edges are where text tends to live.

The fix: set your canvas to 1280×720 (or 2560×1440 if you like working bigger) before you design, not after. Resizing a finished design to a different aspect ratio means either squashing it or cropping it, and both are worse than starting at the right size. Check the exported file’s dimensions before you upload; a “1280×720” template with an accidental extra pixel of bleed is still the wrong shape.

3. The text runs edge to edge

Even at the correct size, a headline that spans the full width has nowhere to go. Some surfaces round the thumbnail’s corners. Some trim a sliver off the sides to fit a grid. Some show the image a little larger on mobile, closer to the screen edge. None of these take much, but if your first letter is two pixels from the border, a little is all it takes.

The fix: shorten the text instead of shrinking it. If a headline only fits by touching both edges, it’s too long for a thumbnail. Three or four words, large, sitting comfortably inside the margin, beats seven words that fill the frame.

4. It’s a Short, or it’s being shown as a vertical crop

Shorts are vertical, and Shorts feeds show a tall slot. A wide frame or a 16:9 graphic dropped into that slot loses its left and right sides. Text that spans the width gets cut on both ends.

The fix: for Shorts, design text for a narrow centre column, roughly the middle third of a 16:9 frame or the middle of a 9:16 one. If the same image has to work for a long-form video and a Short, stack the words vertically in the centre rather than spreading them across.

5. It isn’t cut off, it’s just too small

Sometimes the text is all there and simply unreadable. On a phone, a thumbnail is often about the width of a thumb. In the desktop sidebar it’s smaller. Thin fonts, outlines that blur into the background, and a second line of smaller text all turn into a smudge, and a smudge reads as “cut off” when you’re scrolling.

The fix: shrink your thumbnail to about 320 pixels wide and look at it from arm’s length. If you can’t read it instantly, use fewer words, a heavier font, and more contrast between the text and whatever’s behind it.

Wait, is it the title?

Worth checking: if the words vanishing are below the image, under the thumbnail rather than on it, that’s your video title being truncated, which is a different problem. Each surface shortens titles to a different length, so front-load the words that matter and treat everything after the first few as a bonus.

A two-minute check before you upload

1. Confirm the export is exactly 16:9 and under 2 MB.
2. Preview it with the desktop and mobile overlays drawn on top.
3. Make sure nothing important is in the bottom strip, the bottom-right corner, or within about 8% of any edge.
4. If it’s for a Short, check that the text survives a centre crop.
5. Shrink it and do the squint test.

Step two is the one people skip, because seeing the overlays normally means uploading the thumbnail first. The YouTube Thumbnail Checker draws them on your image right in the browser, so you can catch the clipped word before anyone else sees it, and the file never leaves your computer.
