YouTube Thumbnail Maker

Why thumbnail size matters

A YouTube thumbnail is 1280×720 pixels with a 16:9 aspect ratio. Upload anything off-size and YouTube crops or letterboxes it, so your carefully-placed text can end up cut off. This maker locks the canvas to the exact size, so what you design is exactly what viewers see.

The thumbnail is the single biggest factor in whether someone clicks. A short, high-contrast headline — three or four punchy words — over a clean gradient or a darkened photo reads instantly, even at the tiny size thumbnails appear in feeds and search.

How to make a YouTube thumbnail

1. It opens at 1280×720. The YouTube thumbnail size is already selected, so the canvas is the right shape.
2. Add your text. Type a short, bold headline and an optional supporting line. Pick the colour, size, and position.
3. Choose a background. Use a gradient, a solid colour, or upload your own photo and darken it so the text pops.
4. Download. Export as PNG (or JPG for a photo background) at full 1280×720 and upload it to YouTube.

Make text readable at small sizes

Thumbnails are viewed small, so use few words, a heavy weight, and turn on the shadow for contrast. Keep important text away from the bottom-right corner, where the video duration badge sits.
