How to make a github readme banner
- Type a short title. The text resizes itself to fit the 1280 × 320 shape.
- Choose a background and text color. Pick Round photo on the right to keep the left side free.
- Turn on Show safe zone guide to check that nothing important sits too close to the edges.
- Keep the format on JPG, then click Download banner. A short video ad plays first, then your file downloads.
- Upload it in your repository and reference it at the top of README.md.
Design tips for a 1280×320 image
- This shape is very wide and short, so use a few large words instead of a sentence.
- Keep important text near the center, and leave a little margin at both ends so nothing touches the edge.
- Need a different size? Use the Banner size menu above to switch to another preset or type your own width and height.
