File and repository size limitations
We recommend repositories be kept under 1GB each. Repositories have a hard limit of 100GB. If you reach 75GB you'll receive a warning from Git in your terminal when you push. This limit is easy to stay within if large files are kept out of the repository. If your repository exceeds 1GB, you might receive a polite email from GitHub Support requesting that you reduce the size of the repository to bring it back down.
In addition, we place a strict limit of files exceeding 100 MB in size. For more information, see "Working with large files."
