+You can configure a merge queue's merge group size, which determines how many pull requests are included in each merge group. When there are no status check failures or merge conflicts, choosing the default "small" merge group size will form groups containing 2 pull requests. If you want to group more pull requests per group, you may choose the "medium" merge group size to form groups containing 5 pull requests each.

 For information about how to enable the merge queue protection setting, see "[Managing a branch protection rule](/repositories/configuring-branches-and-merges-in-your-repository/defining-the-mergeability-of-pull-requests/managing-a-branch-protection-rule#creating-a-branch-protection-rule)."
