Sizes listed are for neck circumference of your pet. Since bandana comes with snaps, I automatically add a few inches to the width when cutting fabric to ensure bandana won't be too tight. Width across top of bandana usually ends up being two inches more than pet's neck size. If your pet is fluffy, add a couple extra inches when picking the correct size. It's better to size up, than size down because you can always roll the bandana and snap it if it's too big. If you'd like an extra set of snaps for more flexibility in sizing, please see our listing for an extra snap for $1.00 Length of bandanas vary with size.
Each bandana is custom made to order so may vary in size slightly.
