Measure the circumference of your Head. If the measurement is 22" to 22 3/4" order a size Small. If the measurement is size 23" to 23 3/4" order a size Medium. As Shown Below. You should have a comfortably fitting Bandana that “stays put”.

Measure the circumference of your Head. You can use a tape measure (or a length of string that you will have to hold up to a tape measure) to determine the length. Place the string or tape around your head and behind your ears, across your forehead at the edge of your eyebrows, completely circling your head. Hold the tape firmly, but not too tightly. Basically you need to measure your head exactly where the do-rag or bandana will sit. If your measurement falls between sizes, choose the smaller size. (Example: your head measures 22 7/8, you would order a small.) You should have a comfortably fitting Bandana or Do-Rag that “stays put”.
