Scrunchies come in two sizes: regular and large. Both should wrap your hair 2-3 times depending on your hair's thickness.
The regular size scrunchies are about 3.5/4" in outer diameter, while the large scrunchies are about 6/6.5" in outer diameter. These are appromiate sizes since they are handmade and vary depending on style.
The elastic length of both sizes is relatively the same but larger scrunchies will weigh more, so consider regular sized scrunchies if you have thin hair.
If you have very thin or short hair, send me a message since I make small scrunchies to order.
