I recommend measuring very snugly past the hairline where the elastic will sit to get the best fit. Select the wearer's actual head size and size down if between sizes.

How to measure size

Note: Elastic IS stretchy. You may prefer the band to be extra snug, and you may size down according to your preference.

However, for glitter headbands and swim bands, it is important to select the accurate head size so it won't be too small.

If you have bought headbands from other sites that use "finished size" choices, you can use the chart below to compare.
