Most of our bracelets are custom made to order. For those that require sizing, please measure your wrist and add the dimensions mentioned in the product description.  If possible, take a soft measuring tape like the one in the photo to measure. Please try and measure correctly so the bracelets will fit you perfectly! If you need assistance with this please contact us. (In this photo, the wrist size would be 6", so I would add either 1/2" or 3/4" to a bracelet depending on the notes in the description)
