THE PERFECT FIT

If you don't know your bracelet size, grab a tape measure, piece of string, or thin strip of paper. Wrap it around your desired wrist and mark the place where it joins. Lay it on a ruler to measure the length up to the mark in inches. Ensure there's space between the string and your skin for a finger or two. Use the chart above to match the measurement to the closest Kinn bracelet size.

We recommend sizing up for thicker bracelets, like the Bold Cobra Chain Bracelet, Mia Link Chain Bracelet, or Rome Bold Link Chain Bracelet.

If you have questions about bracelet sizing, please contact us at hey@kinnstudio.com.

THE PERFECT FIT

Finding the perfect necklace length(s) comes down to personal preference. If you're not sure what length you want, measure and cut a piece of string to the same length as the necklace and place it around your neck to see where it falls. Repeat the process to see how necklaces of difference lengths might look together.
