Clasp Size Calculator — Right Clasp for Your Jewellery
Determine the right clasp type and size based on chain weight and jewellery style.
Width of chain or bead strand
How We Calculate This
The calculator recommends clasp types and sizes based on two factors: the weight of your chain or beads, and the type of jewellery.
Bracelets need clasps that are easy to fasten one-handed. Necklaces can use smaller clasps that sit at the back of the neck. Heavier pieces need larger, stronger clasps.
