How big should the bail be?

The bail opening height should be at least the pendant thickness plus 4 mm to allow the chain to slide freely. Width should be proportional to the pendant — roughly 20% of pendant width as a minimum.

What size pendant looks best on a chain?

As a guide, small pendants (10-15 mm) suit fine chains, medium pendants (15-25 mm) work with most chains, and large pendants (25 mm+) need medium to thick chains for visual balance.

Can I use a jump ring instead of a bail?

Yes, a jump ring works well for lightweight pendants. Use a jump ring that is large enough for the chain to pass through and strong enough to hold the pendant weight.

How We Calculate This

The calculator determines minimum bail dimensions based on your pendant size and chosen chain type:

Bail minimum width = 20% of pendant width (at least 3 mm)
Bail minimum height = pendant thickness + 4 mm clearance

The chain width recommendation ensures visual balance between the pendant and chain.
