Charm Size & Compatibility Guide
CYCOLINKS · CHARM SIZING & COMPATIBILITY
Check the opening. Find the fit.
Charm dimensions and bracelet compatibility vary by design. Match the exact charm to the bracelet or necklace you plan to wear it on.
1. Check what it needs to pass over
Charms use millimetres for small details: 10mm = 1cm. A charm’s outside height and width do not tell you its opening size.
2. Compare the exact product
| Check | Why it matters |
|---|---|
| Opening / hole diameter | Must suit the chain and the parts it needs to pass over. |
| Charm height & width | Shows the size of the design and how much space it may need. |
| Clasp & end fittings | Can be wider than the chain itself. |
| Material & finish | Check sterling silver, enamel, plating or stone details on the listing. |

Approximate measurements for this charm only—not a standard for the whole range.
Can I add a charm to my existing bracelet?
Yes, where the exact charm and bracelet are compatible. This can let you mix bicycle and motorbike charms with an existing European-style or Pandora-style collection without buying a new bracelet.
Some charms can also be worn on a compatible thin necklace. Check the chain and end fittings against the opening first. Bracelet and necklace styling items are sold separately unless the listing states otherwise.
