Measure a necklace you already like
Open the clasp and lay the necklace straight without pulling or stretching it. Measure from end to end, including the fastening. If there is an extender, record the base length and the extra adjustment separately, and note the position you usually fasten.
For a gift, use a necklace the recipient actually wears at the intended position. A long pendant necklace is not a reliable reference for a close-fitting choker.
