Depending on the pendant's style and personal choice, the optimum chain necklace size will vary. Typically, a pendant necklace has a chain that is between 40 to 60 cm or 16 to 24 inches long. For smaller pendants and chokers, a 40cm / 16-inch chain lays close to the neck and is ideal; a 45cm / 18-inch chain is a popular choice for daily use. A 50cm to 60 cm or 20 to 24-inch chain enables the pendant to hang lower and become the centre of attention for pendants with bigger or more intricate patterns. When choosing a chain length, keep in mind that it has a significant impact on how the pendant will sit and look when worn. You should also take your neck size, personal style preferences, and the pendant's size into consideration.
