|---|---|---|---|
| Collar | 12-13 | 30-33 | Tight around the neck |
| Choker | 14-16 | 36-41 | At the base of the neck |

How to choose the right chain length: The best chain length depends on your neck size, body type, and neckline of your clothing. A general guideline is to measure your neck circumference and add 2-4 inches (5-10 cm) for a comfortable choker length. For each step up in style category, add approximately 3-6 inches (8-15 cm).
Conversion formula:
- Inches to centimeters: cm = inches x 2.54
- Centimeters to inches: inches = cm / 2.54
Bracelet lengths for reference:
| Size | Inches | Centimeters |
|---|---|---|
| Small wrist | 6.5-7 | 16.5-17.8 |
| Medium wrist | 7-7.5 | 17.8-19 |
| Large wrist | 7.5-8 | 19-20.3 |
| Anklet | 9-11 | 23-28 |
Practical tips:
- When ordering online, use a piece of string to simulate the necklace length before purchasing.
- Pendant necklaces typically look best at princess or matinee length so the pendant has room to hang.
- Layering multiple necklaces works best when each piece is at least 2-3 inches (5-8 cm) different in length.
- Men’s chains are typically 18-24 inches (46-61 cm), with 20 inches (51 cm) being the most common.
