Part of our complete diamond tennis bracelet buying guide.
Tennis bracelet sizing is straightforward but has a few nuances. The 7mm rule is the most common guideline, but it depends on wrist size and diamond carat weight. A 6mm bracelet suits smaller wrists and a 7mm bracelet suits larger wrists. Carat weight does not affect size but affects how the bracelet looks and feels. If you fall between sizes, 7mm is generally the better choice for comfort and visual balance.
Quick Answer: How to Size a Tennis Bracelet
- Measure your wrist — use string or tape, measure in millimeters where you want the bracelet to sit
- 7mm rule — wrist 185–190 mm (7.3–7.5 inches) for 7mm, 180–185 mm (7.1–7.3 inches) for 6mm
- Carat weight does not affect size
- 6mm is more comfortable for smaller wrists; 7mm is more common and better for larger wrists
- Tennis bracelets are flexible and conform to wrist shape

How to Measure Your Wrist
Wrap around your wrist where you want the bracelet to sit, mark the overlap, measure in millimeters.
Add 0.5–1 inch to your wrist measurement for comfortable drape. Tennis bracelets should not sit tight against the skin.
