Bracelet Sizing Tips
How to MeasureWrap a flexible measuring tape around your wrist just above the wrist bone. Note the measurement in inches.
Comfort FitAdd 0.5 to 1 inch to your wrist measurement for a comfortable, non-restrictive fit.
Bangle vs. ChainBangles need to slip over the hand — measure the widest part of your hand (knuckles closed) for bangle sizing.
LayeringWhen stacking multiple bracelets, go up 0.5 inch in size to allow room for movement between pieces.
How to Measure
Follow these simple steps to measure your ring, bracelet, or necklace size accurately at home.
Gather Your Tools
You will need a flexible measuring tape, a thin strip of paper or string, a ruler, and a pen.
Measure Carefully
Wrap the tape or string snugly (not tight) around the finger, wrist, or neck. Mark the overlap point.
Record the Length
Lay the string flat against a ruler and note the measurement in millimeters or inches.
Find Your Size
Compare your measurement against the sizing charts above. If between sizes, choose the larger one.
Confirm Comfort
Ensure the piece can slide on and off comfortably. Jewelry should feel secure without being restrictive.
Ring Stacking & Sizing
Stacking multiple rings? You may need to adjust your ring size. When wearing several rings together, consider going up half a size for comfort. Learn more in our ring stacking guide.
