Complete Jewelry Sizing Guide for Wristwear (cm / inch)

This guide combines step-by-step measurement instructions, size conversion charts, and fit tips to help you find the perfect bracelet, bangle, or cuff. All measurements include both centimeters (cm) and inches (in) for convenience.

1. How to Measure Your Wrist Circumference

Follow these steps for accurate results—no special tools required!

Method 1: Soft Tape Measure

  1. Wrap the soft tape measure around the slimmest part of your wrist (just above the wrist bone).
  2. Keep the tape snug but not tight—avoid squeezing your skin or leaving extra space.
  3. Read the measurement directly (1 inch ≈ 2.54 cm) and note both cm and in values.

Method 2: String + Ruler (No Tape Measure Needed)

  1. Take a string, thread, or ribbon and wrap it around your wrist’s slimmest part.
  2. Mark the overlapping point with a pen/scissors (keep it snug, not tight).
  3. Lay the string flat against a ruler and measure the length between marks—this is your wrist circumference.

3. Fit Tips by Jewelry Type

Adjustable Bracelets (Beaded, Cord, Stretch Styles)

  • The size range in the chart covers stretchable or sliding designs—no need to add extra length.
  • Ideal for casual wear; fits most wrist shapes with minimal adjustment.

Fixed-Size Bracelets (Metal Chain, Link Styles)

  • Add 1.0–1.5 cm (0.39–0.59 in) to your wrist circumference for a comfortable, not-too-tight fit.
  • If you prefer a looser fit (e.g., layered with other bracelets), add 1.5–2.0 cm (0.59–0.79 in).

Bangles (Solid Circular Styles)

  • For a snug fit (stays close to the wrist), choose the smaller diameter in the range.
  • For a looser fit (slides easily up and down), opt for the larger diameter.
  • If you have larger knuckles, measure the knuckle circumference and choose a bangle diameter 0.2–0.3 cm (0.08–0.12 in) larger than that.

4. Material-Specific Adjustment Tips

  • Elastic Cord Bracelets: Stick to your exact wrist circumference—elastic stretches for a snug yet flexible fit.
  • Beaded Bracelets (Non-Stretch): Add 0.5–1.0 cm (0.20–0.39 in) to avoid tightness around the wrist.
  • Thick Metal Cuffs: Add 0.3–0.5 cm (0.12–0.20 in) to account for the cuff’s thickness.

Pro Tips for Accuracy

  • Measure at room temperature—wrists can swell slightly in the morning, after exercise, or in hot weather.
  • Take 2–3 measurements and use the average for the most precise result.
  • If gifting and you don’t know the exact wrist size, choose an adjustable style or the medium (M/L) size for versatility.
