How To Measure Bracelet Length

What you will need

  • Pen or pencil
  • Tape measure or
  • Length of string and a ruler

What to do

  1. Wrap the tape measure or string around the wrist on which you plan to wear your bracelet.
  2. Make a note of the number at the point where the tape meets the 0.
  3. To ensure the bracelet fits comfortably, add 1.5 cm.
  4. You can then add or subtract centimeters according to whether you prefer a loose, exact or tight fit.

How To Measure Ring Size

What you will need

  • Pen or pencil
  • Tape measure or
  • Length of string and a ruler

What to do

  1. Wrap the tape measure or string snugly around your finger at the base of the knuckle
  2. Mark where the ends of the string overlap.
  3. Lay it flat and use a ruler to measure the length in mm.
  4. This will give you the internal circumference in mm.
  5. Use the chart below to find the corresponding ring size.

The thicker the ring, the tighter the fit, so if you choose a ring with a deep band width, you will likely need to go one size up. The best time of day to measure is in the evening, when your fingers are largest. Avoid measuring when you’re cold, as fingers are at least half a size smaller.
