FIND YOUR PERFECT FIT

At Aclama, the perfect fit is part of the experience. Our Size Guide ensures every piece rests with effortless elegance. As if it were designed solely for you.

Using a Ring You Already Own

  1. Select a ring that fits the intended finger.

  2. Measure the inside diameter of the ring with a ruler (in millimeters).

  3. Match the measurement to the Aclama Ring Size Guide.

String or Paper Method

  1. Cut a thin strip of paper (or use a piece of string).
  2. Wrap it around the base of your finger where the ring will sit.
  3. Mark the spot where the paper/string overlaps.
  4. Measure the length in millimeters.This is your finger’s circumference.
  5. Use the Aclama Ring Size Guide to find your size.

*Measure at the end of the day when your fingers are at their largest.
*Avoid measuring when your hands are cold, as fingers may be smaller.
*If between two sizes, Aclama recommends choosing the larger size for comfort.

Measure Your Wrist
 
  1. Wrap a soft measuring tape or string around your wrist, just below the wrist bone.
  2. Note the measurement in millimeters (mm).
  3. Compare it to the Aclama Bracelet Size Guide below.
  4. For a loose fit, add 10–20 mm to your wrist measurement.

Your bracelet should sit comfortably around your wrist — not too tight, not too loose. For a relaxed fit, choose a size 10–20 mm larger than your wrist measurement.

Measure Your Neck
 
  1. Decide where you want the necklace to sit (neckline, collarbone, bust, or longer).
  2. Measure your neck or existing chain in centimeters (cm).
  3. Use the Aclama Necklace & Chain Length Guide to pick your size.

Choose your necklace size based on neckline and style. For pendants, ensure the chain allows the piece to sit comfortably and visibly.
