Three easy ways to work out your ring size at home, plus a full conversion chart if you already know it in another system.
Wrap a thin strip of string or paper around the base of your finger. Mark where it overlaps, then measure the length in millimetres.
Enter that measurement — or the inner diameter of a ring that already fits — into the calculator below to get your size instantly.
Every WeddingRing.lk piece includes a free in-store fitting, and lifetime resizing if it ever needs adjusting.
Measure at the end of the day when fingers are largest, avoid measuring when cold, and measure your dominant hand for that hand's ring.
Not sure? Measure the inside circumference of a ring you already own and wear on that finger.
