Ring sizing guide

Simple steps how to measure your ring size at home

*Best and most accurate way of knowing your ring size is going to a professional jeweler or any jewelry store and get your fingers measured (usually it is free of charge)

Measuring ring inside diameter

Find a ring that fits you perfectly. Could be any ring you find at home.

Using a ruler or measuring tape measure the inside diameter of a ring in millimeters.

Using a table down below find a ring size that is true to your measurements.

"Ring sizer" app

Download "ring sizer" app on your phone (it's free).

Open the app and according to the instructions in the app measure your ring.

Compare your ring size to a table we provide down below.

Paper strip method

Cut a thin strip of paper.
Wrap the paper around your ring finger just below the knuckle.
Once it’s snug you’ll want to mark where the two ends meet on the inside of your finger with a pen. Just make sure you’re not wrapping it TOO snug. You’ll want to find a comfort fit vs. a tighter fit.
Flatten out the thin strip of paper and measure how many millimeters from the mark you just made to the end of the paper you used.
Match that measurement with the corresponding standard ring sizes, below.
