Ring Sizing Guide

Before you start: It’s good to keep in mind following information.

Lets find your ring size:

if in doubt: most common ring sizes for women are (Size N or M) and for men (Size T)

Method 1: Buy a Ring Sizing Tool

This is the second best alternative to going to get your finger professionally measures at a store. Ring sizing tools can be very inexpensive and found easily online. I have listed some below to make it easier for you, but any will work:

Uk: here Brazil: here USA: here

Method 2: Using a Existing Ring

  1. Select a ring you already own that fits the desired finger. If you can, choose a ring that is a similar width to the one you wish to purchase.
  2. Use a ruler or tape measure and place the ring on top, measure the inside diameter from side to side of the ring in millimetres.
  3. Compare these measurements with our sizing guide.

note: All sizing and conversion charts vary slightly from brand to brand. The chart below is personalised for Mari Martins Rings but are still approximations.

Method 3: Use a Ring Sizer App

You can usually find a ring sizer app in the App Store or Google Play Store. I recommend the Ring Sizer by Jason Withers App for iPhones.

Note: Any ring sizing app will follow their own sizing standards that do not correspond directly to Mari Martins' sizes so be aware that this will not be accurate but can still be used for an approximation.

Method 4: Using a String or Piece of Paper

  1. Wrap a piece of string or paper around the base of the finger you want to measure.
  2. Mark the point where the string/paper overlaps and measure the length using a ruler.
  3. Compare these measurements with our sizing guide.

Here is a video explaining this method.

Please note: These methods may not give you the most accurate results, so use your discretion and try more than one method to cross verify. I recommend always sizing up if you are in doubt.
