Working Out Correct Finger/Ring Sizes

Working Out Correct Finger/Ring Sizes

Method 1: Simple Measurement By Appointment

We have a professional measuring kit here at our showroom and can measure your finger accurately right away if you pop in for a visit. This process takes about 5 minutes and you can be 100% sure that it’s accurate and correct! Easily the best and most highly recommended method.

 

Method 2: The String/Paper

Begin by wrapping a piece of string or a strip of paper around the base of the required finger. Use a marker to indicate the size and cut the string or paper where it overlaps on the finger. Using a ruler or measuring tape, have a look at the measurement in mm of the string and find the corresponding measurement on our chart below for a finger size.

Method 3: The Existing Ring (1)

If you already have a ring that fits the finger you want to measure, simply use the chart above and find the one that is the closest match for it using the inner diameter of the ring (not the outer diameter). This method is not always as accurate as the method above but it can save time.

Method 4: The Existing Ring (2)

For this method you will also require an existing ring that fits the finger you want to measure. Using a flat ruler, simply measure the inner diameter in mm and refer once again to the size chart. If you are attempting to do this as a surprise for your partner (an do not want them to know you are measuring their rings) you can also use a bar of soap as a mold by pressing the ring you’d like to measure as deep into the bar as possible and then measuring the inner diameter when you are able to.

 

Note: Sometimes a ring will fall within a Half Size measurement (example Q 1/2). If you find that the finger size is sitting somewhere between two main sizes we always recommend choosing the larger one as this is much easier to correct than if the size is on the smaller side. We recommend repeating these techniques at least two or three times to ensure accuracy as far as possible.
