How to measure finger size

Sizing Guide Options

Measuring someone’s finger or ring size can be tricky, especially if you want to purchase an engagement ring as a surprise or choose a gift for someone. At LARRYAN Privé, our custom-made rings come with a complimentary resize which can be used within 4 weeks of collection. (It is important to note that some designs are excluded. Even with this in mind, it is worth taking a look at our ring size chart and doing a little bit of research to see if you can find out the ring size first, or at least, make a close guess.

The most accurate thing you can do is to come into our showroom and allow one of our jewellers to measure your finger, however, we know this is not an option for everyone so here are our helpful tips for sizing someone else’s finger, or your own!

Option I

The best and most accurate way to size your finger, would be to let a professional jeweller size you up, in their studio or retail store.

Our showroom is in Dymocks Building Level5 , 12B/428 George Street,

Option Ii

Perhaps you have access to a ring that is the correct size, whether it is an existing ring that you already own or one that belongs to a friend or family member. Roll up a small piece of paper, slide the roll through the ring and mark the overlap with a pen. This will then be used to measure the inner circumference of the ring to help us get the exact finger size. With a ruler, measure the length of the paper and use the ring size chart below to determine the ring size. Please also send us a photo of the ring you measured as the style and width of the band can play a part in how we determine the correct size. Ideally, the ring you measure should be a perfect fit on the same finger you want the new ring to fit on. If the ring you find is not worn on the actual finger, or it is a bit tight or loose, please mention this to help us estimate the best ring size.

Download our Printable LARRYAN Privé Ring Size Guide PDF. This guide includes a scale measuring device that will help you to establish the correct ring size. This is a great option for measuring the right ring size when your partner is part of the planning. We also have a ring size chart below that converts international sizes, in case you or your partner know their ring size in a different country.

Simply print the document.
Measure the 5cm guideline to ensure that the page has printed correctly.
In the print dialogue box, print scaling must be set to ‘None’ or ‘Do not scale’.
Cut out the ring sizer and carefully cut the slot on the wide end.
Place the end of the ring size measuring tape through the slot to make a loop.
Measure your ring size at the widest part of the finger, and ensure you can slide the ring on and off.
For some, this can be the knuckle or the base of the finger.
In order to establish the proper ring measurement, you need to ensure the paper tape measure has been pulled taut and is not sitting loosely.

Option Iv

Use the universal ring size chart below to convert ring sizes from different countries. Women’s rings and men’s rings are measured on the same scale. This ring size chart converts the inside diameter measurement as well as the inside circumference measurements. This is a handy guide that includes all standard ring sizes and half size measurements too.
