Finding the correct ring size at home or in our jewellery showroom.
Ring size help video
In today’s video, I’ll provide the solution to a problem that many of you face when buying an engagement ring or a wedding ring.
The problem is getting the correct ring size for your ring to ensure a perfect fit.
Both men and women worry about buying the wrong size. It’s particularly important when you consider many ring designs can’t be resized—for example, full eternity bands where the diamonds are set around the ring. Ideally, we like to check finger sizes in person in our showroom, but not everyone can visit us.
As a result, for many of our online clients, we had to create a system to find the correct finger size—which can be done in the comfort of your home.
So, how does it work?
How we ensure the correct ring fit
We’ve created the “Perfect Size Service” which we’ve also added to the Serendipity Diamonds website.
First, we send out a Multisizer tool. It’s a plastic strap with UK ring sizes and resembles a cable tie.
Now, this multisizer, on its own, is a good tool to estimate finger size, but it can be tricky to get a precise reading because the strap moves around when you slide it on and off the finger.
The strap goes around the finger’s base to give you an idea of the finger size. Don’t slide it over the knuckle because the reading will change. Instead, attach it around the fleshy part of the finger where you normally wear a ring.
Approximating size as the first step
With the Multisizer, you can get an approximate size.
And next, we post out ring samples in the closest sizes. Each sample ring is a simple aluminium band precision engineered in half-finger sizes.
So, to clarify, if the Multisizer gives you a size S as your finger size, we’ll send out R1/2, S and S1/2 ring sizes to try.
This service has three widths – 2.5mm (perfect for engagement rings), 5mm and 7mm.
So you try these after you’ve used the Multisizer to be confident you’ve established the correct finger size.
But how do you ensure the ring fits correctly?
How should the fit of a ring feel?
Well, I advise choosing a size that goes onto the finger and sits without moving around or spinning on the finger. You want the ring to be snug, difficult to remove, and only removable by stretching the hand to take the ring off. Otherwise, you’ll risk losing your ring, for example, when your hands are cold or wet.
Once you know the correct size, return the sample rings to us in a pre-paid envelope.
We’ll refund the cost of the size service from your final order.
For international clients
For international clients in locations such as the USA, send the rings back by any tracked postal service and then email us a copy of your receipt for the postage, and we’ll refund the return delivery cost.
Finally, there are so many videos advising on ring size techniques.
Many involve tying pieces of string around the finger, or strips of paper or cutting out circular templates…….the list goes on.
While many of these solutions may help you estimate ring size, they will not guarantee you accurate ring size.
Visit our showroom to be expertly sized
If you can make the trip, we highly recommend visiting our Ryde showroom, where we provide free appointments—they’re in our mezzanine section.
If you can’t visit us, you can speak with us Monday to Saturday or order the service online.

If you’ve already placed an order for a ring, please let us know and we’ll provide this service free of charge as part of your order.
