5 Top Tips for discreetly finding their ring size

So many people surprise their partner with a proposal yet how can you surprise them with a ring that will actually fit?

It would be a tad awkward if you were to get down on one knee only to realise that the ring doesn’t fit past their first knuckle. So to make sure this doesn’t happen, here are the steps we take to determine your partner’s ring size:

1. Using their current rings as a guide

If you can get a ring that you can bring into the appointment, that’s great. The best ring would be worn on their ring finger on the right hand.  If you can bring in a ring, it is very important to know what finger they wear it on as each finger can be up to two sizes different.

2. A photo of their current ring on YOUR finger

If you can’t ‘borrow’ the ring for your appointment, then pop it on your little finger and take a photo showing up far up your finger the ring goes. We can then compare this photo with rings in my studio.

3. General details about your partner

If you can’t get a hold of any of their rings, when you come I’ll ask your partner’s height, weight, body shape. Certain information such as what sport they play or do they lift weights will allow me to make an educated guess based on my experience in taking people’s ring sizes, and generally, I’m never more than a size off.

Diamondport will resize the ring complimentary after the proposal if the ring doesn’t fit.

4. Photos are even better

In addition to hearing specific details about your partner seeing recent photos will also be a huge help. If you’re reading this in advance, sneak a full-length photo of your fiancé followed by a close up of their hands.

5. Engagement ring vs wedding ring sizing

This sizing difference does depend on the shape of her finger. A wedding ring will always be worn on the inside of the engagement ring which sometimes does mean the wedding ring is slightly bigger. At Diamondport, we will determine your size at our wedding ring consultation.

Ring sizing around the world can get complicated really quickly. Worse than international shoe sizing, there still is no ultimate standard for ring sizing, which is why we put together this handy guide (we use ourselves!) to help you out if you’re looking to buy jewellery and are not sure on the size.

As always, if you have any questions, don’t hesitate to contact us.
