Should Your Wedding Ring Be the Same Finger Size as Your Engagement Ring?

Should your wedding ring fit the same?

During our many face-to-face appointments, future brides often show uncertainty about what ring size to order. Buyers frequently ask how big their wedding ring should be compared to their original engagement ring. Should the wedding ring be the same size? Should the wedding ring be larger? Or should you go a half, or full size smaller?

Begin with your engagement ring size and fit

Your first step is to confirm the existing size of your engagement ring. Most jewellers will drop your ring onto a sizing stick, taking the reading (typically) on the leading edge of the markings. In the UK, this will be determined by a letter, possibly followed by an increment of a half size if it is slightly larger.

Is your engagement ring size tight, loose or just right?

Next, establish if your current engagement ring size is correct. The fit should be snug without being too tight. In addition, there should be no excessive bulging of the skin beneath the ring. If your ring is too loose, it will likely spin around on the finger, not staying in place. We recommend adjusting your engagement ring at this stage to fit correctly.

Choosing your wedding ring fit compared to your engagement ring size

If your engagement ring is correctly sized, we recommend matching your wedding ring size so that both rings are the same finger size. If your engagement ring is slightly too snug, a small increase in half-a-finger size will also work. This will provide a little more room when both rings are in place.

Why does the fit feel tighter with both rings in place?

If your engagement ring and wedding ring feel too tight when worn together, this is likely due to the combined width of both rings. For example, a 2.5mm wedding ring will feel looser than a 5mm wedding ring. When our clients experience this problem during a final fitting, we recommend getting both rings adjusted slightly. This is often by just half a size or less. As a result, both rings sit more comfortably on the finger. 

Therefore, on occasions when the width is a lot bigger compared to the engagement ring eg. 5mm, 6mm upwards, we offer a sample size loan in your chosen width. 

Diamond set bands 

Wedding rings with added sparkle, such as fully set with diamonds, or partly set with diamonds, can be impossible (full set) or difficult if a large difference is required. Previously bespoke diamond wedding bands that have been crafted to fit with our clients’ engagement rings perfectly that are also wide. We have cast the ring itself and invited our client to try on for fit before we set the diamonds. 

This avoids any discomfort with the fit and the width of the ring once the ring is completed. With any size adjustments being made beforehand, avoid any further issues when the ring is set with diamonds.

Should you fuse your wedding ring with your engagement ring?

This is something we have done in the past by request. Very few clients have both rings fused (by a process similar to welding). This can be done to prevent your rings from moving against each other. Fine detail such as a milgrain edge, or micro-claw settings can be worn away by constant friction between rings. Fusing can be a solution to prevent excessive wear in this way. The disadvantage is no being able to wear each ring independently.

Interlocking and bespoke wedding rings

Our bespoke design option is also available for fitted and shaped wedding rings. Popular with clients whose engagement rings are unusually styled and unable to fit with a straight wedding ring. Some finished interlocking ring sets are so unique that for this, we also recommend and suggest going for the same fingersize as the engagement ring. This is to ensure the rings don’t rub or get stuck together if the size is vastly different.

In Summary – getting your wedding ring size correct.

If you are choosing a wide wedding band, consider a slightly larger size if your existing engagement ring is a comfortable / snug fit.

A traditional width (approx. 2.5mm) wedding ring should fit comfortably with an existing engagement ring of the same finger size.

A half size larger will provide a little more room if your existing engagement ring is already snug.

If both rings, ordered in the same size feel too tight, have them both adjusted and re-finished at the same time.

Insist on a final fitting some weeks before your wedding date. Don’t cut things too fine to ensure sizes are perfect for the big day.
