Choosing an average finger size when you have no idea of her finger size

Many buyers opt for a common finger size when they have no idea what size to buy.  

A mid-sized ring is easier to adjust from a midpoint. Choose a suitable style for adjustment. For example, an engagement ring with plain shoulders.

In addition, choose a simple claw setting. Remember, engagement rings go onto the third finger of the left hand.

Best engagement ring styles for guessing her finger measurement.

If you’re, like many guys, uncertain of the finger measurement, you should consider a style of engagement ring that can be adjusted. The most common engagement measurement might not be your perfect choice. For this reason, you should choose a style of ring that is easy to re-size. For example, a ring design with a plain band.

In addition, choose a regular claw or prong setting. In other words, choose a design suitable for size adjustments.

Also, don’t choose a thin band. Resizing a ring thins the band at the back. As a result, a thin band offer less metal to work with. In situations where the band is far too thin, we often remake rings either partially or fully.

Is it better to guess larger or smaller?

Many guys opt for a size they know will be larger than her finger. The reasoning here is that she’ll be able to wear the ring. Going too small means she’ll be less likely to get it past her knuckle.

The chances are, if you have no idea, it will need re-sizing. For this reason, we routinely do this at no further cost. We merely ask clients to cover the small return cost of the postage.

Is there such a thing as a normal finger size?

There is no such thing as a ‘normal’ measurement. We are all built very differently. For example, so of us have short, fat, fingers. In contrast, others have long, thin fingers.

Some of our clients worry about big knuckles. Conversely, other clients struggle with small knuckles. In addition, temperate and body fluids affect how tight rings feel. Finger sizes change through the seasons.

For example, many buyers experience loose-fitting rings in Winter.

Despite sizing tools, we strongly recommend checking your size with a professional jeweller. At the same time, try on rings and find a size comfortable for daily wear.

Plus, sizes for Women’s fingers.

Please note that some clients require a larger band to the maximum available on our website. After reading our ring size guide, arrange a professional jeweller to measure your ring finger. After you find out your ring size, contact us for a plus-size personal quote. We measure ring size using the UK size system but happily work with other systems, such as US finger sizing.

Getting your ring resized

Most jewellers offer a service to resize your wedding rings if they become too small or too large. Remember, diamond settings and engravings can create issues when it comes to resizing.

Size adjustments are not typically expensive, but the cost can increase if multiple rings are worn. For example, when three rings are worn as a set. In other words, engagement, wedding, and eternity rings are worn on the same finger as a set.

If a ring cannot be adjusted for size, your ring might need to be re-made in the new, correct size.
