Best engagement ring styles for guessing her finger size

If you’re like many guys, uncertain of finger size, you should consider a style of engagement ring that can be sized. The most common engagement ring size might not be the perfect choice for you. For this reason, you should choose a style of ring 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.

Is it better to guess for engagement ring size larger or smaller?

Many guys opt for a size that 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 really 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’ ring size. 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 fluid affect ring size. 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.
