What you need to know when measuring your ring size

So you’re thinking of buying a new ring. Congratulations! One of your decisions will be choosing a ring size for your special piece. It should be as easy as taking a measurement, and off you go, right?

Not quite.

Here are three key things to know when deciding what ring size will be best for you, especially if you’ve never worn a ring day-to-day before.

1. Your ring size changes season to season.

How hot or cold you are changes your ring size. In warmer weather, your hands will swell a little, making rings feel tighter. In colder weather, your fingers will be smaller.

When you consider that a ring sizes are only around 0.5mm apart in diameter, it doesn’t take an awful lot to affect the fit of a ring. You’ll need to find a happy medium where your ring isn’t too tight in summer, nor too big in winter.

2. Your ring size changes throughout the day.

Aside from seasonal fluctuations, your finger size also changes throughout the day depending on your environment, your activities, and your unique body. For example, you may wake with puffier fingers in the morning which settle in the afternoon. Your fingers will be larger when you exercise, and smaller when you’re restful.

Choosing a size that will be comfortable most of the time takes some judgement.

3. The width of your ring changes the size you need.

Not all rings of the same size will feel the same. For example, an 8mm wide band will be tighter than a dainty 3mm wide band, even if they’re exactly the same size. You’ll need a larger size in an 8mm ring compared to a 3mm wide ring in order for it to feel comfortable.

Take this into account when stacking rings too. A 2mm ring that feels comfortable on its own may feel too tight when worn with another ring or two stacked with it. So when you’re choosing a ring to add to a custom ring stack, or one that will eventually be part of an engagement ring, wedding ring and eternity ring set, worn together on the same finger, be sure to consider the size you need.

So, which ring size should you choose?
