Measuring ring size: Here's how to do it correctly

How do I measure my ring size?

When buying a ring, you want it to fit perfectly. Too large, and it constantly slips. Too small, and you’ll only get it off again with soap. Fortunately, there are a few simple ways to determine your ring size accurately, whether you use a professional ring sizer or everyday household items.

Method 1: Using a ring sizer (the most accurate option)

A practical option is a ring sizing tool that works like a small cable tie. It’s inexpensive, reusable, and easy to store. Simply place it around your finger, tighten it slowly until it feels comfortable, and read off the size. (Buy here)

The most accurate method, however, is a professional ring sizer. It looks like a small keyring with metal rings in every size. You simply try them on until one fits perfectly – not too loose, but not so tight that you worry about getting it off again later.

If you’re serious about rings, especially if you wear several, this is a worthwhile investment. You’ll use it again and again, and it’s also handy for measuring rings for friends. (Buy here)

Method 2: DIY with string or a cable tie

If you don’t have a tool at hand, a simple DIY method works just as well. Take a piece of string, wrap it once around your finger, and mark the point where it overlaps. Then measure the length in millimetres.

The same method works with a thin cable tie, which also allows you to test putting it on and taking it off.

Make sure to measure the finger on which the ring will actually be worn. Fingers vary in size, and they are usually slightly thicker in summer than in winter.

Pro tip for the perfect fit

Measure your finger in the afternoon or evening. In the morning, hands are often slimmer, which can result in a ring that feels too tight later on.

A perfect fit means the ring slides easily over the knuckle but stays securely in place when worn.

In the end

The more accurately you measure, the less likely it is that a ring ends up forgotten in a drawer because it simply doesn’t fit. And if you’re taking the time to choose a ring that can last a lifetime, it should feel right from the very beginning.
