Ring size can be tricky, since finger size can change depending on a variety of factors – like the season, weather, time of day, diet, medication, etc. Then the width and shape of the ring can also affect the ring fit. This is why it's common for a wedding or engagement ring to be re-sized at least once to get the fit dialed in for that particular ring.
We offer one free re-sizing per ring, on band rings without stones, up to 1/2 size (larger or smaller), within 90 days of receiving the ring. You are only responsible for shipping both ways. Beyond that, rings can be re-sized for a fee, or you can take it to a jewelry repair shop to have it re-sized locally. Be sure to contact us first before sending a ring back to be re-sized.
When getting sized, it's always best to get sized by professionals using metal ring sizers before ordering a ring. We recommend getting sized several times, by different people, on different days before ordering a ring. That way, you can come up with a sort of average.
We do not recommend using printable ring size charts, as they are very inaccurate. Mostly because a piece of paper or string conforms to the shape of your finger (which isn't round) in a way that a metal ring will not. Also, if you wrap a string around your finger, then measure it, you are likely to stretch it differently when wrapping it around your finger, or when measuring it on a ruler. And even a fraction of a millimeter off will make for a ring that is too big or too small.
Some things to consider when getting sized:
- Fingers are typically bigger in the morning when you are hot, or have recently consumed a lot of salt or alcohol.
- They shrink when you are cold or swimming in cold water.
- They are bigger in the summer and smaller in the winter.
- Fingers can swell a lot when you sleep or fly.
- Wider bands fit more snugly than narrow bands, so the width of the ring sizer will affect the size. Generally, if sized with a narrow ring sizer, you would want to size up 1/4 size for rings 5-6mm wide and 1/2 size for rings 7-8mm wide.
- Bands with a flat interior will fit tighter and be harder to slide over the knuckle than bands with a comfort-fit interior.
- Ideally, you want to be sized with bands that are the same width and fit as the ring that you are getting.
A ring is sized by measuring where the bottom of the ring lines up, or where the ring touches the wider part of the mandrel. The ring in this photo is a hair smaller than a size 6. If this was a wide band, the top of the ring might line up around 5.5 or 5.25, but it is the bottom of the ring that the size is determined by. If it is a comfort fit band, then it is sized from the narrowest part of the inside of the band.
Another way to size a ring is by using calipers and measuring the inside diameter of the ring. This is a more precise way to measure a comfort fit band. In some European countries, ring sizes are given as the inner mm diameter, which is really the most accurate way to size a finger and ring.
If you are relatively sure of your ring size but want to double-check it before you order your ring, contact us about getting brass rings to try. For a small fee, we will send you a brass ring in the ring size that you request plus one 1/2 size larger and one 1/2 smaller - in the approximate width of the ring you plan on ordering. Something to note is that the interior of these rings is flat, but a comfort-fit ring will fit differently than one with a flat interior. So the home try-on brass rings are mostly useful if you are planning on ordering a ring with stones since those are more difficult and expensive to re-size. Another option is to mail us a ring that fits your finger well and we can determine what size it is.
