How To Find Out Your Ring Size
Your best bet for getting your exact ring size would be to go to your local jeweler, ideally the one who will be sizing your ring. You can get your approximate ring size from home, though, and here’s how:
- Cut a piece of paper into a long thin strip.
- Wrap the piece of paper around your knuckle, since this is the largest point that the ring will have to be able to get over.
- Mark where the two ends of the paper first overlap with a marker.
- Measure the length with a ruler.
- Use this conversion chart to determine what your approximate ring size is.

FAQ: Most Asked Ring Sizing Questions
Do you have a ring sizing related jewelry question? Send your questions to me on Twitter using the hashtag #ringsizingfaq.
How is a ring sized down?
To size a ring down, a small section of the shank is removed, and then the ring is shaped down and soldered back together. After ring re-sizing, the stones will have to be retightened due to the ring being pulled down. There is a limit to how much you can resize a ring because if the prongs are pulled too much, the stones will not be able to be retightened, and they will keep falling out.
Do they add more gold when they make my ring a bigger size?
Sometimes yes and sometimes no. If the ring only needs to go up less than a 1/4 of a size and there is a thicker shank, the jeweler may be able to bump your ring up on a ring mandrel with a jeweler’s hammer. This is not a common practice. Usually, the ring is sized up by adding a small piece of gold or platinum, soldering the ring back together, then polishing the edges to a smooth finish.
Why don’t I get gold back when I size a ring down?
The amount of gold that is taken out of a ring is usually so minuscule that it wouldn’t make sense to give it back because it would be of no use to you and of very little value. Also, sometimes the ring has to be filed down where they are removing the gold, turning the gold into a fine dust that gets sucked up with a vacuum. Sizing a ring is very labor intensive. Any gold that the jeweler may acquire based on ring sizing is factored into the price. Sizing a ring down the cost significantly less than sizing a ring up because the jeweler would have to add gold to the ring on an upsizing.
Why is it more expensive to size some rings than others?
Pricing on ring sizing is usually dependent on the number of sizes the ring needs to be adjusted as well as the weight and type of metal.
Platinum is more expensive to size than gold because it takes more heat and more care to size platinum. It is also usually more expensive to size stones that need special care. For instance, only diamond, sapphire, and ruby can take the heat of a soldering flame. All other stones either need to be removed, buried or covered, or they need the use of a laser to weld the ring back together because if these stones are heated, they will be scorched and essentially ruined.
The extra care and equipment needed for these stones will raise the cost.
I got my ring sized at two different stores, and my finger was a different size at each. Why?
Jewelers size out rings and fingers using ring mandrels and ring sizers. Depending on what these pieces are made of and what company made them, there is a slight variation from one company’s sizes to the next. The variation is usually between a 1/4 and a 1/2 of a size. It is important to try to get your true ring size at the jeweler that is going to be sizing your rings. Fingers can also change their size within a 1/4 or a 1/2 of a size and sometimes, even more, depending on the weather or other factors. Fingers can swell up depending on the season, time of the month, your diet, or if you have just had a strenuous workout.
