How to Find Your Ring Size
There are several ways:
- By using a ring size stencil
- By using a string or dental floss to measure the finger
- By measuring the diameter or circumference of an existing, well-fitting ring
How to Measure Your Ring Size With a Stencil
A ring size stencil simplifies measurements. The stencil is a thin sheet of plastic, cardboard or paper that has holes of different sizes. Each hole is marked with the appropriate number.
First, find the type of stencil to print out online that suits your style. There are a number of printable stencils online that are easy to use in finding the right size for the applicable ring finger. If you have the ring, simply place the ring on the spot where the paper has the appropriate size and, voila, you have your size. If you don’t have the ring, take a piece of string or paper and wrap it around the finger that needs to be sized. Mark the spot where the paper meets, then lay the string or paper on the stencil to get an estimate.
How to Find the Correct Size Without a Ring
You will have to resort to a few little tricks. The measurement method using a string or dental floss is popular. Find some string that is at least the length of a palm. Tie it around the root of the selected finger and make a knot around it. The string should be as close as the ring will be. Not too loose, but not too tight either. The knotted loop must also be able to be pushed over the joints of the finger. Cut the loop close to the knot and use a ruler to measure the length of the loop in millimeters. Depending on the jeweler or dealer, you may have to change the length to a different measurement.
When measuring, please consider these tips:
- Measure the ring finger of the correct hand.
- Measure in the evening or after light sporting activities.
- Measure on days when the recipient is hydrated.
- Do not measure when the recipient is cold.
- Be careful when taking measurements. Remember, even the most skilled jewelers need precise numbers.
- For gifts, choose a ring that is slightly bigger. It is easier — and less costly — to size down a ring than up.
- Observe the shape and width of the finger. These features can also influence the final result.
- Measure more than once and on different days to get a more accurate result.
- When in doubt, get advice from a trusted jeweler.
Determining Ring Size With an Existing Ring
If you already have a well-fitting ring, the size is easier to determine.
Measure the inside circumference: Cut a small strip of paper. Roll it in length and place it in the opening. The paper strip should cover the entire inner circumference. Use a sharp pencil to mark the point where the strip overlaps. Then remove the paper strip to measure the length of the strip to the mark with a ruler.
Measure the inside diameter: Alternatively, the diameter can be used to determine the size. Using a ruler, measure the widest part of the ring from one inner edge to the opposite inner edge and enter that value into the ring size calculator above.

FAQ About Ring Sizes
How to secretly determine ring size?
If you want to purchase a ring as a gift or a surprise engagement, for example, you have a tough task ahead. But, if you don’t want to be too obvious, measuring the inside diameter of another existing ring of the intended recipient can be the answer.
Can Rings Be Tightened or Made Wider?
Despite careful measurements, the finished ring may be too tight or too wide. It can then be changed. To this end, the professional will use two methods: It will either be stretched, or, in case of a major difference, the ring will be opened, and additional material will be added. In the case of making the ring tighter, it can be worked with a machine. It is also possible to remove a piece of the material.
Whether the procedures are applicable to your ring depends on whether and how well the ring was filled with stones and the material from which it was made. Gold and platinum are usually easy to change, but stainless steel represents a greater challenge. Gemstones or diamonds can lose their hold with the changes made, which is why they may have to be re-inserted. Engravings sometimes have to be completely recreated.
How much does it cost to have a ring sized?
If a ring is too tight or too wide, a professional can stretch out the metal, for example, or work on shrinking it with a machine. In case of a major difference, it is also possible to add or remove a piece of the band material. Cost varies drastically depending on the metal the ring is made of, how much of it needs to be sized, and how design elements of the ring will affect the new size. And, even experienced jewelers can make mistakes, so take your time, measure wisely and choose a trusted professional. It could be anywhere from $20 to hundreds of dollars to resize a ring, depending on these and other factors.
