Ordering a ring can be tricky if you're unsure of your exact ring size. While jewelers can provide precise measurements, visiting them isn't always convenient. Fortunately, you can accurately measure your ring size at home. Use a soft measuring tape to measure your finger and convert the measurement using a ring size chart or ruler. If you already own a well-fitting ring, the process becomes even simpler. You can determine your size by comparing your ring to a ring size chart.
Steps
Measure Your Finger

Wrap a soft measuring tape around your finger. Ensure it fits snugly around the knuckle, the widest part of your finger that the ring must slide over comfortably. Generally, putting on and removing the ring shouldn't cause discomfort. Use a fabric or plastic measuring tape for the most accurate results. While a metal tape can work, it’s harder to wrap around your finger and may cause injury.
- For easier measurement, print a ring size guide from a jewelry store's website. Use it like a measuring tape, but the units will already be in ring sizes, eliminating the need for conversion.
- Avoid wrapping the tape too tightly. Measure for a snug but comfortable fit.
- Fun fact: fingers on the same hand can vary in size. Measure the exact finger you plan to wear the ring on. For engagement rings, measure the ring finger on your left hand, not the right.
- Your finger size changes throughout the day. Sounds strange, right? For the best results, measure at the end of the day.

Record the measurement where the tape overlaps. Use a piece of paper and a pen or pencil. You can measure in inches or millimeters, depending on the store you plan to order from. Many places use both, but in Europe, they might only use millimeters.
- If you're using a ring sizer, mark the overlapping point directly on the tool.

You can find this chart on many jewelry store websites. If you prefer, you can print it for convenience, though it’s not mandatory. The chart converts finger measurements to ring sizes; for example, a measurement of 2.34” (about 59.5mm) corresponds to a size 9 ring.
- If your measurement falls between two sizes, choose the larger one.
- If using a ring sizer, mark the overlapping point to determine your size.
Use a circular ring size chart

Find and print a ring size chart. Many online jewelry stores provide these charts, displaying circles of various sizes. For accuracy, use the chart from the store where you plan to purchase the ring. This ensures the sizes on the chart match their product sizing.
- A resized chart can lead to incorrect measurements, meaning the ring you order might not fit. To avoid this, ensure your printer’s scaling feature is disabled.

Find a ring you already own that fits the finger you’re measuring. Choose one that fits snugly—comfortably tight but not too tight. Make sure the ring fits the specific finger you’re measuring; your ring fingers on each hand might differ in size!

Place the ring over the circles on the size chart. The circles correspond to the inner diameter of the ring, helping you find the perfect fit. If the measurement falls between two sizes, opt for the larger one.
Tips
- Certain metal rings cannot be resized, while others have limited adjustability. Consult your jeweler if you have any questions or concerns.
- Fingers may swell during pregnancy or due to certain medications. Keep this in mind when measuring your ring size.
- Most jewelry stores charge a one-time fee for resizing, even if multiple adjustments are needed later.
- If purchasing a wedding ring, check if it’s a comfort-fit design. These rings are more comfortable to wear but may require a different size. Discuss this with your jeweler before making a purchase.
