Ring Size Chart

A simple and accurate way to measure ring size at home, this method can be paired with the string method: Wrap a string around the ring finger, and compare it to the printable ring sizer.

1. Print the ring sizer image. Make sure the scaling of the page is set to 100%. If you know your ring size, measure and compare to ensure it is accurate.
2. Measure the 3½ inches with a ruler or measuring tape to ensure the printout is precisely to scale.
3. Trim the paper to match the outline and cut a slit as indicated by the vertical line.
4. Insert the pointy tip of the paper through the slit.
5. Place the paper around the ring finger and gently tug until you have a secure, comfortable fit. 
6. Read your result by finding where the number line meets the slit. This indicates the ring size.
7. Consider repeating steps 4-6 a few times to ensure accuracy.

Here, we cover three tried-and-true methods for getting the right ring size so you’ll be able to get a proper measurement for the most important ring your partner will ever wear. We have included a printable ring size chart that you may find helpful.

If you are shopping for engagement rings, secretly “borrow” and measure a ring that fits the left-hand ring finger (if they are right-handed, it is likely that the left-hand ring finger is smaller). Then you can easily measure with a ring sizer or tape measure and buy the same size.

Tread carefully — you don’t want them to find out, and you definitely don’t want to lose the ring accidentally! Depending on how much time you have with the ring before they notice it’s gone, here are a few tactics to help find the accurate ring size:

If you have a few hours, take the ring to a local jeweler to determine the correct ring size for the left ring finger. While this takes some time, it’s also the most accurate way to measure the proper fit.

To accurately and quickly determine the correct size yourself, purchasing or borrowing a ring mandrel (also called a ‘ring sizer’) is a reliable and accurate option to get the perfect size. A mandrel is a tapered rod that is labeled with ring sizes. Simply slide the ring down the mandrel — the line where the ring stops indicates the ring size.

Be sure to print our ring size guide ahead of time and use a tape measure or ruler to double-check that it is precisely to scale. You can use it to measure your ring size first so that you know it is accurate. Move the ring from circle to circle until you find the best match for the ring’s inside circumference. If the ring lands between two sizes, always choose the larger one.

Carefully trace the inside and outside of the ring on a piece of paper. Repeat several times for added accuracy. Take the paper to a jeweler for a size estimate.

Alternatively, you can use the string method by tying a piece of string to the same size as the ring, and compare it to a ring size chart.

If pressed for time, take your partner's existing ring and try it on your own fingers to see if one of them fits well. If it does, you can measure that finger's ring size later to figure out the perfect fit.

Enlist the help of a close friend or family member who may already know your partner's ring size or can assist you in executing the other methods.

Make sure this is someone you can trust with your secret! Here are a few questions to ask:

If they have similar-sized hands, they could try each other’s rings for fun and gauge the right size in the process. Knowing the most common women's ring sizes — 6-6.5 — can also help find the right ring size.
