Measure More Than Once
Finger size can change slightly throughout the day. Measure more than once and avoid sizing when your hands are unusually hot, cold, or swollen.
Finding the correct ring size is an important part of ordering a ring that fits comfortably. Whether you're purchasing a memorial ring, wedding band, or another keepsake, this guide will walk you through a few simple ways to determine your ring size.
If you're unsure, a local jeweler can usually measure your finger in just a few minutes, or you can use one of the methods below at home.
There are several easy ways to determine your ring size. Whether you visit a local jeweler, measure a ring you already own, or use our printable ring size guide, these methods can help you choose the size that's right for you.
The most accurate method is to have your finger professionally measured using a ring sizing tool. Most local jewelry stores provide this service quickly and often at no charge.
If you have a ring that fits the intended finger well, measure its inside diameter and compare it to our sizing chart.
Download and print our ring size guide at 100% scale, then follow the included instructions to compare your finger or an existing ring to the sizing chart. You can also contact us for a Free Ring Sizer.

Get the most accurate fit
Ring sizing is simple, but small details can affect the fit. Taking a little extra time before ordering is especially important for personalized and memorial rings that may have limited resizing options.
Finger size can change slightly throughout the day. Measure more than once and avoid sizing when your hands are unusually hot, cold, or swollen.
A wide band can feel more snug than a narrow ring in the same size. If you are between sizes, consider the width and shape of the specific ring before ordering.
The ring should pass over your knuckle without excessive force while still fitting securely at the base of your finger.
Measure the finger and hand where the ring will actually be worn. The same finger on your opposite hand may be a different size.
Prefer a physical sizing tool?
Jewelry Keepsakes offers a complimentary ring sizer that we can mail to you upon request. It is an easy option if you would rather confirm your size at home before placing your order.
Using the printable guide
Print the sizing guide at 100% or Actual Size. Printer scaling can change the ring circles enough to give you an incorrect measurement.
The line shown above is designed to represent 2 inches (50.8 mm). When using the downloadable sizing guide, verify its printed calibration mark with a physical ruler before measuring your ring or finger.
Especially important for memorial jewelry
Confirm the size before personalization or custom production begins.
Ask whether the selected metal and design can be resized.
Permanently Sealed rings and some contemporary metals may have resizing limitations.
Engraving, stones, resin, or other custom details may also affect future resizing options.
If you are uncertain, request our free ring sizer or visit a local jeweler before ordering.
