How to Measure Your Ring Size at Home

Finding your perfect ring size is quick and easy. With a few simple household items, you can measure your finger in just a few minutes and shop with greater confidence.
What You’ll Need
• A ribbon, string, yarn, or thin strip of paper
• A pen or marker
• A ruler with a centimeter (cm) scale
Step 1: Wrap the String Around Your Finger
Gently wrap the ribbon, string, yarn, or strip of paper around the base of the finger where you plan to wear your ring.
The material should fit snugly but comfortably. It should not be so tight that it presses into your skin, but it should be snug enough to reflect the way a ring will fit. Make sure the measurement can also comfortably pass over your knuckle.

Step 2: Mark Where the Ends Meet
Using a pen or marker, make a small mark where the end of the string, ribbon, or paper overlaps the remaining length.
Step 3: Measure the Circumference
Remove the string and lay it flat against a ruler. Measure from the end of the string to the mark, using the centimeter (cm) side of the ruler.
This measurement represents the circumference of your finger.
Step 4: Determine Your Ring Size
Use your finger's circumference measurement to determine your U.S. ring size.
For example:
• 5.0 cm (50 mm) ≈ U.S. Ring Size 5.5
• 5.5 cm (55 mm) ≈ U.S. Ring Size 7
• 6.0 cm (60 mm) ≈ U.S. Ring Size 9
• 6.5 cm (65 mm) ≈ U.S. Ring Size 11
• 7.0 cm (70 mm) ≈ U.S. Ring Size 13
• 7.5 cm (75 mm) ≈ U.S. Ring Size 15
Because ring sizing can vary slightly by measurement method, finger shape, and ring style, use these measurements as a guide and refer to our ring size chart whenever possible.
Helpful Tips for Getting the Best Fit
✨ Measure at room temperature. Cold temperatures can make your fingers smaller, while heat can cause them to swell.
✨ Measure later in the day. Fingers often become slightly larger throughout the day, which can provide a more practical measurement.
✨ Measure more than once. Take two or three measurements to make sure you get a consistent result.
✨ Consider your knuckle. If you have larger knuckles, make sure the ring size is large enough to comfortably pass over them.
✨ Between two sizes? If your measurement falls between standard sizes, choosing the larger size is often more comfortable, particularly for wider bands.
✨ For the most accurate fit, consider having your finger professionally measured by a jeweler.
That's it! With just a few simple household items, you can quickly estimate your ring size and shop with confidence. 💍
