While a professional fitting is always available, there are simple ways to measure your ring size from home. This guide walks you through the most reliable methods, shares expert tips for getting the most accurate result, and answers the most common questions our clients ask. By the end, you’ll feel confident choosing the size that's right for you.
Three Easy Ways to Find Your Ring Size
Measure with String or Paper
This quick, no-fuss method uses items you already have at home. It’s ideal for getting a fast and fairly accurate measurement.
What you’ll need: a piece of string or a narrow strip of paper, a pen, and a ruler that measures in millimeters.
-
Wrap the string or paper around the base of your finger where the ring will sit.
-
Use the pen to mark the point where the ends overlap.
-
Lay it flat and measure the length with your ruler.
-
Match your measurement to the corresponding size on our ring size chart.
Expert tip: Measure your finger at the end of the day, when it’s at its largest. Avoid cold temperatures, since they can temporarily shrink your fingers and result in a smaller reading.
Use a Printable Ring Sizer
Printable ring sizers are a reliable way to find your size from home, especially if you prefer a guided measurement. All you need is access to a printer and a little attention to detail.
How to use it:
-
Find a printable ring sizer online from a trusted source.
-
Make sure to print it at 100% scale so the measurements stay accurate.
-
Cut out the sizer and wrap it around your finger as directed to find your size.
Bonus tip: Many printable sizers include sizing circles. If you already have a ring that fits, place it over the circles to see which one matches the inside edge.
Expert tip: Print on heavier paper like cardstock so the sizer holds its shape as you measure. For best results, take the measurement when your fingers are warm and relaxed.
Match an Existing Ring to a Size Chart
Already have a ring that fits the finger you're shopping for? This method is quick, accurate, and requires minimal tools, just a ring and a sizing chart.
How to do it:
-
Find a ring size chart online with true-to-scale sizing circles.
-
Place your ring flat against the chart and align it with the printed circles.
-
The correct size will match the inside edge of the ring exactly without showing space around it.
Expert tip: Make sure your printer settings are set to 100% scale before printing the chart. A few millimeters can make a big difference in how your ring fits.
This method works best with rings that have a consistent circular shape and a thinner band. If you're using a wider style, you may want to confirm with an additional method.
Tips for an Accurate Ring Size
Finding your ring size isn’t just about the number. Comfort, fit, and lifestyle all play a role in choosing the size that feels just right. These tips will help you get the most accurate result and ensure your ring fits beautifully from day one.
How a Ring Should Feel
The right fit should feel natural on your finger, snug enough to stay in place, but loose enough to slide over your knuckle with a gentle twist. If it glides on too easily or spins throughout the day, it might be too big. If it feels tight or gets stuck going on or off, you may want to size up slightly.
Wider bands tend to feel tighter, while thinner bands offer a bit more flexibility. Take the ring’s style into account when deciding between sizes.
What to Do If You're Between Sizes
If your measurement falls between two sizes, it’s usually best to size up. A slightly larger ring can always be adjusted or resized later, especially if you’re working with one of our in-house jewelers.
You can also consider the style of the ring. Stackable bands and wider silhouettes may feel more snug, while slim bands may give you more breathing room. Comfort is always the goal, so trust your instincts, and don’t hesitate to reach out if you’re unsure.

Understanding Ring Sizing
When it comes to ring sizing, there’s more behind the numbers than you might think. Here's what to know about how sizing works, how it’s measured, and what those numbers mean across different styles and people.
Are Ring Sizes Unisex?
Yes. Ring sizes are based on the internal circumference or diameter of the band, not on gender. A size 7 is a size 7, whether it’s worn by someone who identifies as female, male, or nonbinary.
At Greenwich St. Jewelers, we believe jewelry is for everyone. Many of our designs are unisex by nature or available in a range of sizes and styles that work beautifully across a wide variety of hands. Our team is always here to help you find a piece that fits both your finger and your style.
Average Ring Sizes for Women and Men
While fingers vary widely from person to person, most people fall within a few common ranges.
-
The average ring size for women is typically between size 5 and 7.
-
For men, the average range is between size 9 and 11.
That said, there’s no right or wrong size. A snug fit on one person might feel loose on another. The best way to find your size is to measure, test, and adjust as needed until it feels just right.
Ring Size FAQs
Can my phone measure my ring size?
There are apps that claim to measure ring size using your phone, but they’re not always reliable. If you try one, double-check the result against a printed size chart or physical method for the most accurate fit.
How do I make sure my ring is the right size?
A ring should slide on easily and come off with a slight pull. It should feel secure at the base of your finger without pinching. If it spins often or feels too tight at different times of day, you might need to adjust the size.
What size is my existing ring?
If you have a ring that fits well, you can match it to an online sizing chart. Place it on the printed circles and find the one that lines up with the inside edge of the band. Make sure the printout is to scale for accuracy.
Can a ring be resized?
Many rings can be resized, depending on the design and materials. Engagement rings, wedding bands, and most solid gold or platinum styles can typically be adjusted by a jeweler. Intricate or eternity bands may have limitations, so it’s always best to ask.
What if I’m buying for someone else?
If it’s a surprise, try borrowing a ring they wear on the same finger and use the sizing chart method. You can also enlist a friend or family member to help. When in doubt, choose a size that’s slightly larger. We offer resizing on many styles, so adjustments can be made after the moment has passed.
