Find your ring size

Choosing the right ring size is crucial for comfort and security. Whether you’re buying a ring as a surprise or for yourself, it’s important to get the size right the first time. This guide provides detailed methods to measure your ring size accurately at home, ensuring you find the perfect fit.

Method 1: Using Our Downloadable Ring Sizer

Step 1: Download the Ring Sizer

Download Printable Ring Sizer

Step 2: Print the Ring Sizer

Print the ring sizer at 100% scale (do not use the “fit to page” option). Ensure accuracy by measuring the scale on the printout with a ruler.

Step 3: Use the Ring Sizer

For Existing Rings: Place your ring over the printed circles on the sizer. The circle that fits perfectly within the inside edge of your ring is your size. Make sure the ring aligns exactly with the inner edge of the circle to ensure an accurate measurement.

Method 2: Manual Measurement Using String or Paper

If you don’t have a printer, you can still accurately measure your ring size.

Step 1: Gather Your Tools

A piece of non-stretchy string or a thin strip of paper
A ruler with millimeter (mm) markings
A fine-tip marker or pen

Step 2: Measure Your Finger

Wrap the String or Paper Around Your Finger: Ensure it fits snugly but isn’t too tight.
Mark the Overlap Point: Use a marker to indicate where the string or paper overlaps.
Measure the Length: Lay the string or paper flat and use a ruler to measure the distance from the start to the marked point.

Step 3: Find Your Ring Size Using the Chart Below

Use your finger’s circumference measurement to determine your ring size from the chart:

Additional Tips for Accurate Sizing

Measure at the Right Time: Your fingers can change size throughout the day. Measure your finger at the end of the day when your fingers are at their largest to ensure the best fit.
Consider Knuckle Size: If your knuckle is larger than the base of your finger, you may need to size up. Measure both your knuckle and the base, then choose a size that fits comfortably over your knuckle.
Double-Check: It’s a good idea to measure multiple times to ensure accuracy.

Why Accurate Sizing Matters

Getting the correct ring size ensures that your ring is comfortable to wear and stays securely on your finger. A ring that’s too tight can be uncomfortable and difficult to remove, while a ring that’s too loose may slip off and get lost. By following these methods, you can confidently determine your ring size at home and ensure your new ring fits perfectly.

Talk about engagement!

From start to finish, James and Irisa were unbelievable. Irisa looked after me and guided me throughout the whole process and putting up with my constant emails and questions. The ring came out better than I could’ve imagined! I’m sure that was the true reason she said yes.

Thank you James and Irisa for everything.

A delighted customer

I am beyond words upon receiving my beautiful black opal ring. It is exactly how I envisaged and what the photos/videos Irisa sent me. Absolutely stunning! Their designs are so unique and that was the main reason why I went ahead with them.

Irisa has been such a pleasure to deal with. Efficient and professional. The whole process was such a great experience thanks to her.

I can’t recommend them highly enough. Thank you James and Irisa, for creating a piece of “superpower” for me.

I’m completely in love with my emerald eternity ring. The French fishtail setting adds such an elegant, vintage touch—it’s delicate yet secure, and the way it lets the light in around each emerald is just stunning. The stones are beautifully vibrant, and the craftsmanship is flawless. It’s everything I hoped for and more. Thank you for bringing this dream piece to life.

Subtle yet sparkling

Absolutely gorgeous! I purchased as a new everyday wedding band for an active lifestyle so my wedding set (also from James and Irisa) doesn't knock on everything. The band is lovely and makes a statement without being huge. Great quality as always too.

Amazing!

James and Irisa were amazing every step of the way when designing and making my fiancés engagement ring. We ended up making significant changes to the original design and they were very accomodating. The ring is gorgeous and very well made. My partner and I love it and wouldn't change a thing. Highly recommend!

I couldn't have dreamed of a more perfect engagement ring. The yellow diamond is absolutely radiant—so full of warmth and sparkle—and the unique cluster design makes it feel like a one-of-a-kind treasure. The craftsmanship is exquisite, and it feels incredibly meaningful to wear something so thoughtfully made. I still catch myself staring at it in the sunlight. Thank you for making this moment even more magical.
