Making sure you get a perfect fit when purchasing a ring online can be challenging. How do you know if your sizing method is accurate? What's the most accurate ring sizing method?

This page is a resource to help take the stress out of ring sizing. Follow the steps below and if you still have questions then send me a message, I’d love to help you find your perfect fit.

(A) I have absolutely no idea what size I need!

No problem! Send us a message, include your full name and address, and we will send you standard ring sizing gauge set. Plan to wear a ring that is 5mm wide or more? Then you will also need to proceed to Step 2 (below).

(B) I have been sized at a jewelry store and they used a ring gauge set.

Great! This method is fairly accurate, however the ring sizing kit most jewelers use consists of a set of very narrow metal or plastic ring gauges. Ring width impacts fit, so if you plan to purchase a ring with a width of 5mm or more, then it's essential that you try on a ring at that width too. Please proceed to Step 2 (below).

(C) I have been sized at a jewelry store and tried on rings in the width I'd like to order.

Top marks to you! If you visited a jewelry store in person, and you tried on rings (metal or wood) at the width you wish to order, then we can be 99% sure you have the right size. Grown Rings are made to US sizing standards, and unless the rings you tried on were incorrectly sized or labeled, your Grown Ring will fit the same way. The one caveat is that our finger size can change throughout the day. If you think your fingers might swell during the day, then it's a good idea to use 3D printed sizing rings, that you can wear for a full day/night (or two!). Want to be 100% sure? Click here for Step 2 (below).

D) I sized myself using a printable ring sizing tool, or piece of paper or string, or a plastic pull-tie/belt sizer, or a ruler, or a silicone ring. (Or I just guessed!)

The not so good news is that all of these methods are not often accurate. The good news is that you are proactive and adventurous and we have a good approximation of your ring size. Flexible materials (whether it's paper, plastic or silicone) do not give an accurate size for a rigid ring. Fear not! Proceed to Step 2 (below) to get your size.


3D-printed sizing rings are the most accurate way to determine your ring size. I offer a 3D printed ring sizing service that is guaranteed to give you an accurate ring size. For $9.95 (with free shipping) I'll custom print your desired ring sizes/widths, and I'll include a few other sizes just in case. The 3D printed rings are made from biodegradable plastic and are also great as they confirm size and width at the same time. 3D printed sizing rings also allow you to wear the ring for a few hours or a day (or a week!) allowing you to confirm that the fit stays comfortable in various conditions and times of the day. If you'd like to order a 3D printed ring set, please purchase the listing below through my Etsy store. Your 3D printed rings will ship out asap with an average eta of 5-7 days.

When checking out, just select one size (e.g.: 8mm, 8.5) and then at checkout there's a field called "Add a Note" where you can list any additional sizes/widths that you'd like to try.If you order 3D printed sizing rings (from me), and your ring does not fit, I will resize it (or replace) it free of charge.


As I make each and every ring to order, I can offer quarter sizing. If a size 10 is a little snug and a 10.5 feels just a little loose, then a 10.25 (10 1/4) might be your perfect fit. Think you might need a quarter size? I can print 3D-printed sizing rings in quarter sizes too.
