Buying a ring — whether it’s an engagement ring, a gift, or a treat for yourself — is exciting. But nothing turns that excitement into frustration faster than a ring that doesn’t fit. Getting your ring size right the first time saves you money, time, and the disappointment of a piece you can’t wear right away.
In this guide, we’ll walk you through everything you need to know about ring sizing: how to measure at home, what can throw off your measurement, and what to do if a ring doesn’t fit once it arrives.

Why Ring Size Matters More Than You Think
A ring that’s too tight can be uncomfortable or even cut off circulation. One that’s too loose risks slipping off and getting lost — which is especially heartbreaking with fine jewelry or a sentimental piece. Because most fine jewelry, including one-of-a-kind and antique pieces, isn’t mass-produced in every size, knowing your exact measurement before you buy makes the entire experience smoother.
How to Measure Your Ring Size at Home
You don’t need to visit a store to get a good estimate of your ring size. Here are three simple methods you can try today.
Method 1: The String or Paper Strip Method
Wrap a thin strip of string or paper around the base of your finger, where the ring would normally sit. Mark the point where it overlaps, then measure the length in millimeters with a ruler. Compare that measurement to a ring size conversion chart (see below) to find your size.
Method 2: Measure an Existing Ring
If you already own a ring that fits the intended finger well, measure its inner diameter in millimeters and match it against a conversion chart. This method tends to be more accurate than the string method since it accounts for the natural curve of the finger.
Method 3: Use a Printable Ring Sizer
Many jewelers offer free printable ring sizers you can download, cut out, and use at home. If you’d like one, feel free to contact us and we’ll send you a printable sizer, or you’re welcome to stop by our showroom in Thornhill for an exact, professional measurement.

Factors That Can Affect Your Ring Size
Your finger size isn’t always constant — a few everyday factors can throw off your measurement.
Temperature and Time of Day
Fingers swell slightly in warm weather and shrink in the cold. They’re also typically a little larger later in the day. For the most accurate reading, measure at room temperature, in the evening.
Dominant vs. Non-Dominant Hand
Your dominant hand is often slightly larger than the other. Always measure the exact finger on the exact hand you plan to wear the ring on.
Finger Shape and Knuckle Size
If your knuckle is noticeably larger than the base of your finger, you may need a ring with a slightly looser fit to get it past the knuckle comfortably, or consider a design with a spring-loaded shank.


Buying an Engagement Ring as a Surprise?
This is the trickiest sizing scenario, since you can’t exactly ask them to try it on. A few reliable tricks:
- Borrow a ring they already wear on the correct finger and bring it in for us to measure (they’ll never know it was gone)
- Ask a close friend or family member who might know or can casually find out
- When in doubt, size slightly larger — a ring that’s a touch loose is easier to resize down than one that’s too tight
What If the Ring Doesn’t Fit? Our Resizing Policy
We understand that even careful measuring can be off by a little. That’s why we’re upfront about resizing on every ring listing: each product page notes whether that specific piece can be resized, and by how much. Because many of our rings are one-of-a-kind and antique pieces, resizing options vary from ring to ring based on the design and setting.
If you’re unsure before purchasing, message us directly and we’ll confirm sizing and resizing options for the exact piece you’re interested in.
