Methods to Determine Your Ring Size
Here are two reliable methods to measure your ring size, addressing the question, “How do I measure my ring size at home?”
1. Use an Existing Ring
For those asking, “How do I know my ring size for an engagement ring?” this method works if you have a well-fitting ring.
-
What You’ll Need: A ring that fits the intended finger and a ring size chart or printable sizer.
-
Steps:
- Place the ring on a printable ring size chart (available here).
- Match the inner circle of the ring to the closest circle on the chart.
- Note the corresponding size.

3. Visit a Professional Jeweller
For the most accurate sizing, we highly recommend visiting a local jeweller.
-
How It Works: Jewellers use a set of sizing rings or a mandrel to measure your finger or an existing ring.
-
Benefits: This method accounts for finger shape, knuckle size, and ring width, ensuring precision.
-
Tip: Schedule your visit later in the day when fingers are slightly swollen for a more accurate fit.
How to Secretly Determine Ring Size?
If you’re planning a surprise, such as an engagement, you may need to determine ring size discreetly. Here are three effective methods:
- Borrow a ring the recipient wears on the intended finger (e.g., the left ring finger for an engagement ring) and use the existing ring method above.
- Another way to secretly determine ring size is using a bar of soap and an existing ring. When you have a window of opportunity, take a ring which she wears on her fourth finger and press it into a bar of soap until it creates an impression. Then you can measure the inner diameter with a ruler and compare it to a ring size chart. And, don't forget to clean and return the ring to its original place.
- If possible, consult a friend or family member who might know their size or can subtly find out.
What to Do If You’re Between Sizes
What if my ring size is between sizes? If you were visiting an off-the-shelf jewellery, we would recommend opting for the larger size for comfort; especially for wider bands, which feel tighter. However, because all of our jewellery is made-to-order, you don't have to worry - we design to your exact specifications so we know you Saint Stone ring will fit perfectly!
Factors That Affect Ring Size
Finger size can fluctuate due to:
-
Temperature: Fingers swell in heat and shrink in cold.
-
Time of Day: Fingers are often larger in the evening.
-
Knuckle Size: If your knuckle is larger, the ring must fit over it but not be too loose at the base.
- Ring Width: Wider bands require a slightly larger size for comfort.
We recommend measuring your finger under normal conditions (room temperature, midday) for the best results.
Things You Shouldn’t Do When Measuring Ring Size
To ensure accuracy, avoid these common mistakes:
-
Don’t Use String or Paper: String, floss, or paper strips can stretch, twist, or compress, leading to inaccurate measurements. Even non-stretchy materials are hard to keep consistent, often resulting in a size that’s too large or small. Additionally, this method doesn't account for the knuckle size which the ring has to slip over. For most people, the joint is larger than the rest of the finger.
-
Don’t Measure Cold or Swollen Fingers: Cold weather or post-exercise swelling can skew results. Measure when your hands are at a normal temperature.
-
Don’t Ignore Knuckle Size: A ring must fit over the knuckle, so account for it when measuring.
-
Don’t Rely on One Measurement: Take multiple measurements at different times to confirm consistency.
-
Don’t Use an Incorrectly Scaled Chart: Printable sizers must be printed at 100% scale, and online tools should be from reputable sources.
-
Don’t Assume All Fingers Are the Same: Ring sizes vary between hands and fingers. Measure the specific finger the ring is for.
