How to Measure Your Ring Size at Home – 3 Easy Ways
Buying an engagement or wedding ring is exciting, but choosing the right ring size can be a concern for many. It is crucial that the ring fits perfectly: too small will pinch, and too large risks falling off. This guide will help you easily determine your correct ring size at home.
In Finland, engagement and wedding rings are traditionally worn on the ring finger of the left hand. Please note that the ring finger of the right hand is typically larger than that of the left hand, so it's very important to try on the ring on the correct finger.
Measuring Ring Size | How to Determine Your Ring Size
Finding the right ring size can sometimes be a bit challenging, but it's worth taking the time to do so. Many factors influence finger size, such as the time of day, air temperature, and diet. It's important to find the right size as it directly affects comfort.
Method 1: Measuring ring size with tape or string
You can measure your finger's circumference with tape, for example. When measuring with tape, you should take a strip of paper 3-4 mm wide, wrap it tightly around your finger, and mark the circumference with a pen. This will tell you your finger's circumference. You can also measure the circumference with a piece of string.
Method 2: Measuring ring size from an old ring
If you already have a suitable ring, you can find out its size by measuring the inner diameter of the ring. The inner diameter measurement (in mm) is also your ring size. You can easily measure the ring size with calipers, but you can also measure the ring with a ruler.
Method 3: Measuring ring size with a ring sizer (Most accurate)
You'll get the most accurate measurement by having your finger measured at a jeweler. Since it's best to measure your finger over several days, you can also order a ring sizer separately from an online store. A ring sizer will give you a significantly more accurate measurement than tape or paper.
There are different types of ring sizers. At its simplest, a ring sizer is a wide plastic strip that wraps around the finger. The strip has a pre-made size chart, and by tightening the ring sizer around your finger, it will show you the appropriate ring size.
Ring Size Chart (Circumference and Diameter)
Below is a ring size chart. Finnish ring sizes are given according to the inner diameter of the ring. If you measured your finger's circumference (Method 1), the table below tells you what diameter size it corresponds to.
| Finger Circumference (mm) | Ring Size (Diameter mm) |
|---|---|
| 47.1 mm | 15.0 |
| 48.7 mm | 15.5 |
| 50.2 mm | 16.0 |
| 51.8 mm | 16.5 |
| 53.4 mm | 17.0 |
| 55.0 mm | 17.5 |
| 56.5 mm | 18.0 |
| 58.1 mm | 18.5 |
| 59.7 mm | 19.0 |
| 61.2 mm | 19.5 |
| 62.8 mm | 20.0 |
| 64.4 mm | 20.5 |
| 65.9 mm | 21.0 |
| 67.5 mm | 21.5 |
| 69.1 mm | 22.0 |

How do I know if the ring is the right size?
A properly sized ring should fit snugly enough not to fall off when you move your hands around. However, the ring should still be loose enough to be pulled over the knuckle relatively easily. If you have to struggle to get the ring off your finger, it's too small. You'll quickly get used to wearing a ring, and after a short period of use, a well-fitting ring will no longer feel tight on your finger.
Consider these 4 things when choosing a ring size:
- Finger size variation: Finger size varies. In the evening, fingers are often thicker than in the morning. Temperature also affects it: in summer, fingers are thicker than in winter. Measure your finger a few times on different days and at different times of day to get a reliable result.
- Effect of ring type: A wider ring (over 6 mm) will feel tighter than a thin ring. When buying a wide ring, it's advisable to choose a size 0.25 - 0.5 larger.
- Shank shape: Rings with a rounded inner surface (so-called "comfort fit") slide on the finger more easily, and you can choose a slightly snugger size for them.
- Center of gravity: In a solitaire ring, the center of gravity is high. A snugger fit helps keep the ring in place and prevents it from spinning on the finger.
How can I secretly find out my partner's ring size?
A surprise proposal is a lovely idea, but finding out the size secretly is challenging. Here are a few tips:
- The easiest way is to "borrow" a ring your partner wears on that specific finger and measure its inner diameter (Method 1).
- If they don't have a suitable ring, you can try comparing their fingers to yours. Is their ring finger as thick as your pinky? Measure your own finger and estimate based on that.
- Ask for help from your partner's friends or family.
I'm buying a ring as a gift. What if the size is wrong?
No need to worry. The size of most gold and silver rings can be adjusted. We offer goldsmith services, such as ring enlarging and ring reducing.
Note: Not all rings can be resized. For example, titanium, steel, and ceramic rings are too hard to modify. Alliance rings (where diamonds encircle the entire band) also cannot be resized.
FAQ - Frequently Asked Questions about Ring Size Measurement
A correctly sized ring is snug but comfortable. It should be tight enough not to fall off when you wave your hand, but loose enough to be slipped over the knuckle without much effort. If you have to struggle to get the ring off, it's too small.
The choice depends on the width of the ring. If you are buying a wide ring (over 6 mm), choose the larger size. If the ring is very narrow and thin, choose the smaller size. In Finland, there are more cool months, so it is often safer to choose a size that will not fall off your finger in cool weather.
The easiest way is to "borrow" a ring your partner wears on their left ring finger and measure its inner diameter with a ruler. If there isn't one, you can try measuring their finger while they're sleeping or ask a friend for help.
