Does the right size cause difficulties?
Measuring ring size easily and accurately
Measuring at home can be done accurately in the following ways
1) Caliper
Measure the inner diameter of an old but suitably sized ring with a caliper as shown in the image below.
Note! Check that the old ring is round. A twisted ring will give an incorrect result.
Calipers can be purchased affordably at hardware stores.
2) Ring size
- Insert the rounded end of the measuring tool through the hole under the magnifying glass and pull it through
- Place the gauge on the desired finger and tighten it so that it is snug but still comfortable
- Pull the ring gauge back to the joint. The gauge should also fit over the joint (sometimes the joint is the widest part of the finger)
- When the gauge fits well, read the number from under the magnifying glass on the band. Note! the number is best seen in good natural light, for example, next to a window.
Interpretation of measurement results
In Finland, the commonly used measurement standard indicates sizes such as 17 mm or 17.5 mm. This specifies the inner diameter of the ring in millimeters. An even more commonly used unit of measurement in Europe indicates sizes like 54 or 56. This indicates the length of the inner circumference of the ring, or the thickness of the finger, in millimeters.
In the table below, you can see the equivalence of these measurement units. In the Taika Helsinki online store, both of these ring measurement units are provided for each ring. The smaller value is the inner diameter (mm), while the larger value is the inner circumference (mm), or the finger's circumference.
Inner diameter / Inner circumference
- 16.0 mm = 50 mm
- 16.5 mm = 52 mm
- 17.1 mm = 54 mm
- 17.7 mm = 56 mm
- 18.3 mm = 58 mm
- 19.0 mm = 60 mm
- 19.7 mm = 62 mm
- 20.4 mm = 64 mm
Note! finger size varies constantly:
- In the morning and again in the evening, fingers are usually swollen, as well as in hot weather or after eating salty food.
- In the middle of the day and in cold weather, fingers are at their smallest.
- The best time to try on a ring is in the middle of the day, in a warm room.
