Buying a ring—especially a high-value piece of jewelry like those in 950 silver from flames army®—requires precision. The most common mistake when shopping online is not knowing exactly how to choose my ring size, which can lead to frustration and delays.

We have prepared this essential guide to help you measure your finger accurately, ensuring that your men's ring fits perfectly. Follow these steps to find the right size and receive your jewelry without any hassle.
Reliable methods for measuring your ring size at home
There are two main methods you can use with simple tools. Remember that measurements are in millimeters (mm), the basis of our size chart.
The existing ring method: The most accurate option
If you already own a ring that fits the desired finger perfectly, use this method:
- Take the ring and place it on a ruler or caliper.
- Measure the inner diameter of the ring, from inner edge to inner edge. Be precise, as a difference of one millimeter can be a full size.
- Write down the measurement in millimeters and compare it with our flames army® Size Chart (below).
The paper and ruler trick: Measure your finger's circumference
If you do not have a ring to use as a reference, use a strip of paper or a piece of string:
- Cut a thin strip of paper (or use a non-stretchy piece of string).
- Wrap the strip firmly around the widest knuckle or the base of the finger (you should be able to slide it over the knuckle).
- Mark the point where the paper overlaps.
- Measure that length (the circumference) with a ruler.

Avoid mistakes: Factors that affect your ring size
Temperature and time of day: The impact on measurements
Temperature can cause your fingers to expand or contract. Measure your finger when it is at a normal body temperature (neither too cold nor too hot). The best time is at the end of the day, when fingers are slightly more swollen.
Special tips for wide rings
Our men's 950 silver rings often feature wide, thick designs. Wide rings tend to feel tighter than thin ones. If you are buying a bulky design (wider than 8 mm), consider ordering a half size larger.
flames army® Size Chart: Conversion between national and international measurements
Once you have the measurement in millimeters (diameter or circumference), use our conversion chart. In Colombia, the most common men's size ranges from 10 to 12 (US size), but this varies greatly.
Diameter (mm) to size conversion chart
| Inner Diameter (mm) | Size (Approx.) | US Size (Reference) |
|---|---|---|
| 18.0 mm | 8 | 7.5 |
| 18.9 mm | 9 | 9.0 |
| 19.8 mm | 10 | 10.5 |
| 20.7 mm | 11 | 12.0 |
Comparison with US sizes (the international reference)
Our chart uses the US system as an international reference, as it is the most standard in 950 silver jewelry. If you already know your US size, you can shop with complete confidence at flames army®.
