Ring Size: How to Find Your Fit in 3 Simple Ways
Armando Poggi Guide
Choosing the right ring size is simpler than it seems. Whether you're buying a ring for yourself or for a special someone, this guide provides three practical methods for measuring your size: two you can do comfortably at home, and one at our boutique in Via Calzaiuoli.
Why
The Right Size Makes All the Difference
A ring that's too loose risks slipping off and getting lost, while one that's too tight is uncomfortable to wear and remove. Unlike a bracelet or necklace, a ring has no adjustment margin: that's why it's worth taking a few minutes to carefully measure your size before choosing your next piece of jewelry.
Reference NumbersMost Common Sizes in Italy
If you haven't measured your size yet but need a general idea, here are the most common values:
These are just general indications: fingers vary greatly from person to person, so we always recommend measuring the exact size with one of the methods below before making a purchase.
In Three StepsHow to Find Your Ring Size
Use a Ring You Already Wear
The most reliable way: take a ring that fits well on the finger for which you are buying the new ring (not too tight, not too loose). Place it on a ruler and measure the internal diameter, which is the distance between the two inner edges of the ring, in millimeters.
Use a ring from the same finger for which you are buying the new one — different fingers and hands often have different sizes.
Use a String or Paper Strip
If you don't have a reference ring, wrap a thin string (or a strip of paper) around the base of your finger, mark the point where it overlaps, then measure the length with a ruler: this will give you the finger's circumference in millimeters.
Measure your finger in the evening, when fingers are slightly more swollen than in the morning, to avoid choosing a size that is too tight.
Have it Measured Directly in Store
If you prefer a professional and immediate measurement, the easiest way is to visit us in store: one of our experts will measure your size in a few seconds with sample rings, so you have absolute certainty before choosing. This is also the most elegant solution if you need to give a gift and are not entirely sure of the size: we can advise you on the best choice and, if necessary, adjust the size after purchase.

How to determine a woman's ring size?
The most accurate way is to measure the internal diameter of a ring that already fits well, or the circumference of the finger with a string or paper strip, and convert the data using a size chart. Alternatively, a jeweler in-store can measure it with a sample ring in a few seconds.
What size is 12 for a ring?
Size 12 is one of the most common sizes for women in Italy. The exact value in millimeters (diameter or circumference) varies slightly depending on the measurement standard used by the brand: always check with the converter for the specific brand you are interested in.
What does my ring size correspond to in centimeters?
Ring sizes are generally expressed in millimeters of internal diameter or circumference, not in centimeters. If you have measured your finger in centimeters, multiply by 10 to get millimeters and compare the data with the conversion chart.
Are sizes the same for all brands?
No. Each brand (Armando Poggi, Pandora, and other brands we carry) may have its own numbering system. This is why our converter asks you to select the brand first: the same numerical size can correspond to slightly different physical measurements from one brand to another.
