One of the greatest advantages of handmade silver jewelry is that each piece fits your finger perfectly. However, to experience this, you need to know your correct size. As 935 by Roberto Bravo, we have been producing handcrafted silver rings for over twenty years, and the most frequent question we receive from our customers is "how can I measure my size at home?" In our content titled "How to Calculate Ring Size," we have transformed the professional ring sizing methods applied in our workshop into steps you can easily follow at home… What to Consider When Taking Ring Size? There are three basic rules for measuring silver rings: measuring at the right time, with the right technique, and from the right part of the finger. The thickness of your finger can vary by 0.5-1 mm throughout the day. Your fingers are thinner when you wake up in the morning and slightly swollen in the evening due to water retention in the body. If you measure between 5:00 PM and 8:00 PM, your ring will fit comfortably both in the morning and in the evening. The second rule is temperature. A measurement taken with cold hands in winter will be 1-2 sizes too small in summer. Before measuring, wash your hands with lukewarm water and let them rest at room temperature for a few minutes. Similarly, do not measure after exercise or contact with hot water; the temporary expansion may not be permanent. The third rule is the measurement point. Measure not the thinnest part of the finger, but the widest area just below the knuckle. The ring will pass through this point and then rest on a thinner area. How to Measure Ring Size at Home? Method 1: Diameter Calculation with an Existing Ring If you have a silver ring that you wear comfortably, this is the most accurate method: Place the ring on a flat surface. Measure the inner diameter using a millimeter ruler (do not include the thickness of the outer silver). Take the measurement from the widest point of the ring. For example, if the inner diameter is 16 mm, your ring size is 16. In Turkey, ring sizes are calculated based on inner diameter (mm). The margin of error in this method is minimal. Important note: If you are switching from a thin band ring (2-3 mm) to a wide band model (6-8 mm), you may need to go up half a size. Wide rings feel tighter on the finger. Method 2: Finger Circumference Measurement with Paper Strip or String If you don't have a ring to measure, the following method is effective: Take a thin strip of paper, string, or dental floss (thick string gives inaccurate results). Wrap it around the knuckle area of the finger where you will wear the ring. (Not too tight, keep it loose enough to slide a thin piece of paper underneath.) Mark the point where the two ends of the string meet with a pen. Unroll the string and measure the distance from the beginning to the mark with a millimeter ruler. This value is the circumference of your finger. Divide the circumference value by 3.14 (pi). The result gives you your ring size. Example calculation: Circumference: 52 mm → 52 ÷ 3.14 = 16.5 mm (approximately between size 16–17) In this case, you can choose size 17. Turkey Ring Size Chart and Conversions In Turkey, standard sizes are based on inner diameter (mm). However, some international brands use European or US sizes. The table below will help you calculate your ring size: TR Size (mm) Circumference (mm) US Europe 15.0 47 4.5 49 15.5 49 5.0 50 16.0 50 5.5 51 16.5 52 6.0 52 17.0 53 6.5 54 18.0 57 8.0 57 19.0 60 9.0 59 The most common size for women is 15.5 -16.5 mm, and for men, it is between 18–20 mm. However, hand structure is personal; if you want a precise measurement, you can get support from jewelry experts. How to Determine Size When Buying a Ring Online? If you are between two sizes when buying a ring online, choose the larger half size. Especially silver rings with a thickness of 5 mm and above fit tighter on the finger. If size 16 is comfortable for a thin model, a 7 mm thick ring for the same finger should be 16.5 or 17. Also, ring size can vary depending on the season. A ring bought in winter might feel tight in summer. In 935 by Roberto Bravo collections, silver ring models are prepared based on standard size ranges, and workshop support is provided for custom requests. For models prepared to order or subsequently adapted to the individual, returns are not possible as the production process is shaped by individual demand. How Many mm Should a Ring Size Be? It depends entirely on the structure of the finger. For women, ring finger size is between 15.5–17 mm, and for men's ring finger, it is between 18–20 mm. Sizes may vary depending on weight, body structure, and various conditions. The index finger is usually 1–2 sizes larger than the ring finger. The pinky finger is 2–3 sizes smaller. Since each finger has a different size, separate measurements should be taken. Are Women's and Men's Ring Sizes Different? Yes, men's finger structure is generally 2–4 sizes wider on average compared to women's. When making a selection, not only the design but also the size range is taken into account. To examine models prepared with this difference in mind in men's ring collections, you can browse 935 by Roberto Bravo men's jewelry models. Common Measurement Errors 1. Measuring the Middle of the Finger Instead of the Knuckle The measurement you take based on the thinnest part of the finger is misleading. The ring must pass through the knuckle, so you should measure from the widest area just below the knuckle. 2. Wrapping Too Tightly or Too Loosely When using string or a paper strip, leave enough space to slide a piece of paper underneath. If you wrap it too tightly, you will get a small size; if you wrap it too loosely, you will get a large size. 3. Measuring in the Morning Your fingers may be thinner in the morning. They swell slightly during the day, especially in the evening. Therefore, if you order based on a measurement taken in the morning, you may find the ring tighter in the evening. 4. Measuring in Cold Weather Your fingers contract in the cold. The measurement you take may seem larger than normal. How to Buy a Gift Ring Without Knowing the Size? If you are planning a surprise ring gift and don't know the other person's size: You can measure with a ring they have worn before. You can ask a mutual friend for help. Why Does Ring Size Change? Factors such as weight gain, weight loss, pregnancy, hormone therapy, water retention, and aging affect finger thickness. It is natural for your ring size to change over the years. There are also seasonal differences; your fingers are slightly swollen in summer compared to winter. The fingers of your dominant hand are usually 0.5 mm thicker than your other hand (for example, if your right hand is active, your right ring finger is slightly larger than your left). We recommend taking separate measurements for the right and left hands. Does Ring Size Change with Weight Gain? Yes, absolutely. A 5-10 kg change can affect finger thickness by 0.5-1 size. Your rings will feel tighter when you gain weight and looser when you lose it. If you experience large fluctuations in your body weight over the long term, we recommend having your rings checked periodically. Frequently Asked Questions About Ring Size At what time of day should ring measurements be taken? Evening hours (between 5:00 PM and 8:00 PM) give the most accurate results. At these times, your fingers are neither too swollen nor too thin. I'm between two sizes, which one should I choose? Choose the larger one. A ring that is too tight will cause discomfort and leave marks on your finger. A larger ring can be resized if necessary. Can I use the same size for my right and left hand? Generally, yes, but the fingers of your dominant hand may be 0.5–1 size wider. For accurate results, we recommend measuring both hands separately. Does the size change for wide rings? Yes. Rings with a thickness of 5 mm and above feel tighter on the finger. If size 16 is comfortable for a thin ring, you may need to get 16.5 or 17 for a wide ring. What happens if I make a mistake in online shopping? As 935 by Roberto Bravo, we offer free size changes for all orders. If your ring is too tight or too loose, you can send it to our workshop, and we will adjust it to the correct size. My ring has loosened over time, what should I do? Silver rings can expand very slightly with use. Resizing can be done in our workshop; this service is free for our customers. Does ring size change during pregnancy? Yes, during pregnancy, finger thickness can increase by 1-2 sizes due to water retention in the body. You will return to your old size after childbirth.
