Most men guess their ring size and get it wrong. The ring arrives, it either jams at the knuckle or slides off the finger entirely, and the return process erases any satisfaction from the purchase. The mistake is not in the buying. It is in skipping a two-minute measurement that any person can do at home with a strip of paper and a ruler.
This guide covers three ways to measure your ring size accurately at home, the Indian size system with a full chart, what to do if you land between sizes and how finger choice affects the number you need.
How ring sizes work in India
India follows the Indian/Asian size system, which runs numerically: size 6 through size 30, with each step representing a 0.5mm increase in internal diameter. This is different from the US system (which runs 1 through 13 in fractional increments) and the UK system (which uses letters: J, L, N and so on). Most jewellery sold in India, including all Drippin'gear. rings, uses Indian sizing.
The number itself corresponds to the internal circumference of the ring in millimetres, not the diameter. A size 16 ring, for example, has an internal circumference of roughly 51.5mm and an internal diameter of approximately 16.4mm. This is why knowing your size as a number without context is not enough. If you are shopping across different stores, always cross-check against the diameter in millimetres. That is the number that does not change between sizing systems.
Three ways to measure your ring size at home
Method 1: The string or thread method. Take a thin strip of string, thread or dental floss and wrap it snugly around the base of the finger you intend to wear the ring on. Mark the point where the string overlaps with a pen. Lay the string flat against a ruler and measure the length in millimetres. That number is your internal circumference. Use the chart below to find the corresponding Indian size.
Method 2: The paper strip method. Cut a strip of paper roughly 5mm wide and 8–10cm long. Wrap it around the base of your finger. Mark where the paper overlaps, then measure the marked length against a ruler. This method tends to be slightly more accurate than string because paper does not stretch. The measurement you get is the circumference. Match it to the chart below.
Method 3: Measuring an existing ring. If you own a ring that already fits correctly on the target finger, place it on a flat surface and measure the internal diameter (the distance straight across the inside of the ring) using a ruler or digital calliper. Match that diameter in millimetres to the chart below. This is the fastest and most accurate method if the reference ring fits well.
One note that applies to all three methods: measure at the end of the day, not first thing in the morning. Fingers are slightly larger in the evening due to warmth and activity. A ring sized in the morning can feel tight by the afternoon.

Half sizes and fit — what to do if you're between sizes
If your measurement lands between two sizes, go up, not down. A ring that is slightly loose is always more comfortable and safer than one that is too tight. A tight ring restricts blood flow to the finger. In a warm Indian climate, fingers expand over the course of a day and a ring that felt fine in the morning can become genuinely uncomfortable by the evening. The marginal looseness of sizing up is far less of a problem than the discomfort of sizing down.
There is also a practical reason to go up: the ring still needs to clear the knuckle. Even if the ring fits the base of the finger well, a ring that is too small will not pass over the knuckle on the way on or off. If your knuckle is noticeably wider than the base of your finger, measure both and size for the knuckle rather than the base. The ring will sit slightly looser at the base, but it will go on and come off without effort.
Different fingers, different sizes
Most men assume all their fingers are roughly the same size. They are not. The index finger and ring finger on the same hand can differ by a full size or more. The ring finger is almost always narrower than the index finger on most men. The middle finger is typically the widest of the three central fingers. The pinky is its own size entirely and often requires a size significantly smaller than the rest.
The practical instruction here: measure the specific finger you intend to wear the ring on. Do not use a ring that fits your index finger to estimate the size for your ring finger. Take two minutes and measure the actual finger. If you plan to wear a ring on both hands, measure the dominant hand separately. The dominant hand's fingers are often slightly larger due to use and muscle development.
How sizing works for Drippin'gear. rings
All rings on Drippin'gear. are listed in Indian sizes. Each product page includes the available sizes and, where relevant, a note on whether the band is wide or narrow. Wide bands typically require going up by one size because they cover more of the finger and create additional pressure at the point of contact. If a product description notes a wide band, factor that in when sizing.
If you are between sizes or unsure, the size guide on each product page is the right reference point. You can also reach out directly before placing an order. The goal is a ring that you wear daily without thinking about it. That only happens when the fit is right from the start.
