Measure A Ring
- Select a ring that already sits well on the finger where you plan to wear your new piece.
- Determine the inner diameter of that ring with a ruler or tape measure. Make sure your ruler displays millimeter (mm) markings, then lay the ring flat over the ruler and read the measurement across the interior opening — this is the surface that rests against your skin.
- Refer to the Ring Size Chart below to match your diameter reading to the corresponding ring size.
Several environmental and bodily conditions can influence how a ring fits, so it is worth accounting for these before settling on a size. As a general rule, if you are estimating your partner’s ring size, it is better to err on the larger side — resizing a ring smaller is far simpler than enlarging it.
Average Ring Sizes
As a helpful benchmark, women’s ring sizes in India typically fall between 9 and 14, whereas men’s sizes generally range from 17 to 22 (India). When no other sizing details are available, selecting within these standard ranges is your safest option.
The best time to take a finger measurement is during the evening hours. Fingers naturally swell throughout the day and tend to be at their widest by nightfall, while they are usually slimmer in the morning. Taking the measurement in the evening helps ensure a consistently comfortable fit.
Optimal Temperature
Temperature has a noticeable effect on finger size. Cold weather causes fingers to contract and become slimmer, while warm or humid conditions make them expand. For the most accurate measurement, avoid sizing your finger in extreme heat or cold.
Fingers Expand And Contract
A number of additional factors can temporarily increase finger size, including physical activity, fluid retention, pregnancy, the natural aging process, and arthritis. Conversely, weight loss and exposure to cooler temperatures can cause fingers to become smaller.
Thicker bands
Wider ring bands (those exceeding 6mm) tend to feel snugger on the finger. We recommend choosing half a size larger when opting for a thicker band to maintain a comfortable everyday fit.
