Selecting the correct ring size is an important detail that ensures both comfort and a proper fit. A well-fitted ring should not be too tight or too loose. This guide provides a convenient solution for determining your ring size at home using our clear and reliable ring size chart.
The process is simple. Use a ring you already own and compare it to the circles on the chart, or measure your finger using a strip of paper or a piece of string. Once you have the inner diameter in millimeters, refer to the chart to identify the corresponding US ring size.
This chart is based on the US ring sizing system, which is commonly used by most jewelry retailers both in-store and online. Knowing your US ring size can help streamline the purchasing process and prevent sizing errors, especially when ordering from international sources.
Most women’s ring sizes typically fall between size 5 and size 7, with size 6 being the most frequently selected. The included women’s ring size chart provides guidance for identifying the most suitable fit. If the specific finger being measured is unclear, the ring finger size guide offers additional assistance.
Finger size may vary slightly depending on the time of day and external temperature. For the most accurate results, it is recommended to measure your finger in the evening when the hands are warm and relaxed. Measurements taken when fingers are cold may lead to an undersized fit. Ensure the ring can pass over the knuckle comfortably while remaining secure on the finger.
This chart is designed for individuals seeking a fast and precise method to determine ring size. It is suitable for both first-time users and those verifying sizing prior to making a purchase. The US ring size layout, along with a dedicated women’s sizing guide, makes it easy to find the perfect fit.
How to Use the Ring Size Chart
- Print the chart or view it on your screen.
- Place a ring you already wear over the circles in the image.
- Match the inside edge of the ring to the circle that fits perfectly.
- The number inside the circle is your US ring size.
If you don’t have a ring to compare, you can wrap a string or strip of paper around your finger, measure it in millimeters (mm), and compare the measurement with our chart below.
