HOW TO MEASURE
There are several ways to estimate your ring size at home. For the best result, take more than one measurement and compare your results.
The easiest method when you already own a ring that fits correctly.
Choose a ring that fits the exact finger and hand you are shopping for. Print our sizing guide at 100% scale and place your ring over the sizing circles.
Find the circle that most closely matches the inside edge of your ring.
No existing ring? Use the finger sizer included in our PDF.
Print the guide at actual size, cut out the sizing strip, and carefully cut the marked slit.
Insert the pointed end through the slit and wrap the strip comfortably around your finger. The indicated number will give you your approximate US ring size.
You can also estimate your size using the circumference of your finger.
Wrap a narrow strip of paper or nonstretch string around the base of your finger. Mark the point where the ends meet.
Measure the length in millimeters and compare your measurement with the chart below.

Ring measurements can vary slightly between sizing systems and manufacturers. For custom jewelry, wide bands, or valuable rings, professional sizing is recommended.
BEFORE YOU CHOOSE
Even a fraction of a size can make a noticeable difference. Keep these details in mind before choosing your final fit.
The same finger can differ slightly between your left and right hand. Always measure the exact hand where the ring will be worn.
Wider bands generally feel tighter than thinner bands. Depending on the design, a slightly larger size may provide a more comfortable fit.
Fingers can temporarily expand in heat and shrink in cold conditions. Measure when your hands are comfortable and at a normal temperature.
Finger size can fluctuate throughout the day. Take several measurements and look for a consistent result before choosing your size.
Your ring needs to pass over the knuckle while still fitting comfortably at the base of your finger. If your knuckle is noticeably larger, consider both measurements.
Certain ring styles may fit differently depending on the width, profile, and construction of the band. Professional sizing can help account for these differences.
KEEPING IT A SECRET?
If you can discreetly borrow a ring they already wear on the correct finger, bring it to Ali Jewelers and we can help determine its approximate size.
You can also ask someone close to them who may already know their ring size. If neither option is possible, common starting sizes are often around 6 to 7 for women and 9 to 10 for men, although individual sizing varies considerably.
THE BEST WAY TO KNOW
At home measurements are a great starting point, but professional sizing is the best way to determine the right fit, especially for engagement rings, wedding bands, wide bands, and custom jewelry.
Visit Ali Jewelers and we'll help you determine your ring size before you make your final decision.
The perfect ring deserves the perfect fit.
