How to Measure Your Ring Size
Simple methods to find your perfect ring size at home
Finding your correct ring size is essential for comfort and security. Below are several reliable methods you can use at home to determine your ring size.
Method 1: String or Paper Strip
What You'll Need:
- A piece of string, strip of paper, or floss
- Pen or marker
- Ruler (mm)
- Scissors
Steps:
- Cut a strip of paper about 4 inches (10cm) long and 1/4 inch (0.6cm) wide, or use a piece of string or floss of similar length.
- Wrap it around the base of the finger you want to measure. Make sure it's not too tight or too loose.
- Mark the point where the paper or string overlaps to form a complete circle.
- Measure the length from the end to your mark in millimeters. This is your finger's circumference.
- Use our Ring Size Converter to find your ring size based on this circumference.
Tip: Measure your finger 3-4 times to ensure accuracy, especially at different times of the day as your finger size can change.
Method 2: Using an Existing Ring
What You'll Need:
- A ring that fits the intended finger well
- Ruler (mm) or caliper
- Our printable ring size chart (optional)
Steps:
- Find a ring that fits well on the finger you want to measure.
- Measure the inside diameter of the ring in millimeters. Place the ring on a ruler and measure the distance from one inner edge to the opposite inner edge.
- Alternatively, download our Printable Ring Size Chart and match your ring against the circles until you find a perfect fit.
- Use our Ring Size Converter to find your ring size based on this diameter.
Tip: Make sure the ring you're using as a reference fits comfortably—not too tight and not too loose.

Tips for Accurate Measurement
- Measure when your fingers are at normal temperature - Cold fingers are smaller, while hot fingers are larger.
- Measure at the end of the day - Fingers tend to be largest in the evening.
- Consider the width of the band - Wider bands feel tighter than narrow bands of the same size. You might need to go up a size for wider rings.
- Account for knuckle size - If your knuckle is significantly larger than the base of your finger, measure both and choose a size in between.
- When in doubt, go larger - It's easier to size a ring down than to size it up.

Measurement Questions
Printable ring size charts can be accurate if printed at 100% scale and used correctly. However, for the most accurate measurement, we recommend visiting a jeweler or using a professional ring sizer.

Finger size can change throughout the day due to temperature, activity level, and diet. Fingers tend to be larger in the evening and when warm. It's best to measure your ring size at different times of day.
The ring finger is traditionally the fourth finger of the left hand in many Western cultures. However, some cultures wear wedding rings on the right hand. The choice of which hand to wear a ring on is largely cultural and personal.
