How do I measure my ring size at home?

Wrap a thin strip of paper or string around the base of your finger, mark where it overlaps, and measure the length in millimeters. Compare this circumference to a ring size chart. For best accuracy, measure at the end of the day when fingers are slightly larger.

What is the average ring size?

The average ring size for women is US 6 to 6.5 (16.5–16.9mm diameter), and for men it is US 9 to 10 (18.9–19.8mm diameter). However, ring sizes vary widely, so always measure rather than guess.

Should I size up or down if between sizes?

If you are between two sizes, it is generally better to size up, especially for wider bands (over 4mm), as wider rings fit more snugly. A slightly loose ring is easier to resize than one that is too tight.

Do fingers change size throughout the day?

Yes, fingers can swell by up to half a size due to heat, exercise, diet, and time of day. Measure your ring size in the evening at room temperature for the most accurate fit.

How do international ring sizes convert?

Ring sizing systems vary by country. For example, US size 6 equals UK size L, EU size 51, and 16.5mm inner diameter. Always use a conversion chart when ordering internationally, and confirm whether the retailer uses inner diameter or circumference.

Tips for Accurate Sizing

Measure multiple times

Take measurements at different times of day and average the results for the most accurate size.

Consider time of day

Fingers are typically smaller in the morning and can swell in heat or after exercise. Measure at different times.

Measure the correct finger

Each finger can be a different size, even on the same hand. Measure the exact finger you'll wear the ring on.

Account for ring width

Wider bands (6mm+) typically require going up half a size for comfort.

Should be snug, not tight

Your ring should slide over your knuckle with slight resistance but feel comfortable once on.

When in doubt, size up

It's easier to size a ring down than up.

Sneaky Sizing Tips

• Borrow a ring they wear on the correct finger and trace it
• Ask a friend or family member who might know
• Compare their finger to yours or a friend's hand who will discreetly tell you their size
• Size 6 or 6.5 is a safe guess for most women
• When in doubt, go slightly larger - easier to size down
