What Is the Average Ring Size for Women and Men?

Sometimes you just need a sensible guess. Maybe you’re buying a surprise, or ordering online with no way to measure first. Averages won’t fit everyone, but they give you a reasonable starting point. Here are the typical ring sizes, and why you should still measure whenever you can.

The average ring size for women

Most women fall around a US 6 to 6.5. In other systems that’s roughly a UK L to M, an EU 52 to 53, and about 16.5 mm across the inside. The common range stretches from about a US 5 to a US 7, so if you have any extra clue, such as their height or build, lean up or down within that band.

The average ring size for men

Men most often land around a US 9 to 10.5, which is roughly a UK R to U, an EU 59 to 63, and around 19 to 20 mm across the inside. The usual range runs from about a US 8 to a US 12. Men’s hands vary more in width than women’s, so the average is a looser guide here.

A quick word of caution on these numbers: they lean toward the sizes sold in the United States, and they blend a lot of very different hands into one figure. Treat them as the middle of a wide spread, not a safe bet.

What moves someone away from the average

• Overall build. Taller, larger-framed people tend to have wider fingers, and finer-framed people narrower ones.
• Age. Fingers often thicken over the years, and knuckles can widen, which changes both the size and how easily a ring passes over the joint.
• Temperature and time of day. Fingers swell in heat and shrink in cold, and they’re usually largest by evening. More on that in why rings feel tighter on some days.
• Which hand. The dominant hand often measures a touch larger.

Why the average is only a starting point

Ring sizes span a wide range, so a gift bought purely on the average has roughly a coin-flip chance of fitting well. The good news is that measuring takes a couple of minutes. If you can get hold of a ring they already wear, or a moment with their hand, you can do far better than the average. Our guide to finding a ring size without asking covers the sneaky methods, and the how to measure guide covers the direct ones.

Turn a measurement into any size

Once you have a number, whether it’s a US size, a millimetre reading, or a letter, the ring size converter translates it into every other system, and the full ring size chart shows the whole range at a glance. If the fit lands between two sizes, size up for comfort.
