Ring size guide for men

Although there is no difference between men's and women's ring sizes, men's rings are typically larger, as men generally have larger fingers, according to e-Weddingbands. Men's rings also come in different styles than traditional women's rings. Since a ring's style can affect its fit and feel, it's important to consider both style and size when choosing a ring, according to the website.

Basic Size

Basic ring size in the United States ranges from size 3 (44.1 mm in diameter) to size 16 (77.4 mm in diameter), according to Just Men's Rings. The measurement is taken around the outside of the thickest part of the finger (other than the knuckle). The measurement around the base of a man's finger is the same as the measurement of the inside of a ring that fits that finger.

Sizing Methods

Jewellers use one of two methods to determine ring size, according to the Walker Metalsmiths website. In both cases the ring is slid down a marked, tapered sizing stick. The stick, sometimes called a sizing mandrel, corresponds to ring size. The mark corresponding to the point where the ring can't slide down the mandrel any farther is the ring size. In the true diameter method, this mark is where the wider side of the taper meets the edge of the ring. In the centre line method, the line in the centre of the ring is considered the ring size. The true diameter method works better for wider men's rings, according to the website.


The ring should fit comfortably on the finger, according to e-Weddingbands. If the finger bulges from the sides of a ring when the hand is relaxed, the ring is too small. The ring also should slide on easily. There should be some resistance removing the ring and it may be difficult to slide the ring over the knuckle, but this does not necessarily affect the ring's fit, especially for men, who typically have larger knuckles.


The wider a ring is, the tighter it will fit, according to e-Weddingbands. Many men's rings are available in a comfort-fit style, where the sides are slightly domed. Domed rings slide more easily over large knuckles, according to the website.


Finger size varies throughout the day, according to e-Weddingbands. Temperature and activity also affect finger size. Cold fingers are smaller than warm fingers, and fingers are usually larger in the morning than at night, according to the website. The best time to measure a finger for ring size is at the end of the day.
