Ring Sizing

Getting the perfect ring fit is essential; otherwise, what’s the point? To get that perfect fit, you have to know your finger size. The ring should fit comfortably; not too tight, but loose enough to slip over your knuckles. Finger size also changes for several reasons:

For those reasons, you should measure your finger several times to get an accurate measurement. Materials that stretch, such as string and paper, are not reliable tools. Instead, Forever Diamonds offers a free ring sizer to help you find a perfect fit.

In the United States, ring sizes for men and women vary widely. Average ring sizes for women range from 3 to 9, with 6 being the most common. For men, the average tends to range from 8 to 14, with 9 being the most common.

If you want to buy a ring as a surprise, you can ask friends or family to see if they know the ring of whom you are buying it for. You can also borrow his or her ring and determine the size that way. Be aware that the ring has to be from the same finger – fingers vary in size as well.

Forever Diamonds offers free ring resizing on site.
