What is the best way to guess your ring size? ›

Ordering a plastic or metal ring sizer is a relatively affordable and simple way to guess ring size. Just measure your partner's finger with the rings on the tool, and the ring that fits best will roughly correspond to the size of ring you should buy.

Average Woman's Ring Size

You can see that approximately half of women's ring sizes were between 6 and 8 with 7 being the most popular size. Whole sizes are more popular than half sizes and rings range from a tiny size 3 up to size 11.5.

Going up or down by half a size means a difference of roughly 1 millimeter. Although this may seem negligible, with a snug fit, a 1 millimeter variance can significantly impact comfort. For wide bands 2-3 millimeters thick, that extra millimeter's difference is amplified.

Using a measuring tape is considered to be the best and most accurate method to determine your ring size. Give yourself enough space to accommodate your knuckles for the best results. Also, you should measure the finger where you plan to wear the ring, since the finger size on your left and right hands may differ.

An average finger size is 6 for women and 8 or 8½ for men. Finally, if your partner is above average height or build, their weight will be naturally distributed across their whole body, so it might be a good idea to start at around a ring size 7 for a woman and a size 10 for men.

The Gemological Institute of America (GIA) has declared that the average ring size for women is 6. However, you cannot trust averages if you want the best. The most common ring size woman is, at best, an excellent comparative reference and a sweet piece of trivia.

The most common sizes are 6, 7, 8, and 9, though women may wear sizes lower than 6, while men's rings tend to run in larger sizes of 8 to 14. While it would seem that your ring size would be similar to your shoe size in that it stays the same over time, this is actually not true.

Is a size 8 ring large for a woman? ›

In general, a ring size 8 is considered slightly above average for a woman. Ring sizes can vary significantly based on factors such as geographical location, body type, and personal preference.

Or you may ask, “How loose can I wear it?” because you'd like it to be comfortable. For this, I'd like to share a quick video and my own rule of thumb. Rule of Thumb: A proper fitting ring should slide over your knuckle with a little friction and fit snugly on your finger, but not too tight.

Over time most people's finger will adjust to a tight ring, and you'll often see an indentation at the wearing position. As we age, fingers and/or knuckles usually get bigger.

Should you go larger or smaller? If you're between ring sizes or there's a reasonable difference in your size throughout the day, a good thing to bear in mind is that it's always better to go for a slightly larger size than one that's too small, so you should err in that direction.

An average finger size is 6 for women and 8 or 8½ for men. Finally, if your partner is above average height or build, their weight will be naturally distributed across their whole body, so it might be a good idea to start at around a ring size 7 for a woman and a size 10 for men.

If you are looking at a ring that is extra wide, 7mm or wider, you should order your band at least a 1/4 size larger than the size of your actual finger size. If in doubt, choose the smaller size. Remember, more sizing mistakes are made by ordering rings too large rather than too small.
