Ring Size Guide
HOW TO MEASURE RING SIZE
A ring size is equal to the circumference of your finger. At Fujimori Kajita, our ring size is based on Japanese size. But fret not, the following ring size reference will show you a comparative scale of ring sizes from different countries. It will help you to easily convert American sizes or UK sizes to Japanese sizes. Our store provides free (one-time) ring re-sizing after purchase. For more info, please refer to our Maintenance page.
If you don't know what is your ring size, the following methods may help you.
METHOD 1: MEASURE A RING DIAMETER
If you have a ring you are wearing and you want to buy another one of the same size, you can simply measure its diameter with a ruler. The simplest way to do so is to place a ring on a piece of paper, circle it inside and measure the diameter (two opposite points through the center of the circle). When you obtain the length of the inner diameter, multiply it by the Pi number (3,14) and you will get the circumference.
When using this method, you should keep in mind that rings with a wide shank sit more tightly on a finger than thin ones. Therefore, their circumference should be slightly larger than that of their skinny counterparts. When you buy thin rings with a shank of up to 3 mm, there is no need to size up.
METHOD 2: USING THREAD, MEASURING TAPE OR STRIP OF PAPER
If you do not have a ring to measure, you may try this method. Take a thread or a strip of paper, wrap it around your finger, and cut off the ends or mark them with a pen. Then, measure the piece you’ve got with a ruler.
This method has a high chance of error since any ring, unlike a thread or strip of paper, has a certain thickness. Rings of paper, thread, and metal are completely different things. A thread may get too deep into the skin while paper vice versa might be too loose. A thin and narrow piece of paper rather than a thread is recommended. When you cut it to fit your finger, tape the ends together and make a paper ring. Then, try to put it on your finger so that it doesn’t get stuck on the joints between the phalanges. If you feel that such a makeshift ring hardly slights through your joints, you need to pick a ring one size larger.
Although this method is simple, it is not 100% accurate. To minimise the percentage of error, doing it multiple times (around 5 times) and taking the mean value is recommended.
