Do you ever forget your ring size no matter how many times you measure it?
Additionally, finger thickness changes over time and with age.
Even if you find a cute ring on an online shop and want to buy it, you can't make a purchase if you don't know which finger it is for and what size it is.
Here's a quick way to measure your ring size!
Plus, we'll also introduce you to a super convenient gadget that lets you easily measure your ring size in just 5 seconds!
①How to use paper you have at home

- Get a strip of paper and a pen.
- Wrap the paper around the widest part of the finger where you want to wear the ring.
- Mark with a pen where the paper goes around once.
- Use a ruler to measure the distance from the edge of the paper to the mark.
- Check your size on the ring size chart.

You can measure your ring size at home using items you have at home, but it takes a little time.
② Wrap a tape measure around your finger

- Wrap the tape measure around the widest part of the finger you want to wear the ring on
- Check the size of the overlapping part of the tape measure.
- Check your size on the ring size chart.
It's hard to measure with a tape measure...
I think most people have a tape measure at home, so it seems like a convenient solution, but to be honest, it's a little difficult to measure.
If you wrap the tape measure diagonally to see the numbers, there will be an error of several millimeters.
As you can see from the ring size chart above, a difference of just a few millimeters can change the size.
However, it is not recommended for those who want to measure accurately.
③Purchase a ring size gauge

This is definitely the recommended method!
Ring size gauges can be purchased at craft stores such as Tokyu Hands and Yuzawaya, or online at sites like Amazon, for around 1,000 to 5,000 yen.
The price range for ring size gauges varies because the price varies depending on the thickness of the ring size gauge (the width of the ring).
Even if a narrow ring and a wide ring are the same size, the wide ring will feel more constricting when worn.
So, if you measure your ring size with a narrow ring size gauge and then buy a wide ring with that size, you may find that it's tighter than you expected and you can't wear it for long!
It's expensive to buy all the ring gauges
Ideally, you would have a variety of ring size gauges in different widths, but doing so could end up costing you enough to buy an entire ring...
I was searching for a good item for people who want to know their ring size more easily, and I found it!!!
Lastly, we would like to introduce our special item.

First, let me show you how to measure.

This ring size measure is marked with Japanese standard ring sizes, so you can easily measure your ring size quickly.
It also has markings for Japanese sizes 1-30, so anyone can use it.
What's more, this ring size measure can be reused, so it's great for those times when you suddenly remember what size your finger is.
Precautions when using a ring sizer
One thing to note is that even if the ring size is the same, say 11, a wider ring design will feel more oppressive.
Therefore, when purchasing a wide ring, we recommend purchasing one to two sizes larger than the size measured with a size tape.
Find the right fit for your ring size tape, neither too tight nor too loose, and bend and straighten your finger while the tape is still wrapped around it to check how tight it is.
Please note that if the straps dig into your fingers too much when you bend and straighten them, they are too tight.
