How to measure your ring: Choosing the right ring size

If the ring size is even slightly wrong, it can be difficult to put on and take off and can put pressure on your finger.

Here, we will explain in detail how to easily measure a ring at home, and introduce some points to consider when choosing a ring size.

1. Ring Measurement Basics

Why is size measurement important?

If your ring is not the correct size, these problems can occur:

Fit: If the size is not right, your fingers may hurt or fall off easily.
Appearance of the design: This can also lead to issues such as the ring being easy or difficult to rotate.
Risk avoidance: If the size is too small, it can cause blood circulation problems, and if the size is too large, it can increase the risk of getting lost.

2. How to measure a ring STEP by STEP

STEP 1: Decide which finger to measure

Measure the thickest part of the finger you want to wear the ring on (around the second joint) .

*Since the thickness of your fingers can easily change depending on the temperature and time of day, it is recommended that you measure your fingers in the evening or when they are stable and not swollen.

STEP 2: Wrap the string or paper tape around the

Wrap a thin string (a ribbon is fine) around your finger and make it fit snugly.
The key to getting close to the feeling of actually wearing a ring is to make it neither too tight nor too loose.

STEP 3: Measure the length

Mark where the strings join with a pen or something similar, stretch them out straight and measure them with a ruler. Check the length (mm) in the size chart below.

Point: It may be easier to measure a thin and flexible string than paper. Repeat several times and calculate the average for more accurate results.

4. Frequently Asked Questions and Points to Note

When is the best time to measure?

There is usually less swelling in the morning and more swelling in the evening. If you measure during the stable period from midday to evening, you will get a size that is closer to what you can actually use.

What difference does the width of the ring make?

Wider rings tend to feel tight even if they are the same size, so in some cases it may be better to choose a slightly larger ring for a better fit.

What changes with the seasons?

Your fingers are likely to swell in the summer or after exercise. If you are unsure about the size, one option is to consider an adjuster type or a size with a little extra room.
