Using what you have at home
Easy way to measure size

Method 1: Sticky Note

1. Things to prepare - Thin & Long paper (or a thick string), ruler, pen, tape. A long and thin sticky note will be the most recommended.
2. Wrap the paper around the thickest part of the finger you want to measure - The thickest part depends on the shape of your finger.
- Fixing it with tape makes it easier to measure.
- Wrap it around your finger and ensure it is fit
3. Mark the overlapping parts with a pen - It is more accurate to mark with a thin pen at the same time making sure that the paper fits your finger at the right tightness.
4. Measure the length between the marks - And compare it with the "finger circumference" on the ring size table. In this case given in the image measured as around 5.2~cm, could just round up to 5.3cm or 5.25cm.

Method 2: Ring’s Diameter

1. Things to prepare - Only two of them! Simple! Just a ring that you wear daily or any rings you already have with you and a regular ruler will do.
2. Measure the diameter - Take a ruler and measure straight across the inside of the ring from edge to edge. And compare it with the "inside diameter" on the ring size table.
