How to Measure Ring Size at Home | Arneiro Guide
Learn how to measure your ring size using the Arneiro guide.
The guide allows you to find your ring size in two simple ways:
- Measure directly on your finger
- Measure an existing ring
We recommend confirming your size using both methods whenever possible.
Method 1: Measure Your Finger
Step by step
- Print the Size Guide on an A4 sheet at actual size
- Cut out the finger sizer indicated on the guide
- Make a cut along the marked line
- Insert the end of the sizer into the slit
- Place it around your finger
- Adjust until it feels comfortable and secure
- The number shown indicates your ring size
Tip: The sizer should pass over the widest part of your finger.
Method 2: Measure an Existing Ring
Step by step
- Choose a ring worn on the ring finger
- Place it over the circles on the guide
- Find the circle that matches perfectly
- Ensure the circle outline is visible inside the ring
- If the size falls between two options, choose the larger one
This is the most accurate method, ideal for surprise proposals.
