Step 1: Measure Your Finger at Home

Before using our tool, you'll need to measure your finger using UK-specific measurements. Here's how to do it with just a string and a ruler:

What You Need

• String (or thin paper strip)
• Ruler
• Pen

Instructions

• Wrap the string around the base of your finger.
• Mark the point where the string overlaps.
• Lay the string flat and measure the length (in millimetres) from the start to the mark.
