🔧 What it does & how to use

This tool lets you work out an accurate ring size at home before ordering a ring online, or use it in a jewellery workshop to check a customer's size. It's simple enough for a first-time buyer and handy enough for regular use behind the counter.

• Position it: slide the sizer around the base of the finger the ring will be worn on.
• Adjust the fit: move the tool until it sits snugly without pinching or sliding off.
• Read the size: note the US number (1-15) shown at the marker.
• Cross-check in millimetres: use the mm gauge alongside the US number if you need to convert to another sizing system.
• Re-check timing: measure a couple of times, ideally when your hands are at normal temperature, as fingers can swell or shrink through the day.
