Gold Ring Resizing Conversion Chart

Ring Sizing & Conversion Chart

Find out your ring finger size using this handy jewellery guide and conversion chart. Determine the perfect fit for your next gold ring easily so you can shop with confidence, or organise a resize with our jeweller.

Vintage rings come in all sorts of sizes and sometimes the perfect design isn't the perfect fit. So find out ahead of time so you can have it resized prior to purchasing. That way when your ring arrives it is ready for wear. 

Use this helpful chart to convert the different international ring sizes, and compare them with mm & inch measurements.
