Ring Size Guide: How to Measure Your Ring Size
Welcome to our complete ring size guide. Choosing the correct ring size is essential to ensure comfort, longevity, and peace of mind. Whether you’re buying an engagement ring, a wedding band, or a gift, learning how to measure your ring size at home can save time, avoid costly resizing, and ensure the perfect fit.
This detailed ring size guide will help you accurately measure ring size, understand international sizing conversions (UK, US, EU), and provide expert advice to make your purchase stress-free.
Why Accurate Ring Sizing Matters
Getting your ring size right is crucial. An incorrectly sized ring may feel uncomfortable, fall off, or be too tight to wear comfortably. Measuring your ring size correctly from the start avoids disappointment, resizing costs, or even damaging the ring during alterations. Our ring sizing guide helps you get it right the first time.
How to Measure Your Ring Size at Home
You don’t need to visit a jeweller to measure your ring size. Here are 3 simple ways you can do it at home:
1. Use a Ring Sizer
One of the most accurate methods is using a plastic or metal ring sizing tool. This allows you to test multiple sizes and find the ideal fit quickly. Many online jewellery stores offer affordable ring sizers you can order to use at home.
2. Measure an Existing Ring
If you already have a ring that fits well, measure its inside diameter using a ruler or caliper. Match that measurement to a sizing chart to determine your exact ring size.
3. Use String or Paper
Wrap a strip of paper or string around your finger, mark where it overlaps, and measure the length with a ruler. Compare the measurement to a ring size chart to find your size.

Ring Sizing Tips for Accuracy
- Measure your finger at the end of the day for the most accurate size.
- Ensure your hands are warm, as cold fingers shrink slightly.
- If you’re between sizes, always round up for comfort.
- Wider rings may require a slightly larger size than thinner bands.
