RING SIZE GUIDE

Finding your ring size should feel simple. Whether you’re treating yourself, choosing a gift, or investing in something meaningful, this guide walks you through the easiest ways to get the perfect fit - from home, in just a few minutes.

HOW TO MEASURE YOUR RING SIZE AT HOME

1. Use an adjustable ring sizer

The most reliable way to measure your ring size is with an adjustable ring sizer - the same style used in jewellers’ workshops.

HOW TO USE IT
  1. Slide the sizer onto your finger.
  2. Tighten until it feels snug but comfortable.
  3. Check the letter that aligns with the arrow - that’s your UK ring size.

Order our adjustable ring sizer for 50p, and ensure a perfect fit for any Maya Magal ring.

2. Measure a ring you already own

If you have a ring that fits the same finger, use our Printable Ring Size Guide.

HOW TO USE IT

  1. Download and print the guide at 100% scale.
  2. Place your ring on the circles until the inside edge matches one perfectly.
  3. Use the corresponding letter size.

This method is quick, easy, and reliable - especially for engagement and signet rings.

3. Use the string or paper method

A simple method if you don’t have a ring nearby.

You'll need:

  • A thin strip of paper or string
  • A pen
  • A ruler

HOW TO MEASURE

  1. Wrap the string or paper around the base of your finger.
  2. Mark where the ends meet.
  3. Measure the length in millimetres.
  4. Compare the measurement with our UK ring size chart.

This method is a helpful starting point, though less precise than using a ring sizer.

TIPS FOR ACCURATE RING SIZING

  • A ring should fit snugly enough that it won't slip off, but loose enough to slide comfortably over your knuckle.
  • Finger size can vary throughout the day due to temperature, hydration and activity levels. For the most accurate measurement, size your finger when it feels normal and comfortable.
  • Your dominant hand is often slightly larger than your non-dominant hand. Measure the finger you'll be wearing the ring on.
  • If you're purchasing a surprise gift, borrowing a ring that is already worn on the same finger can help provide a useful size guide.
  • Rings with stones that sit across the full width of the band may fit more snugly than a simple band and can benefit from a slightly larger size.
  • Wide bands and chunky ring styles can fit more snugly than delicate bands. If you're choosing a signet ring or a wider design, you may prefer to size up slightly for a more comfortable fit.
