Ring Sizing Guide

Find Your Perfect Fit

At STORYMADE, we create jewellery made with meaning and that means ensuring it sits perfectly on your finger. Use our easy guide below to discover your ideal ring size.

✦ Option 1: Measure a Ring You Already Own

This is the easiest method if you are buying a gift or trying to keep a surprise!

  1. Select a ring that already fits the intended finger beautifully.

  2. Measure the inside diameter of the ring in millimetres (mm) using a ruler. Ensure you measure straight across the widest inside point, excluding the metal walls.

  3. Match your measurement to the handy conversion chart below.

✦ Option 2: Measure Your Finger

  1. Wrap a thin strip of paper or string snugly around the base of your finger.

  2. Mark the exact spot where the ends meet with a pen.

  3. Lay it flat and measure the length in millimetres (mm) to find your circumference.

  4. Match your measurement to the conversion chart below.

✦ Option 3: Professional Accuracy (Recommended)

Want 100% peace of mind before investing in your next piece? We have two foolproof options for you:

  • Grab a STORYMADE Sizer: You can purchase one of our handy, reusable plastic ring sizers right here on our store for a small fee. It works just like a mini belt and gives you an instant, accurate reading.

  • Visit a Local Jeweller: Pop into any high street jeweller. They will happily measure your finger using professional sizing rings free of charge.

💡 Tips for the Perfect Fit

  • Timing is Everything: Measure your fingers at the end of the day when they are at their largest.

  • Temperature Matters: Avoid measuring when your hands are cold, as fingers can shrink up to half a size.

  • The In Between Rule: If your measurement falls between two sizes, we always recommend choosing the larger size.

  • Band Width: Wider statement bands naturally feel a bit tighter. Consider sizing up half a size for rings with a thick band.

Don't stress about a loose fit! If you order a ring and it arrives feeling a little too loose or if your fingers shrink in the winter we offer discreet silicone inserts right here in our store. They slip invisibly onto the inside of your band to make it fit safely and perfectly.

Still unsure? We are always here to help you find the perfect fit. Get in touch with our team and we will gladly guide you. 💛
