Ring Size Guide

Finding the perfect fit for your ring is essential for comfort and style. If you're unsure about your ring size, our guide will help you measure it accurately.     

Ring Size Chart

Rosabrillo uses the European ring size chart that is based on the inner circumference of the ring in millimeters. Unlike some other sizing systems that use numbers arbitrarily assigned to sizes, the European system directly corresponds to the measurement of the finger's circumference. 

Rosabrillo Size Circumference (mm) Diameter (mm)
48 48 mm 15,29 mm
50 50 mm 15,92 mm
52 52 mm 16,56 mm
54 54 mm 17,20 mm
56 56 mm 17,83 mm
58 58 mm 18,47 mm
60 60 mm 19,11 mm

 

Try one of three easy methods down below to make sure your ring fits perfectly, every time.

Method A - Measure an Existing Ring with a Ruler

This method works best if you already have the ring that fits the finger you want to determine the size. You will need the ring and the ruler.

  1. Select a Ring you already have - choose the ring that fits the finger you want to determine the size
  2. Use a Ruler - find a ruler that shows millimeters (mm), as this is the most common unit of measurement for ring sizing.
  3. Measure the Internal Diameter - place the ring on a flat surface. Measure the ring's inside diameter from edge to edge at the widest point. Make sure to measure the internal space only without including the metal edge of the ring in your measurement.
  4. Record the Measurement - note the measurement in millimeters. This is the internal diameter of your ring.
  5. Find Your Size - compare your measurement with our Ring Size Chart above and match it to the closest size. For example, if your measurement is 19 mm in diameter, your ring size is 60.

 

Method B - Measure Your Ring Size with a Piece of Paper

For this method, you will need a ruler, pen, scissors and a piece of paper.

  1. Get a Piece of Paper - cut a thin strip of paper - about 20 mm long and 8 mm wide
  2. Wrap It Around Your Finger - wrap the paper around the finger's base where you'll wear the ring. Make sure it's snug but not too tight.
  3. Mark the Spot -use a pen to mark the point where the end meets the rest of the paper.
  4. Measure the Length - lay the paper flat and use a ruler to measure the distance to the mark in millimeters (mm).
  5. Find Your Size - compare your measurement with our Ring Size Chart above. Each number corresponds to the EU ring size. For example, if your measurement is 52 mm in circumference, your ring size is 52.

Tips for Accurate Measurement

  1. Try Multiple Times - measure your finger several times, as size can change with temperature. Fingers might be slimmer when cold and swell when warm.
  2. Measure your finger at the end of the day when it's likely to be at its largest.
  3. Correct Finger - rings might fit differently on each hand, so measure the specific finger where you'll wear the ring for the best fit.
  4. Knuckle Size - if you have a large knuckle, it is necessary to measure the finger with a tightly pulled strip right in this area. If you have noticeably wider knuckles compared to the rest of your finger, the ring will always be slightly loose.
  5. For really thin bands or bands with a heavy stone, you can go a size down. For wide and thick eternity bands/rings you can go a size up.
  6. If you're between sizes, opt for the larger size for a comfortable fit.
