Last Update:

Take the guesswork out of finding the right fit. Every OLIVIO & CO frame is sized by age, so start with your child's age and use the measurements to confirm.

How to measure face width

  1. Have your child look straight ahead with a relaxed face.
  2. Hold a ruler or soft tape measure horizontally across the eyes.
  3. Measure from one temple to the other (the flat spots just outside the eyes, in front of the ears).
  4. Compare the number in millimeters with the "Fits face width" range for each size.

No ruler handy? Measure the front of a pair of glasses that already fits well, from hinge to hinge.

Reading the frame size

Frame sizes are written like 48□20-139: a 48 mm lens width, a 20 mm bridge (the gap between the lenses over the nose) and 139 mm temple arms. Every product page lists these under "Size & specs."
