      Size and fit guide

      Choosing the right eyewear can be a complex process. This guide will help you find your best match. All eyewear has different functional and aesthetic characteristics, so we use three pieces of information to determine the following:

      What is frame size?

      If you need help finding the right size, try our Size Advisor:

      Find my size

      The size of the frame counts as functional information, which is defined by one principal number:

      • Hinge-to-hinge distance: the width of the frame measured from the inside of the eyewear starting from the center of each hinge.

      This information defines the following sizes:

      Hinge to hinge (in)Hinge to hinge (mm)Size
      <4.8<121XXS
      4.8-4.9121-124XS
      4.9-5125-128S
      5.1-5.2129-132M
      5.3-5.4133-136L
      5.4-5.5137-140XL
      >5.5>>140XXL

      How do I know the right size for me?

      Try our Size Advisor and we'll measure it for you! Or, you can use a ruler to measure the hinge-to-hinge distance of a pair of glasses that you already own.

      Other measurements

      If you already own a pair of glasses, you’ll find numbers engraved on the inside of the eyewear temple. These numbers indicate the following:

      The first number is the model name, followed by the lens width and bridge width. There is usually a third number that represents the temple length, or the measurement of the "arms" of your frame. Sometimes there is a fourth number that indicates the lens height.
      Each of these numbers is measured in mm.

      What is the fit?

      Fitting is aesthethical information which determines the amount of face coverage for a given size.

      The frames shown in the image are all the same size but each one has a different fit.

      The three possible fittings are:

      • Narrow: a small lens front for those who prefer to cover a smaller portion of the face.
      • Regular: a medium lens front designed for those who prefer to cover an average portion of the face.
      • Oversized: a larger lens front designed for those who prefer to cover a greater portion of the face.

      What are the bridge and nosepads?

      The four bridge and nosepads options are:

      • High bridge fit: offers a more secure and comfortable fit for those with a high nose bridge and lower cheekbones. A good choice if the bridge of your nose is above the level of your pupils.
      • Low bridge fit: offers a more secure and comfortable fit for those with a low nose bridge and higher cheekbones. A good choice if eyewear tends to slide down your nose, sit too low, or press on your temples or cheeks.
      • Universal fit: this option accommodates most face shapes.
      • Adjustable nosepads: nosepads that can be widened or narrowed to fit your unique nose shape.
