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:
If you need help finding the right size, try our Size Advisor:
The size of the frame counts as functional information, which is defined by one principal number:
This information defines the following sizes:
| Hinge to hinge (in) | Hinge to hinge (mm) | Size |
|---|---|---|
| <4.8 | <121 | XXS |
| 4.8-4.9 | 121-124 | XS |
| 4.9-5 | 125-128 | S |
| 5.1-5.2 | 129-132 | M |
| 5.3-5.4 | 133-136 | L |
| 5.4-5.5 | 137-140 | XL |
| >5.5 | >>140 | XXL |
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.
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.
Fitting is aesthethical information which determines the amount of face coverage for a given size.

Since 1913, Prada has been synonymous with cutting-edge style. Its intellectual universe combines concept, structure and image through codes that go beyond trends. Its fashion transcends products, translating conceptuality into a universe that has become a benchmark to those who dare to challenge conventions focusing on experimentation.
Frame size is usually defined by lens width, bridge width and temple length. These values are always displayed in that order, in millimeters.

As a reference, you may want to check the size of your current eyewear, by looking at the inner side of the temple. Should you see a fourth number at the end, this refers to lens height (i.e. 49/19/140/45.9).
