Picking out the perfect pair of eyewear or sunglasses can be difficult, because how do you know if it will fit your head? First step is to determine your head size. If you know the circumference (the measurement around your head), it will be much easier to know if the eyewear will fit you. Simply, take out a tape measure and measure the circumference of your head. Compare the number you get with the table you see above. 

For instance, if your head has a circumference of 58 cm you have a large head size, and your face should be able to fit all our models that covers this head size. Many of our models have more than one fitting head size, for instance M-L. 
This means that if your head size is either medium or large, you will be able to fit this model.
