For some, choosing a frame that fits can be very difficult and time consuming. This guide will explain what to look for when choosing a frame to fit your face. Frames come in all different shapes and sizes and it is important to get the most suitable ones for your face. The size of your frames can have an impact on the way your glasses look on your face and how comfortable they are.

  • The top rim of the glasses should be straight and no higher than the line of your eye brows

 

  •  The bottom rim of your glasses should not rest on your cheeks, even when smiling as this can cause them to irritate your skin and become uncomfortable

Frame size

The frame size is listed on the inside of the arm or the bridge of the frame.

There are three numbers to look out for when looking at the frame size: Lens width, bridge width and total length of the arm.

The size will be shown as three numbers which may look like: 54 □ 18 140

  • The 54 represents the measurement of the lens diameter.
  • The 18 represents the measurement of the width of the bridge, also known as distance between lenses (DBL).
  • The 140 represents the total length of the arm from the dowel point (screw) to the very tip of the arm.

All of the above measurements are measured in mm.

Do you have existing glasses that are comfortable?

If you currently have a frame that is a comfortable fit, it is a good idea to take a note of the measurements for that frame (Using the frame measurement guide above).

Measure yourself to find the most suitable size for your face

It is possible for you to measure your own face to determine your frame size; this can be done by using the simple steps shown below:

  • Position yourself in front of a mirror and hold a ruler up so that it is lined up with both of your temples (see picture below)

  • Measure the distance in millimetres between your left and right temples.
  • When choosing a frame for the recorded measurement, you will need to work out the total width of the frame. This is done using the following formula: Lens diameter x2 added to the bridge width.

For example: Lens diameter of 55mm and bridge width of 18mm.

55 x 2 = 110mm

110 + 18 = 128mm

When choosing a frame, the measurement of the width of your face may be out by 1-2mm. This will not make any difference especially when choosing an adjustable bridge pad frame or high-wrap sunglasses.

You will find a wide selection of frames in all shapes and sizes, colours and materials so with the help of the above guide; there should be no stopping you!
