Oval
This face shape is known for being well proportioned, balanced, and relatively easy to fit. Most styles look good on this face shape. Depending on each individuals colouring (hair, complexion, and eyes), practically any colour frame will suite this shape.

Oblong
This face is longer than the forehead and chin proportionally speaking. It is suggested to use a full rim frame with horizontal lines to balance things. Also, consider dark colours with round or oval shapes. This may reduce the apparent distance from forehead to chin.

Round
The length and the width of this face are equal. Similar to the oval face, the round face can be accentuated or de-emphasized. To de-emphasize, consider angles with a horizontal look to lengthen the face. Also try to use light coloured or rimless frames with darker temples. To highlight the round face, use round frames. Avoid completely dark frames.

Square
The most obvious feature is a square or wide jaw. Try to increase the length of this face with round or angled frames that are slightly heavier colours.

Diamond
This face has particularly wide cheekbones. The chin and forehead tend to be narrower and thus need to be emphasized. Try using a round frame, which is heavier at the top, and avoiding anything below the cheekbones. A rimless design often will suit this face.

Triangle (Pear)
This face has a wider jaw than forehead. This shape suites dark frames preferably round or angled. Acetate collections can help to de-emphasize wider jaw while volumizing the upper facial area.

Triangle (Heart)
Contrary to the “pear” triangle, the “heart” triangle has a wider forehead than jaw. Your aim is to draw attention away from the forehead and volumizing the chin. Try using small frames that don’t stand out too much. Rimless and light coloured frames suit this face the best.

The Face Shape Theory
Have you ever wondered what frame suites your face the best? Or why certain frames look better on others? Check out this theory.

It has been proposed that every person has a face that fits into the face shape theory. The following are the basics shapes included in this theory. Identifying your face shape can be a critical first step in selecting the right frame.
