A typical triangular face has a broad forehead - the width of the face tapering down to a narrow, rounded chin. The best frames minimise the width of the face's top and bring the overall look back into balance. Frames that are wider at the bottom will help to achieve this, placing greater emphasis on the lower half of the face. Very light colours, light materials and rimless frame styles can also help, so consider small square or rounded frames to achieve more balanced proportions for the whole face.
