Choosing Frames

Select Your Frames

The Forsight Vision optometry team has put together the following guidelines to help you select frames that flatter your face shape.

What’s Your Face Shape?

The best way to determine which frame shape is best for you is to figure out what face shape you have. At home, stand in front of a mirror (hair pulled back) and trace the outline of your face on the mirror with a bar of soap. Step away and view the shape with a critical eye. Whatever shape that outline most closely resembles will help you begin your frame selections.

In general, the shape of your eyeglass frames should be the opposite of your face shape. Faces with sharp angles look best with softer, rounded frames, while rectangle frames or those with sharp corners look great on those with rounder features.

Matching Frames to Face Shapes

FramesHere are examples of some of the most common face shapes, along with their most flattering frame designs:

Oval Face

An oval face is even overall, with high cheekbones and balanced proportions. Choose frames that follow your brow line and that measure at least as wide as the broadest part of your cheeks. Rectangular or diamond frames also look good on oval faces.

Round Face

Round faces are almost as wide as they are high, with very soft features and often hidden cheekbones. These faces cry out for some angles. Choose smaller frames with sharp edges, and avoid round or oval shaped eyeglasses.

Heart Shaped Face

A heart face also looks like a triangle with the point facing downward. Even out this extreme shape by choosing frames that look wider at the bottom than at the top. Rimless frames can give the same visual effect as actual bottom-heavy frame shapes. Actual triangular frames or aviator glasses do well with heart shaped faces, too.

Bottom Heavy Triangle

With the opposite of the heart shaped face, the forehead is narrow with a wide, distinctive jaw. Even out the face with glasses that are heavier on the top line, with decorative accents or darker frames along the brow line.

Square Face

The square face may seem short, much like the round face, but it features a prominent jaw and broad forehead. Frames that lengthen this shape and soften the harsh angles are soft ovals that are wider than they are tall.

Diamond Shape

The rarest of all face shapes, the diamond has a pointed chin, narrow forehead, and wide, prominent cheekbones. Choose softly curved oval frames to highlight dramatic cheekbones, or go for frames with heavy brow lines such as cats eye frames or wayfarer styles.

Square Oval Oblong Round Heart Triangle Diamond


A square face is often characterized by a strong jaw line, a broad forehead, and a wide chin and cheekbones. The width and length of the face are close to being equal. Frames should be selected to make the face look longer and to soften the square angles of the face. Choose frames that are slightly curved (like an oval shape) and that have more horizontal than vertical real estate.


The oval face is identifiable by its balanced proportions. The forehead is slightly wider than the chin and cheekbones are high. Frames should complement the natural proportions of the oval. Choose frames that are wide or wider than the broadest part of the face and that follow your brow line. Often, diamond or rectangular shapes work best for oval shapes.


Although fairly similar to an oval shape, an oblong face is longer than it is wide. The ideal frames will shorten the face by creating a break in the length of the face. Choose frames that have depth and a low bridge to shorten the nose. Try frames that are round, deep, have low-triangle shapes, or that have strong vertical lines.


A round or full face is characterized by having the same width and length. For round faces, frames that add length to the face often work best. Frames that lengthen the face are typically angular, narrow and are wider than they are deep. It is best to avoid round style frames as these will exaggerate the roundness and curves of the face.


A heart shaped face looks like a heart or a triangle with the point facing down. The forehead is very wide and cheekbones are high while the face narrows towards the chin. Counterbalance the narrow chin by choosing frames that are wider at the bottom. Generally, light colored and rimless frames work best, although aviator, butterfly and low-triangle styles also work well.


A base-down triangle face has a narrower forehead with full cheeks and a broad chin. To offset a broad chin, select frames that widen at the top. Great selections include frames that have heavy color accents and detail on the top part of the frames. Cat-eye shapes also work well to add width and emphasize the narrow upper part of the face.


A diamond shaped face is often characterized by high, dramatic cheekbones with a narrow eye line and jaw line. This shape is the rarest of all the shapes. Oval frames that are soft in style typically work best to highlight the eyes and cheekbones. Select frames that have detailing, distinctive brow lines, are rimless or a cat-eye shape for best results.
