If you’re shopping for glasses, you need to know your face shape so that you can buy glasses that compliment the natural shape of your face. As an example, I analyzed the shape of my face by taking a digital photo and tracing the outline of my face in a simple image-editing program (Microsoft Paint will work). You can also trace your face on a mirror with a dry-erase marker or lipstick. This is what I came up with. As you can tell, my face shape is a slightly oblong rectangle (almost a square).
Other common face shapes are square, round, oval, or triangle (“angular”). With my face shape, which features a chin of similar width to my cheeks, and a face that is longer than wide, it is important to minimize the length of my face by selecting a pair of eyeglasses that is wide enough to extend the entire width of my face.
Another good rule-of-thumb is that you should choose a frame shape that is the opposite of your face-shape or jawline. I have an almost squared jaw-line, so I should have slightly curved glasses. If you have a round face, you should look for a more squarish pair of glasses. If you are lucky enough to have a nice oval face, any eyewear will look good on you. Finally, if you have a very angular or triangle face, or a very pronounced jaw-line, rimless frames are an excellent choice.
My face, which has a somewhat pronounced jaw-line and is taller than wide, calls for a slightly rounded, fairly wide frame with a minimal rim. Your results may vary and you may not fit neatly into a given face shape, but take on aspects of several. If you’d like me to analyze your face shape and recommend a general frame-type, shoot me an e-mail and attach a picture. Make sure to include a descriptive subject line. Be warned, I’ll post my analysis and your picture for everyone to see. Resources: A glossary of face shapes.
