Don't know your face shape?

Don’t stress. Here are a few tips to help you figure it out. While all faces are unique, most tend to fall within one of the following categories.


If you have an oval face, you’re in luck and can probably pull off any frame! Oval faces are versatile, balanced and gracefully taper towards the chin with a gently curving jawline. Your face is likely longer than it is wide and you probably have a wider forehead and prominent cheekbones.

TIP: Most glasses will fit you well since your symmetrical face shape acts as a blank canvas. You can have fun with round, rectangular, or square shape frames. Plus, you can even play around with oversized frames (think: Jemison). You might want to avoid glasses with smaller and narrower widths.

TRY: Turing, Roebling, Nash, Carver, Kepler, Hopper, Faraday, or Jemison.

Square faces are characterized by relatively straight sides, angled jawlines, and minimal curves. The forehead, cheekbones and jawline are essentially the same width, and the vertical to horizontal proportion of your face is nearly one to one.

TIP: Try frames with softer curves or semi-rimless styles to contrast your angled features. Thinner frames help balance your look. You might want to stay away from sharp square or rectangular frames to avoid appearing boxy. If you’re looking for a rectangular shaped frame, try one with rounded edges.

TRY: Turing, Roebling or Kepler.

Highlighted by their curves, round faces often feature prominent round cheeks and soft jaw angles. The face length and width are usually proportional—similar to square faces! This shape is often widest at the cheeks and features fullness below the cheekbones.

TIP: Find glasses that add angles and sharpness such as thinner square or rectangular frames. Adding lines help to contour your face and to highlight your cheekbones. Try and stay away from overly rounded glasses.

TRY: Nash, Carver, Hopper, Faraday, or Jemison.

If your structure is similar to an oval shape—but a touch longer and maybe not quite as wide—then you probably have an oblong face. Oblong faces are long, slim and gracefully taper toward a narrow chin.

TIP: Much like oval faces, oblong faces can essentially rock any frame. Find glasses that highlight your shape and try adding angles with square or rectangular frames.

TRY: Turing, Roebling, Nash, Carver, Kepler, Hopper, Faraday, or Jemison.

If your forehead is the widest part of your face and narrows down to a pointed chin, chances are you have a heart shape face.

TIP: Show off those high cheekbones with thinner temple frames that are slightly wider than your forehead. You can try square, rectangular, or round glasses, but try and avoid frames with a heavy brow line.

TRY: Turing, Roebling, Carver, Kepler, Hopper, Faraday, or Jemison.

Understanding the numbers

Frame dimensions Frame dimensions mobile

You can locate the following measurements—lens width, bridge width, and temple length—on each frame’s left arm. Please note everything is listed in millimeters.

Lens width

The lens width is a horizontal measurement and gives you a sense of how large the frames will be. This will help you pick a frame that isn’t too wide or too narrow for your face. You’ll want your eyes to align with the center of the frame.

Lens width Lens width mobile

Bridge width

The bridge width is measured horizontally at the top of the frame. It’s the distance between the two lenses. Select a style where the bridge of the frame contours to the shape of your nose with as little gapping as possible.

Bridge width Bridge width mobile

Temple length

The temple length measures the arm of the frame. It starts with the hinges and goes all the way back behind your ear.

Temple length Temple length mobile

Bridge fit

High bridge

If you’re looking for a high bridge fit (your nose sits higher on your face) try glasses with a nose bridge closer to the top of the frame or with a keyhole. Our Nash style is a great option for high bridge noses.

Low bridge

If you’re looking for a low bridge fit (when the bridge of your nose starts level with or below your pupils) the Kepler is a great option! Our Kepler frame features adjustable nose pads, to comfortably accommodate your unique fit.

Keep in mind that while bridge fit is important, also make sure you select a frame based on your face size and width!

Other helpful tips

Tip #1

When selecting frames, pick glasses that compliment your hair color, eye color, and personal style.

Tip #2

Make sure to coordinate your frame size with your face width (if you have a smaller face, try one of our smaller frames).

Tip #3

As a rule of thumb, frames opposite your face shape tend to highlight your features best.

Tip #4

Don't let your eyebrows (no matter how thick or thin) hide below or make contact with the frame.

Tip #5

You don’t want to let the edge of the frame rest on those lovely cheek bones of yours.

Tip #6

Follow these guidelines for both eyeglasses and sunglasses, but note for sunwear you can go for a more oversized style.
