Face Shape Guide: How to find the perfect shape prescription glasses for your face shape

On the prowl for some new prescription eyewear but aren’t sure which styles suit your face shape best? Are you having trouble determining what shape your face is?

At Salt City Optics we understand that great prescription glasses and prescription sunglasses are as much about performance as they are about style and personality. We want you to feel good about how you look and believe that it starts with finding the right glasses for your face shape. That is why we have designed this guide to help you narrow down which frame styles will work best with your unique facial features.


4 Key Face Shapes 

While every face is a bit different, all face shapes fit comfortably into one of four categories: oval, round, square, and heart. 

Oval faces tend to be the most proportionately balanced. Oval faces tend to have narrow foreheads and chins (approximately equal in width) as well as high cheekbones. Because of the symmetry of this shape, almost all glasses flatter oval faces.

Opt for frames that match your face’s width, or go slightly wider. Bold shapes such as cat eyes and clubmasters look just as great as more reserved rectangle or square frame shapes. Avoid ultra-oversized frames so as to not throw off the natural proportions of your face shape.


Square faces are known for prominent jawlines and strong angular features. Your face is approximately the same width from your forehead down to your jawline. Because of your angular facial features, you’ll want to select glasses that have soft curves to balance your look.

Opt for rounded or swept frames that are wider than tall and stick to neutral or light colors. This will help lengthen and soften your angles.


Round faces are most recognizable for their lack of strong angles and their full cheeks. A round face’s forehead is about the same width as the jawline, and the chin is rounded and minimalized. With that said, you’ll want to opt for frames that contrast your face’s natural curves in order to make your face appear slimmer and longer.

Opt for frames that are wider than they are tall. Rectangular glasses will suit your face shape well, as will glasses with strong brow detailing. A narrower and adjustable bridge is ideal to keep your glasses from resting on your full cheeks.


Heart faces have a wider forehead than jawline with high cheekbones and a narrow, pointed chin. Some refer to this face shape as an upside-down triangle as well. The goal in selecting your eyewear is to minimize the width of your forehead while broadening the appearance of your chin.

Opt for frames that have prominent temple details and sweeping lines such as cat eye shapes or clubmasters. Frame width should be wider than your forehead as they will help slim and balance your face shape.


Find Your Face Shape

If you need a little extra help pinpointing your face shape, no worries! It’s time to measure your mug to determine your face shape and put you one step closer to finding your perfect pair of prescription eyewear.


Step 1: Grab a pen, paper, and tape measure or flexible ruler.
Step 2: Try to keep a straight face as you measure your forehead at its widest point, jawline at its widest point, and the length of the center of your face from your hairline to the bottom of your chin. Make sure to jot down these measurements, as we’ll need them for the next step.
Step 3: Let’s apply those measurements to determine your face shape.


Oval: Your face is about the same width at the forehead and jawline (within half an inch), but your face is at least one inch taller than it is at its widest point. Your jawline is soft, but does come to a rounded point at your chin. 

Heart: Your face is more than half an inch wider at the forehead than at the jawline, and your face is at least one inch taller than your forehead’s width. Your jawline is angular, tapering to the point of your chin.

Square: Your face is about the same width at the forehead as it is the jawline (within half an inch), and your face is less than an inch taller than it is wide. Your jawline is very squared and angular, and your chin comes to a distinct point.

Round: Your face is about the same width at the forehead as it is the jawline (within half an inch), and your face is less than an inch taller than it is wide. Your jawline is very rounded and soft, lacking angular definition and likely with a less prominent chin point.
