Glasses by face shape: the complete fit guide
Finding the right frame starts with knowing your face shape. The right pair balances your features, complements your proportions, and feels effortless to wear. This guide breaks down the six main face shapes, the frame styles that work best for each, and how to measure your own at home.

How to measure your face shape at home
A quick five-step method using a mirror, a soft tape measure, and three reference points: forehead, cheekbones, and jawline.
Find your face shape →Round faces
Round faces have soft curves and similar width and length, so frames with angles and structure add definition. Rectangular, square, and geometric shapes work especially well, as do bolder browlines that draw the eye upward.
Oval faces
Oval faces are the most versatile and suit nearly every frame shape. The goal is to match the natural balance of your features without overwhelming them. Geometric and oversized styles tend to look especially flattering.
Shop frames for oval faces →Square faces
Square faces have a strong jaw and a broader forehead, so softer, curved frames help balance the angles. Round, oval, and cat-eye shapes are the most flattering, with rimless or thin frames adding lightness.
Shop frames for square faces →Heart faces
Heart-shaped faces are widest at the forehead and narrow at the chin. Frames that widen toward the bottom — like aviators, oval, or rimless rectangles — help balance the proportions naturally.
Oblong faces
Oblong faces are noticeably longer than they are wide. The best frames add width and visual interest at the eye line, making the face appear more balanced. Oversized and decorative frames work well.
Diamond & triangular faces
Diamond and triangular face shapes have prominent cheekbones with a narrower forehead and jawline. Frames that draw attention upward — cat-eye, browline, and oval shapes — soften the cheekbones and balance the upper face.
Asian fit & low bridge
Asian fit and low bridge frames are designed for faces with a lower nose bridge — a fit detail that standard frames often miss. The result is frames that sit properly without slipping, pinching, or leaving marks.
Fit by feature
Face shape is one part of fit. The rest matters too — face size, nose bridge, head width, even hairline. These guides cover frame choices for less commonly discussed fit considerations.
Frequently asked questions
Pull your hair back and look in a mirror, then trace the outline of your face. Most people fall into one of six categories: round, oval, square, heart, oblong, or diamond. Measuring your forehead, cheekbones, jawline, and face length gives you a precise answer in under a minute.
Wayfarer-style and rectangular frames in medium proportions tend to flatter the widest range of face shapes. They balance soft and angular features without overwhelming any one of them, which is why they remain a year-after-year bestseller across both prescription glasses and sunglasses.
Yes, the same fit principles apply. Sunglasses tend to be larger than optical frames, so the difference is more visible on your face. Choosing a shape that complements your features makes sunglasses feel intentional and well-fitted rather than borrowed or oversized.
Absolutely. Face shape guidelines are starting points, not rules. Some of the best eyewear choices intentionally play against face shape for a distinctive look. The right pair is the one that feels right to you. Face shape simply helps you understand why certain frames flatter more than others.
Start by browsing frames in the shapes recommended for your face, then narrow by colour, material, and size from there. If you're ready to start, the eyeglasses collection is a good place to browse by shape, style, and material.
