The Ultimate Guide to Choosing Glasses for Your Face Shape

Choosing the right glasses is not just about picking a shape you like. The most flattering frames work in dialogue with your facial features, softening angles, adding definition, or simply sitting in natural harmony with your proportions.

This guide walks you through the main face shapes and the frame styles that tend to work best for each, along with a few practical rules to check fit once you try them on.

How to find your face shape

Stand in front of a mirror in good light and compare the width of your forehead, cheekbones and jaw. Then consider the overall length of your face.

The widest part of your face and the shape of your jaw are usually the two most telling indicators. Most people fall into one of six main categories: oval, round, square, heart, diamond or oblong.

Glasses for an oval face

An oval face is often considered the most versatile shape, balanced proportions mean almost any frame works well. Your main focus should be avoiding extremes: frames that are too narrow can look pinched, and oversized styles can overwhelm.

Look for frames that maintain the natural balance of your features without adding too much width or height.

Try: wayfarer, rectangular, aviator, cat-eye, round.

Jimmy Fairly pick: The Emmy, a soft oval with slim proportions that suits a wide range of face shapes without effort. Clean, versatile, and easy to wear every day.

Glasses for a round face

If your face is roughly as wide as it is long, with soft, curved features, the goal is to add structure and elongate. Angular shapes create contrast and definition where roundness already does most of the work.

Avoid very round or very small frames, which tend to amplify the roundness rather than balance it.

Try: rectangular, square, geometric, browline.

Jimmy Fairly pick: The Elvie, a clean rectangular silhouette with precise proportions that adds definition without being severe. A strong choice for rounder features.

Glasses for a square face

A square face has a strong jaw and roughly equal width across the forehead, cheekbones and jaw. Soft, curved frames work best here, as they balance the angles rather than reinforcing them.

Oval and round shapes are the most flattering. Avoid very angular or geometric frames, which can make a square face appear more rigid.

Try: oval, round, butterfly, soft cat-eye.

Jimmy Fairly pick: The Napoli, a universally flattering silhouette built on balanced proportions. Neither too bold nor too subtle, it softens angular features without losing presence.

Glasses for a heart-shaped face

A heart-shaped face is typically wider at the forehead and cheekbones and narrows toward the chin. The goal is to balance the upper and lower halves of the face.

Choose frames that are slightly wider at the bottom, or that have a lighter, more open feel at the top. Avoid heavy browlines or top-heavy silhouettes that draw too much attention upward.

Try: aviator, round, oval, subtle cat-eye.

Jimmy Fairly pick: The Kos, a well-balanced silhouette that sits close to the face without overwhelming smaller or more delicate features. Its even proportions help harmonise a wider forehead with a narrower jaw.

Glasses for a diamond face

Diamond faces have prominent, wide cheekbones with a narrower forehead and jaw. Frames that add width at the forehead and sit lightly on the cheekbones tend to be the most flattering.

Cat-eye and oval shapes often work especially well, as they draw the eye upward and outward across the top of the frame.

Try: cat-eye, oval, browline.

Jimmy Fairly pick: The Sigi, classic proportions with a slight lift at the outer edge. A refined frame that complements prominent cheekbones without competing with them.

Glasses for an oblong or rectangular face

If your face is noticeably longer than it is wide, the objective is to add width and reduce the vertical emphasis. Frames with taller lenses and more horizontal presence help create the impression of a wider, more balanced face.

Avoid very narrow or very elongated shapes. Oversized and round styles are often the most effective.

Try: oversized, round, tall lenses, bold silhouettes.

Jimmy Fairly pick: The Greg, a wide, relaxed frame with enough presence to break up the length of longer features. Slim enough to stay refined, substantial enough to make a difference.

How to check fit when you try them on

Face shape gives you a starting point. Fit determines whether a frame actually works on you. When trying on glasses, run through these checks:

Your eyebrows should not be fully hidden behind the top of the frame.
Your cheekbones should not touch the frame when you smile.
The frame should fall between the outer corner of your eye and the tip of your temple.
Your eyelashes should not brush against the lenses.
Your eye should be reasonably centred within the lens opening.

A note on proportions

Beyond face shape, a few practical proportions are worth keeping in mind:

Frame width: the frame should roughly align with your cheekbones. Going significantly wider or narrower creates imbalance.
Bridge fit: the bridge should sit comfortably on your nose without pinching or sliding.
Lens height: taller lenses suit longer faces and are also useful for progressive prescriptions.
Weight: for everyday frames, lighter construction makes a consistent difference over a full day of wear.

Final thoughts

The right glasses for your face shape are the ones that feel like a natural extension of your features, not a correction of them. Face shape is a useful starting point, but the goal is always a frame that you stop noticing after the first hour.

Frequently asked questions

Stand in front of a mirror and compare the width of your forehead, cheekbones and jaw. The widest point and the shape of your jaw are usually the most telling. If you are unsure, the Jimmy Fairly Faceguide men and Faceguide women can help you identify your shape and explore matching frames.

Yes. The same balance principles apply to both. The main practical difference is that optical frames are worn all day, so fit and weight matter even more than they might for an occasional pair of sunglasses.

Angular, rectangular and geometric frames work best for round faces. They add structure and elongate the face, creating contrast with the natural softness of rounder features. Avoid very circular or very small frames.

Soft, rounded shapes: oval, round, and gentle cat-eye are the most flattering for square faces. They balance the strong jaw and angular features without reinforcing them.
