How to Pick the Right Sunglasses for Your Face Shape
This sunglasses styles guide explains each major frame style, what defines it and which face shapes it flatters, so you can pick the right sunglasses for your face shape with confidence. Style names appear on almost every product listing but are rarely explained. Use this sunglasses styles guide as a glossary when you shop, search and filter.
Key Takeaways
- A sunglasses styles guide helps you match frame shape to face shape, which is the quickest route to a flattering pair.
- The general rule is contrast: angular frames balance round faces and curved frames soften angular ones.
- Aviator, square, cat-eye, round, oval, geometric, browline and wraparound are the main styles to know.
- Geometric and polygonal frames are newer styles that add angles to soft features.
- Fit and UV400 protection matter as much as style.
How to Use This Sunglasses Styles Guide
Start by identifying your face shape, then read the styles that suit it. Once you know the names, you can search for them directly and filter results faster. Our face shape guide for sunglasses and glasses explains how to measure your face if you're unsure.

The Main Sunglasses Styles Explained
Aviator
Aviators were originally designed for pilots in the 1930s, and their teardrop lenses were shaped to cover the eye's full range of movement. Thin metal frames and a double bridge keep them light. In any sunglasses styles guide, aviators are the classic all-rounder: they suit oval, square and heart-shaped faces especially well.
Square
Square frames have straight edges and a slightly wider top line, usually in thick plastic or acetate. They add structure to soft features, which is why this sunglasses styles guide recommends them for round and oval faces. They can look heavy on very angular faces.
Cat-eye
Cat-eye frames sweep upwards at the outer corners, a look that became popular in the 1950s. The lift draws attention to the cheekbones, which flatters round, heart-shaped and diamond faces. Subtle cat-eyes work for everyday wear; dramatic ones make a statement.
Round
Round frames have circular lenses, often in thin wire. They soften strong jawlines and broad foreheads, so they suit square, oblong and angular faces. On a round face, they can echo the curves too closely.
Oval
Oval frames sit between round and rectangular. Their gentle curves soften angular features without feeling as bold as round frames, which makes them a good choice for square and diamond faces.
Geometric and Polygonal Sunglasses: The Newer Styles
Geometric frames use hexagons, octagons and other multi-sided shapes. They're one of the least explained categories, so this sunglasses styles guide covers them in more detail. The extra angles add definition to round and oval faces, while thin metal versions feel lighter than thick plastic ones.
- Hexagonal: six sides, a softer geometric look that suits most oval faces.
- Octagonal: eight sides, closer to round but with crisp edges.
- Polygonal or irregular: bold, fashion-led shapes for confident styling.
Other Styles Worth Knowing
Browline
Browline frames have a bold upper rim and a thin or rimless lower edge. The strong top line balances a narrow forehead or a wide jaw, and suits oval, heart and diamond faces.
Wraparound and shield
Wraparound frames curve around the face, and shield styles often use a single large lens. They block light and wind from the sides, which makes them the go-to choice in any sunglasses styles guide for running, cycling and sport.
Oversized
Oversized frames cover more of the face, giving extra sun protection and a glamorous look. They suit oblong and oval faces best and can overwhelm smaller features.
Rimless and semi-rimless
Rimless frames have no full border around the lens, so they look light and understated. They work well on square and diamond faces and for anyone who wants a minimal look.
Clip-on and flip-up
Clip-on lenses attach to prescription glasses, and flip-up versions lift out of the way when you go indoors. They're a practical option if you wear glasses and don't want a second prescription pair, though they add a little weight to the frame. In this sunglasses styles guide, clip-ons are the budget-friendly choice for glasses wearers who spend short spells outdoors.
Sunglasses Styles Guide by Face Shape
| Face shape | Best styles | Use with care |
|---|---|---|
| Round | Square, geometric, cat-eye | Small round frames |
| Square | Round, oval, aviator, rimless | Heavy square frames |
| Oval | Most styles | Frames much wider than the face |
| Heart | Aviator, round, browline | Top-heavy decorative frames |
| Oblong | Oversized, round, tall square | Narrow, shallow frames |
| Diamond | Cat-eye, oval, rimless, browline | Very narrow frames |
How to Pick the Right Sunglasses: Beyond Style
A good sunglasses styles guide gets you to a shortlist. These checks get you to the right pair.
- Check the width: the frame should be about as wide as your face, with no gaps at the temples and no pinching.
- Check the brow line: the top of the frame should follow or sit just below your eyebrows.
- Check the bridge: the frame shouldn't slide down your nose or rest on your cheeks.
- Check protection: look for UV400 or 100 percent UVA and UVB on every pair.
- Check the tint: our sunglasses lens tint guide explains which lens colour suits your activities.
Common Mistakes When Choosing a Style
- Copying a style from a photo without checking it suits your face shape.
- Choosing frames much wider or narrower than your face.
- Buying a fashion style for sport, where a wraparound fits better.
- Ignoring UV protection because a style looks right.
- Following a trend instead of using a sunglasses styles guide to match frames to your features.
Use this sunglasses styles guide to learn the names, match them to your face shape, and then confirm the fit. That's how to pick the right sunglasses for your face shape every time.

Frequently Asked Questions
What does a sunglasses styles guide cover?
It names and explains the main frame styles, such as aviator, square, cat-eye, round, oval, geometric and wraparound, and shows which face shapes each one flatters. That makes it easier to search, filter and choose a pair that suits you.
What is the difference between aviator and square sunglasses?
Aviators have teardrop lenses and thin metal frames, often with a double bridge. Square frames have straight edges and usually thicker plastic or acetate. Aviators suit oval, square and heart faces; square frames suit round and oval faces.
Who suits cat-eye sunglasses?
Cat-eye frames flatter round, heart-shaped, diamond and oval faces, because the upswept corners lift the face and highlight the cheekbones. Subtle versions work for everyday wear.
What are polygonal sunglasses?
Polygonal or geometric sunglasses have multi-sided lenses, such as hexagons or octagons. Their angles add definition, so they suit round and oval faces especially well.
Which sunglasses style is best for sport?
Wraparound and shield styles are best for sport. They follow the curve of your face, block light and wind from the sides and stay put better during movement than most fashion frames.
