Choosing glasses by face shape takes about two minutes once you know the rule: contrast and fit. Angular frames add definition to soft, round faces; rounded frames soften strong, angular ones; and whatever the shape, the frame should be about as wide as your face. That's the whole system — the rest of this guide shows you how to find your face shape, which frames suit each one, and how to turn the answer into a shortlist of designer eyeglasses you can actually buy.
How to Find Your Face Shape
The mirror test
Stand square to a mirror and trace your face's outline with a dry-erase marker or lipstick — or take a straight-on selfie and study the outline. You're comparing four things: forehead width, cheekbone width, jaw width, and face length against its width.
Three widths, one length
Widest at the cheekbones with a gently tapering jaw and a face longer than it is wide — that's oval. Similar widths everywhere with a face about as long as it is wide — round. Similar widths with a strong, angular jaw — square. Wider forehead narrowing to the chin — heart. Widest at the cheekbones with a narrower forehead and jaw — diamond. Most people are a mix; pick the closest and focus on the features you want to balance.
| Face shape | Key traits | Best frames | Avoid |
|---|---|---|---|
| Oval | Balanced proportions, face longer than wide | Almost any: square, aviator, cat-eye, round, rimless | Frames wider than the face; oversized depth |
| Oblong | Long face, straight cheek line | Deeper frames, decorative temples, lower bridge | Short, narrow lenses |
| Round | Soft curves, width ≈ length | Square, rectangle, upswept cat-eye | Small, very round frames |
| Square | Strong jaw, broad forehead | Round, oval, pillow; thin rims | Boxy frames as wide as the jaw |
| Heart | Wide forehead, narrow chin | Light, rimless or bottom-weighted; soft aviators | Top-heavy, decorated brows |
| Diamond | Widest at cheekbones | Cat-eye, oval; brow detail | Narrow frames that pinch the cheekbones |
Oval and Oblong Faces
Oval: the most flexible shape
Oval faces suit almost every frame — the job is simply not to break the balance. Keep the frame about as wide as the widest part of your face, and avoid very deep lenses that shorten it. Rimless and semi-rimless frames sit especially well on oval faces. A clean oval frame like the Emporio Armani EA1059 is the low-risk, high-polish pick.
Oblong: add width, reduce length
A longer face wants frames with more lens depth, a lower bridge, and some visual interest at the temples to add width. A phantos shape — rounded with a subtle brow line — like the Burberry BE2365 Alisson does exactly that.
Round Faces
Why angles work
Round faces gain structure from straight lines: square and rectangular frames sharpen the features, and a frame slightly wider than the cheeks slims the face. Browse square eyeglasses for the full range — a confident square like the Burberry BE2457U is the textbook choice. What to skip: small, very round lenses that repeat the face's curve.
Do cat-eyes suit round faces?
Yes — it's one of the most common questions and the answer is a clear yes. The upswept corners of a cat-eye pull the eye outward and upward, adding lift and definition. The Versace VE3353 shows how an angular cat-eye structures a soft face.
Square Faces
Soften a strong jaw
Where round faces need angles, square faces need curves: round, oval and pillow shapes take the edge off a strong jawline, especially in thinner metal or softly rounded acetate. Start with round eyeglasses.
Best frame shapes
The pillow shape — a rounded-off square — is the sweet spot: enough structure to feel current, enough curve to soften. The Prada Linea Rossa PS 51SV and PS 06RV are both pillow frames built on exactly this logic. Avoid boxy frames as wide as the jaw — they double down on the angles.
Heart and Diamond Faces
Heart: balance a wider forehead
A heart-shaped face — wider at the forehead, narrowing to the chin — balances best with frames that keep visual weight low: rimless, light metals, bottom-weighted rims, and soft aviator shapes in sunglasses.
Diamond: highlight cheekbones
Diamond faces, widest at the cheekbones, are made for cat-eye eyeglasses — the upswept line echoes the cheekbones while brow detail widens the upper face. A refined cat-eye like the Versace VE3367U does both. As a rule, cat-eyes flatter heart, diamond and round faces alike.
Beyond Shape: Size, Colour and Sunglasses
Frame width and bridge fit
Shape advice fails when the size is wrong, so size comes first: your eyes should sit roughly centred in each lens, the frame should end about where your temples do, and the bridge should rest without gaps or pinching. The size is printed inside the temple arm as three numbers — lens width, bridge, temple length in millimetres. If frames tend to slide down your nose, look for low-bridge fit versions — often marked with an F in the model code — which sit higher and more securely on a lower nose bridge.
Colour and skin tone
Warm undertones pair naturally with havana, tortoise, gold and brown frames; cool undertones with black, grey, silver and crystal. When in doubt, tortoise and black are the two finishes that work on nearly everyone.
The same rules for sunglasses
Everything above applies to sunglasses too — contrast the shape, match the width. A rounded phantos sunglass like the Emporio Armani EA4152 softens angular faces exactly the way a round optical frame does, which matters in the UAE, where sunglasses are the half of your eyewear you wear most.

Frequently asked questions
What glasses suit an oval face?
Almost any shape: square, rectangle, aviator, cat-eye or round. Keep the frame as wide as the widest part of the face and avoid oversized depth.
Which face shape suits rimless glasses?
Rimless and semi-rimless frames suit oval and heart faces best, and they are a light option for square faces that want less visual weight.
What face shape do cat-eye glasses look good on?
Cat-eyes suit heart, diamond and round faces; the upswept corners add lift and definition.
Do cat-eye glasses look good on round faces?
Yes. Angular, upswept cat-eyes add structure to a round face; choose a frame slightly wider than the cheeks.
How do I know my face shape?
Compare the width of your forehead, cheekbones and jaw, and your face length against its width, using a mirror outline or a straight-on selfie.
