Frames & Face Shapes

Not all frames flatter every face. This guide takes the guesswork out of choosing glasses, whether you're shopping for the first time or updating your look.

Why Does Face Shape Matter When Choosing Glasses?

Your glasses sit front and centre on your face every single day. The right frame can enhance your best features, while the wrong one can feel off without you quite knowing why. Frames that contrast your face shape tend to bring balance, while frames that mirror it can amplify what's already there.

Think of angular frames adding definition to soft, rounded features, or curved frames softening a strong, angular jawline. This guide covers all six common face shapes, with frame recommendations to help you find the best glasses frames for your face shape. With honest advice on what to avoid.

Don't worry if you're between shapes. Most people are a blend, and personal style always trumps any rule. Use this as your starting point, not a strict prescription.

How to Identify Your Face Shape

  1. Pull your hair back away from your face so your full outline is visible
  2. Look in a mirror straight on, or take a front-facing selfie
  3. Note the widest point of your face, forehead, cheekbones, or jaw?
  4. Assess your chin, rounded, square, or pointed?
  5. Consider your face length, is it roughly as wide as it is long, or notably longer?
  6. Compare to the six shapes below, pick the closest match

Best Glasses Frames for Every Face Shape

Use the guides below to match your face shape to the most flattering frame styles. Each section includes what to look for, what to avoid, and a celebrity example to bring it to life.

Face Shapes

Glasses for an Oval Face Shape

An oval face is gently elongated. With balanced proportions and a forehead slightly wider than the jawline, tapering softly at the chin. It's widely considered the most versatile face shape for glasses. Almost any frame works beautifully.

Your goal is simply to maintain that natural balance rather than break it.

Best Frame Styles

✓ Bold geometric & square frames

✓ Oversized styles

✓ Round & circular frames

✓ Cat-eye with upswept corners

✓ Aviator styles

✓ Thick acetate statement frames

Frames to Avoid

X Frames much narrower than face width

X Very small frames that look undersized

X Overly boxy styles that break natural balance

What Glasses Suit a Round Face?

A round face has soft, curved lines with similar width and length measurements, full cheeks, and a gently rounded chin and hairline.

The aim when choosing glasses is to add definition and create the impression of length. Making the face appear more elongated and structured.

Best Frame Styles

✓ Rectangular & square frames

✓ Angular, geometric styles

✓ Frames with a strong brow line

✓ Wayfarer-inspired shapes

✓ Semi-rimless with angular top bar

✓ Narrow bridge to lengthen the nose

Frames to Avoid

X Round or oval frames (echo face shape)

X Very small frames

X Low-set nose bridges

X Rimless styles that add no contrast

Best Glasses Frames for a Square Face

A square face has a broad, defined forehead, wide jawline, and a squarish chin with roughly equal width and length. The strong, angular features are striking, but the right frame softens the lines rather than competing with them. Curved and rounded styles are your best friends here.

Best Frame Styles

✓ Round & oval frames

✓ Cat-eye styles

✓ Thin rims in neutral tones

✓ Rimless & semi-rimless

✓ Circular retro acetate frames

✓ Oversized with rounded edges

Frames to Avoid

X Square or rectangular frames

X Angular, geometric styles

X Heavy boxy frames

X Small frames that look too narrow

What Glasses Suit a Heart-Shaped Face?

A heart face shape (sometimes called an inverted triangle shaped face) has a broad forehead and high cheekbones tapering to a narrower. With often pointed chin. It can also feature a widow's peak hairline. The aim is to add visual weight to the lower half of the face and avoid emphasising the already-wider forehead.

Best Frame Styles

✓ Frames wider at the bottom

✓ Light-coloured or rimless styles

✓ Oval frames (don't over-emphasise cheekbones)

✓ Aviator styles

✓ Cat-eye (subtle, not over-the-top)

✓ Round frames for men

Frames to Avoid

X Heavy top-heavy frames

X Decorative detail concentrated at the brow

X Very wide frames that add forehead width

X Narrow or rectangular styles

Best Glasses for a Diamond Face Shape

A diamond shaped face has dramatic, wide cheekbones with a narrow forehead and chin, often described as 'chiselled'. It's considered one of the rarer and more glamorous face shapes. A pair of glasses that accentuate your eyes and soften the prominent cheekbones work best, without overwhelming the narrower parts of your face.

Best Frame Styles

✓ Cat-eye frames (accentuate eyes)

✓ Oval & round frames / Rimless & semi-rimless

✓ Aviator styles

✓ Browline frames

✓ Frames with detail at the top

Frames to Avoid

X Narrow or small frames

X Overly angular styles

X Frames much wider than your cheekbones

X Very boxy, oversized styles

Best Glasses for an Oblong Face Shape

An oblong (or rectangular) face is longer than it is wide, with a long, straight cheek line and similar forehead, cheekbone, and jaw widths. The aim is to add the impression of width to the facial features and break up the vertical length. Bold, wide frames with good depth and decorative detailing are ideal.

Best Frame Styles

✓ Wide, bold square frames

✓ Oversized & aviator styles

✓ Frames with decorative temple detail

✓ Upswept cat-eye shapes

✓ Frames with good lens depth

✓ Contrasting coloured arms

Frames to Avoid

X Narrow rectangular frames (elongate face)

X Small or understated styles

X Rimless frames that add no width

X Frames with no decorative detail

5 More Tips for Choosing Glasses That Fit

Tip What to look for Why it matters
Check Frame Width Frames should match the widest part of your face; check lens width (e.g. 52mm) Ensures a balanced, comfortable fit
Bridge Fit Matters Bridge should sit comfortably without pinching or slipping; consider adjustable nose pads for low bridges Prevents discomfort and slipping
Consider Lens Height Choose deeper lenses if you wear varifocals Allows full use of reading and distance zones
Match Your Prescription Strong prescriptions work best with smaller lenses and thicker frames Helps keep lenses thinner and more attractive
Use Your Existing Frames Use measurements from a pair that already fits well Makes online ordering easier and more accurate

Frequently Asked Questions

What glasses suit my face shape?

The best frames for your face shape are those that contrast and balance your natural features.

As a rule:
Round faces suit angular frames.
Square faces suit rounded or oval frames.
Oval faces suit almost anything.

Heart-shaped faces suit lighter bottom-heavy styles.

Oblong faces suit wide bold frames.

Diamond faces suit cat-eye or oval styles.

How do I find out my face shape for glasses?

Pull your hair back and stand squarely in front of a mirror. Note where your face is widest. At the forehead, cheekbones, or jaw and whether your chin is rounded, square, or pointed.

You can also take a straight-on selfie and compare the proportions to the six common shapes: oval, round, square, heart, diamond, and oblong. Don't worry if you're somewhere between two shapes, that's completely normal.

What are the best glasses frames for an oval face?

Oval faces are the most versatile, almost any frame style works well. Bold, geometric, oversized, square, round, and cat-eye frames all suit oval faces. The key is to choose frames that are roughly as wide as the broadest part of your face, so as not to throw off your natural proportions.

If in doubt, go bold! Oval faces can carry striking statement frames beautifully.

What glasses frames suit a round face?

Rectangular, square, and angular frames work best for round faces. These add definition and create contrast against soft, curved features, making the face appear longer and more structured. Avoid round or oval frames, which tend to echo the face shape and make it appear fuller. A strong brow line or angular top rim also helps elongate the appearance of the face.

What glasses frames suit a square face?

Round, oval, and cat-eye frames are the most flattering for square faces, as their curves soften a strong jawline and angular features. Avoid square or rectangular frames that mirror the face's existing angles. Thinner rims in neutral or warm tones tend to create a softer, more balanced appearance overall.

What glasses suit a heart-shaped face?

Heart-shaped faces also known as triangle face shape, suit frames that are wider at the bottom or light rimless styles. Frames that draw the eye downward rather than emphasising the top of the face. Oval frames, aviators, and subtle cat-eyes work well. Avoid heavy, decorative frames that add more visual weight to the forehead area.

What glasses suit a diamond face shape?

Diamond faces suit oval, cat-eye, browline, and rimless frames that accentuate the eyes and help balance wide cheekbones. Frames with detail or interest at the top (like browlines) draw focus upward and soften the cheekbones. Avoid very narrow frames or heavily angular styles that can make the cheekbones appear even more pronounced.

What glasses suit an oblong face?

Oblong faces suit wide, bold frames with good lens depth and decorative temple details that add visual width to the face. Oversized styles and aviators can also work well. Avoid narrow or rectangular frames that elongate the face further. Frames with contrasting arm colours are a great way to draw the eye outward and create the impression of greater width.

Can I order prescription glasses online in the UK without visiting a store?

Yes, at Direct Sight (directsight.co.uk) you can order prescription glasses entirely online using your existing valid UK prescription. Simply browse our frame collection, select your lenses, and enter your prescription details at checkout. Our UK-based team glaze your chosen frames and dispatch directly to your door. You will require an up-to-date prescription from a registered UK optician.

How do I measure my frame size when shopping for glasses online?

Frame measurements are printed on the inside of the temple arm (the arm that goes over your ear). Look for three numbers, for example, 52-18-140, which correspond to the lens width, bridge width, and temple length in millimetres.

If you already own a pair that fits comfortably look for similar measurements when browsing online. All our frames at Direct Sight include full size specifications on the product page.

Are there rules about which frame colours suit different face shapes?

Frame shape matters more than colour for face flattery, but colour does play a role. Lighter, more transparent frames (blush, clear, light tortoiseshell) create a softer, less defined look, which suits heart and diamond faces well. Darker, bolder frame colours add more contrast and definition, which works well for round and oval faces. Ultimately, wear what makes you feel most confident, there are no hard rules.  For more details visit our frame colour guide.
