How to Identify Your Face Shape

Before choosing frames, you need to know your face shape. Here's the quickest way:

  1. Pull your hair back so your full face is visible
  2. Look straight into a mirror (or take a photo)
  3. Trace the outline of your face mentally, noting the widths of your forehead, cheekbones and jaw, and the length of your face

The main face shapes are: Oval, Round, Square, Oblong/Rectangle, Heart, Diamond and Triangle.

Oval Face Shape

Characteristics: Balanced proportions, slightly wider cheekbones, gently rounded jawline, forehead slightly wider than jaw.

Oval is considered the most versatile face shape - almost any frame style works well.

Best frames for oval faces:

  • Rectangular frames - add structure to soft features
  • Wayfarer / square frames - emphasise your natural balance
  • Aviators - complement the gentle curve of an oval face
  • Round frames - work well on oval, adding a soft, intellectual look

Avoid: Frames that are too large and overwhelm your face proportions.

Round Face Shape

Characteristics: Face length and width are roughly equal, soft curved jaw, full cheeks, rounded chin.

The goal with a round face is to add definition and make the face appear longer and slimmer.

Best frames for round faces:

  • Rectangular frames - the most flattering; they elongate the face and add angular contrast
  • Square frames - add structure and definition to soft features
  • Browbar / semi-rimless frames - draw the eye upward, creating the illusion of length
  • Angular cat eye frames - add drama and lift

Avoid: Round frames (they echo the face shape and make it look rounder), small frames, and very wide frames that exaggerate width.

Square Face Shape

Characteristics: Strong, angular jawline roughly equal in width to the forehead, broad forehead, defined features.

The goal is to soften the angles and add some curve to balance the sharp lines.

Best frames for square faces:

  • Round frames - the classic choice; circular lenses beautifully counterbalance angular features
  • Oval frames - soften without being too dramatic
  • Cat eye frames - add an upward curve that lifts the face
  • Thin metal frames - delicate frames look refined against strong features

Avoid: Square or rectangular frames (they echo and emphasise the jaw's angularity), very boxy frames, heavy acetate frames.

Oblong / Rectangle Face Shape

Characteristics: Face is notably longer than it is wide, with a long straight cheek line. Forehead, cheeks and jaw are similar widths.

The goal is to add width and make the face appear shorter and fuller.

Best frames for oblong faces:

  • Oversized frames - add width and proportion beautifully
  • Round or square frames - their wide, full shape adds width to the face
  • Decorative temples - frames with prominent sides (thick arms) add perceived width
  • Low bridge frames - help visually shorten a long face

Avoid: Small frames, narrow rimless glasses, and frames with a strong vertical depth that elongate the face further.

Heart Face Shape

Characteristics: Wide forehead and cheekbones that taper down to a narrow, pointed chin. Like an inverted triangle.

The goal is to minimise the width at the top and add width at the bottom of the face.

Best frames for heart faces:

  • Bottom-heavy frames - frames that are wider at the bottom visually balance a wide forehead
  • Light, rimless or semi-rimless frames - reduce visual weight at the top of the face
  • Round frames - soften the pointed chin and balance the face
  • Oval frames - work extremely well on heart shapes

Avoid: Cat eye frames (they exaggerate the wide forehead), decorative heavy brows, oversized frames that emphasise the top-heavy shape.

Diamond Face Shape

Characteristics: Narrow forehead and jaw, with dramatic wide cheekbones - the widest point of the face. Pointed chin.

The goal is to soften the cheekbones and add width to the forehead and chin.

Best frames for diamond faces:

  • Cat eye frames - broaden the forehead and complement high cheekbones beautifully
  • Oval frames - softened curves balance the angular cheekbone structure
  • Browbar / semi-rimless frames - add width to the forehead area
  • Rimless frames - don't compete with the face's natural drama

Avoid: Narrow frames, geometric frames that emphasise the sharpness of the cheekbones.

Triangle / Pear Face Shape

Characteristics: Narrow forehead that widens significantly toward the jaw and chin. Opposite of the heart shape.

The goal is to add width and visual interest at the top of the face.

Best frames for triangle faces:

  • Cat eye frames - draw attention upward and widen the top of the face
  • Browbar frames - the heavier top rim adds visual weight to the forehead
  • Decorative or coloured top-rim frames - any detail at the top helps balance the wider jaw
  • Aviators - the broad top bar works well

Avoid: Bottom-heavy frames, frames that are wider at the bottom, rimless glasses.

Other Things to Consider

Frame size: The frame should be roughly as wide as the widest part of your face. If the temples extend beyond your face outline, the frame is too big.

Bridge fit: The bridge should sit comfortably on your nose without pinching. If you have a low nose bridge, look for frames with adjustable nose pads.

Colour: As a general rule, frame colours that contrast with your skin tone tend to stand out and make a bolder statement. Colours that are close to your skin tone look more understated and versatile.

Frequently Asked Questions

What if my face doesn't fit neatly into one shape?

Most people are a blend of two shapes. Use the dominant features (e.g. a strong jaw + round cheeks) to guide your choice. The key principle is contrast - choose a frame shape that balances your most prominent feature.

Does face shape matter more for men or women?

The principle is the same for everyone. The frame styles that suit each shape don't change - though the specific styles you choose (a cat eye vs a browbar, for example) may reflect personal taste.

My optician said any frame works. Is face shape advice just a myth?

It's more of a guideline than a rule. You should always choose what you feel confident in. That said, understanding face shape and frame balance is a genuine styling principle that most optical professionals use - it just doesn't override personal preference.

Can I return glasses if they don't suit me?

Yes - Optically offers easy returns within 60 days. So even if you're not sure, you can try a pair with confidence.
