Choosing the right eyewear isn't just about picking a style you like — it's about finding frames that genuinely complement your natural features. Whether you're shopping for optical frames or sunglasses, understanding eyewear for face shape is the single most useful skill you can develop before spending money on designer glasses. In this guide, we'll walk you through every major face shape, the frame styles that work best for each, and a few expert tips to help you shop with confidence.
Why Face Shape Matters When Choosing Eyewear
Your face is the backdrop for every pair of glasses you wear. The goal isn't to follow rigid rules — it's to create balance. Frames that contrast with your natural face shape tend to be the most flattering, while frames that echo your features can sometimes make them appear more exaggerated.
There are six commonly recognised face shapes: oval, round, square, heart, oblong (or rectangular), and diamond. Identifying yours takes less than a minute, and it can save you hours of trial and error — especially when shopping online.
To find your face shape, pull your hair back, look directly into a mirror, and observe the widest part of your face, the shape of your jaw, and the length of your face compared to its width. Or simply trace your face outline on a mirror with a dry-erase marker — the shape you draw tells you everything.
Best Frames for Oval Faces
If you have an oval face, consider yourself lucky — you can wear almost any frame style. The best frames for oval faces are those that maintain the face's natural balance rather than disrupting it. Oval faces are characterised by a gently rounded jawline, cheekbones that are slightly wider than the forehead, and a face length that's about one and a half times the width.
Great choices include:
- Wayfarers and square frames — add structure without overwhelming soft features
- Aviators — a timeless match for oval faces, especially in metal
- Round frames — can look stylish and retro on oval faces
- Oversized styles — work well as long as the frames don't extend beyond the widest point of the face
Brands like Ray-Ban, Gucci, and Tom Ford offer extensive ranges that suit oval faces beautifully. The main thing to avoid is frames that are too small — they can make an oval face appear larger by comparison.
Glasses for Round Faces: Adding Definition
Round faces have soft, curved lines with similar width and length measurements. The cheeks are full, the chin is rounded, and there's no strong angular definition. When choosing glasses for round faces, the goal is to add length and angularity to create contrast.
The best options include:
- Rectangular frames — the horizontal lines elongate the face and add structure
- Narrow frames with a strong bridge — draw the eye upward and create the illusion of a longer face
- Geometric shapes — hexagonal or angular frames add edges that contrast with round features
- Upswept cat-eye frames — especially flattering on women with round faces
Avoid small, round frames — they echo the shape of your face rather than balancing it, which tends to make the face look rounder. Also steer clear of very wide frames that are broader than your cheekbones, as this adds horizontal width you don't need.
Police, Tommy Hilfiger, and Karl Lagerfeld all have strong collections featuring the kind of clean rectangular and angular frames that work brilliantly for round faces.
Frames for Square Faces: Softening Strong Features
Square faces have a broad forehead, wide jaw, and strong, angular features — with roughly equal width at the forehead, cheeks, and jaw. Choosing frames for square faces means introducing curves to soften those hard lines and add some roundness.
Top picks include:
- Round or oval frames — the curves directly counterbalance angular jaw and forehead lines
- Cat-eye frames — the upswept outer edges draw attention upward and soften the jaw
- Rimless or semi-rimless frames — minimise the visual weight of the frame and let your features breathe
- Thin, lightweight frames — don't add extra bulk to an already strong structure
Avoid boxy, thick square frames — they mirror your natural features rather than complementing them. Heavy rectangular frames with sharp corners can make a square jaw look even more pronounced.
Versace, Salvatore Ferragamo, and Victoria Beckham offer elegant oval and round frames that are perfect for square-faced shoppers looking to soften their look.
Heart and Diamond Face Shapes
Heart-shaped faces are wider at the forehead and taper down to a narrow chin. The aim here is to balance a wider top with added width at the bottom. Bottom-heavy frames — styles that are wider at the base than the top — work especially well. Cat-eye frames can be hit or miss; look for styles with understated, not dramatically flared, outer edges. Avoid top-heavy frames or those with heavy embellishments on the upper rim, as these draw attention to an already prominent forehead.
Diamond faces are narrow at the forehead and chin but wide at the cheekbones. This is a relatively rare face shape. Oval, rimless, and cat-eye frames tend to be the most flattering — they highlight the cheekbones while softening the overall outline. Avoid narrow or very small frames, which can make prominent cheekbones look even wider.
Oblong and Rectangular Faces
Oblong faces are longer than they are wide, with a straight cheek line. The goal is to add width and break up the vertical length. Deep frames with decorative temples work well, as do oversized styles and round shapes. Avoid narrow, elongated frames that emphasise the face's length. Wide frames — especially those with strong horizontal lines — help create the illusion of a shorter, wider face.
Brands like DKNY, Celine, and Loewe have excellent wide-frame collections that suit oblong faces particularly well.
Colour and Material: The Final Layer of Personalisation
Once you've identified your face shape and the frame styles that suit it, colour and material become your next consideration. A few general pointers:
- Warm skin tones (golden, peachy, or olive undertones) pair well with warm frame colours — tortoiseshell, gold, warm brown, and earthy greens
- Cool skin tones (pink or bluish undertones) suit silver, black, grey, blue, and pink frames
- Acetate frames offer the widest range of colour and pattern options and have a slightly heavier, premium feel
- Metal frames tend to be lightweight and minimalist, lending themselves to a clean, professional look
- Titanium and mixed-material frames are ideal for people who need to wear glasses all day — they're light, durable, and comfortable
Shopping for Eyewear Online: Tips to Get It Right
Buying glasses online can feel intimidating without the ability to try frames in person — but with a bit of preparation, it's very manageable. Here are a few steps that help:
- Measure your current frames — the numbers printed on the inside of your existing glasses (e.g. 52-18-140) refer to lens width, bridge width, and temple length. Use these as a starting reference.
- Check the frame dimensions listed on each product page and compare them to your measurements
- Read the description carefully — frame fit categories (narrow, medium, wide) are often noted
- Look at lifestyle photos — model shots give a much better sense of scale than product-only images
At Opticare Store's optical frames collection, every product listing includes detailed measurements and multiple image angles to help you make the right call from home.
