If you have a square face, the best sunglasses usually do one thing well: they soften strong angles without making your features disappear. That means looking for frames with rounded edges, oval lenses, gentle curves, or a slightly lifted shape that balances a defined jawline and broad forehead.
Quick Answer: What sunglasses suit a square face best?
If you want the short version, start here:
- Best shapes: round, oval, soft cat-eye, and gently curved frames.
- Best effect: soften a strong jaw and add contrast to straight cheek and brow lines.
- Usually less flattering: very boxy frames that repeat the same hard angles as your face.
- Best starting point at By Our Bias: browse the Round collection for shapes that feel softer on the face.
In practice, the best sunglasses for square face shapes are the ones that bring curve, lift, and a little breathing room around the face. You do not need to avoid structure entirely. You just want enough softness to create balance.
How to tell if you have a square face
Square faces typically have a broad forehead, similar width through the cheekbones, and a defined jawline. The face often looks quite balanced from top to bottom, but the edges read as straighter and sharper than oval or round face shapes.
If that sounds like you, sunglasses with rounded lines will usually feel easier to wear than anything too rigid or severe.
Why softer frames work so well
The goal is not to hide your features. Strong bone structure is often exactly what makes square faces look striking in sunglasses. The trick is to choose a frame that complements those lines instead of echoing every angle.
Rounder silhouettes create contrast. That contrast makes the overall look feel more balanced, polished, and effortless. It is why softly curved sunglasses often look better on square faces than sharp, flat-top styles.
The best sunglasses for square face shapes
1. Round sunglasses
Round sunglasses are usually the safest recommendation for square faces because they counterbalance angular features immediately. They can make the face look a little softer while still feeling intentional and fashion-led.
If you want an easy place to start, the Round collection is the most relevant edit. Standout options include Camera Optional, Airplane Mode, and Deniable Involvement.
2. Oval sunglasses
Oval frames work for similar reasons. They smooth the face visually and can feel a little more understated than a perfectly round frame. If you like a minimal, wearable everyday pair, oval shapes are often a strong choice.
3. Soft cat-eye sunglasses
A gentle cat-eye can be especially flattering if you want lift through the outer corners. The important word here is soft. You want the upsweep to feel elegant rather than harsh. Too much sharpness can bring you back into the same angular territory you are trying to balance.
4. Slightly oversized curved frames
If you like more coverage, slightly oversized frames can work beautifully on square faces, especially when the edges are rounded rather than boxy. Oversized sunglasses add drama, but the curve keeps the effect flattering.
If you want a broader everyday browse beyond one face-shape edit, the Core Collection is a good second stop.
What to avoid if you have a square face
There are no absolute rules, but a few frame details are more likely to feel awkward on square face shapes:
- very square lenses with hard corners
- flat-top frames with strong horizontal emphasis
- narrow frames that make the jawline look wider
- heavy geometric shapes with little curve
If you love a sharper style, keep some softness elsewhere: slightly rounded corners, a thinner frame, or a lens shape that is not perfectly boxy.
Colour and lens tips for square faces
Shape matters most, but colour can shift the feel of a pair too. Tortoiseshell, warm brown, olive, tea, and soft black usually look less severe than stark glossy black in an angular shape. If you want the easiest everyday option, warm neutrals tend to be forgiving and versatile.
For a polished look, try softer frame colours in rounded silhouettes first. For a bolder look, choose deeper lenses with a shape that still has curve.
Three easy By Our Bias picks to start with
- Camera Optional: a flattering rounded shape that keeps things easy and wearable.
- Airplane Mode: a stronger statement frame with enough softness to balance angular features.
- Deniable Involvement: a polished option if you want curve without going overly delicate.
How sunglasses should fit a square face
Even the best shape can look wrong if the fit is off. Aim for frames that sit comfortably across the bridge, do not pinch at the temples, and feel proportionate to your face width. A pair that is slightly wider than the widest part of your face often looks more balanced than one that cuts in too tightly.
If you usually struggle with narrow fits, it is worth comparing the frame proportions on product pages before you buy. Shape and width work together.
Final takeaway
The best sunglasses for square face shapes usually have one thing in common: softness. Round, oval, softly upswept, and curved frames help balance strong features while still letting your face keep its structure. If you want a shortcut, start with the Round collection and focus on styles that bring contrast instead of more angles.

Can square faces wear oversized sunglasses?
Yes, as long as the frame has some curve. Slightly oversized rounded or oval frames often look better than oversized boxy shapes.
What sunglasses should square faces avoid?
