Learn how to pick sunglasses that flatter your face shape. This guide covers oval, round, square, heart, and diamond faces with practical tips.
Quick answer
To choose sunglasses that flatter your face, first determine your face shape—oval, round, square, heart, or diamond—then select frames that contrast its angles or curves.
Why face shape matters for sunglasses
The right sunglasses balance your natural features. Oval faces suit most styles, while round faces need angular frames to add definition. Square faces soften with curved or oval shapes. Heart-shaped faces look great with bottom-heavy frames, and diamond faces shine with cat-eye or oval designs.
Steps to choose sunglasses for your face shape
- Identify your face shape: Stand in front of a mirror and trace the outline of your face on the glass with a washable marker. Compare the shape to these categories: oval (balanced, slightly curved), round (equal width and length, soft curves), square (strong jaw, wide forehead), heart (wide forehead, narrow chin), diamond (high cheekbones, narrow forehead and chin). If you’re unsure, measure your face length and width at the cheekbones—oval faces are about one and a half times longer than wide.
- Match frame shape to your face: Oval: almost any frame works—try oversized or geometric. Round: choose angular or rectangular frames to add contrast. Square: go for rounded or oval frames to soften the jaw. Heart: pick bottom-heavy frames like cat-eye or aviators. Diamond: opt for oval or cat-eye frames that highlight cheekbones. Avoid frames that mirror your face shape—round faces look wider in round frames, and square faces appear boxier in square frames.
- Consider color and finish: Neutral tones like black or tortoiseshell suit most skin tones and outfits. Black frames (like The Blondie or The Florence) are versatile for daily wear. Emerald tortoiseshell (like The Joan) adds warmth and pairs well with earth tones or gold jewelry. If you have a cool skin undertone, stick with black or silver accents; warm undertones pop with tortoiseshell or gold.
- Check fit and comfort: Sunglasses should sit comfortably on your nose without sliding, and the arms should not pinch behind your ears. The frame width should match your face width—too wide and they’ll look oversized, too narrow and they’ll pinch. When trying online, measure your current favorite pair’s width and compare it to the product size guide.
