ShapeShades analyzes your face shape in seconds — camera selfie or 5-question quiz — and recommends the best sunglasses frame styles for you. Free, no account needed.
Not sure what your face shape is? Our AI face shape detector or quick quiz identifies whether you have an oval, round, square, heart, oblong, diamond, or triangle face, then matches you with the right sunglasses frames and shops them on Amazon.
Choosing sunglasses that flatter your face comes down to contrast: frames that balance your natural proportions. Oval faces are the most versatile — nearly any frame works. Square faces benefit from rounder, softer frames like aviators or oval styles. Round faces look best in angular frames like wayfarers or square shapes. Heart faces suit frames that are wider at the bottom, like aviators. Oblong or long faces benefit from wide, oversized frames that add horizontal width.
