Short answer: The contrast rule applies - choose a frame with a shape that is the opposite of your face. A round face → angular/square frame. A square face → round/oval frame. A heart shape → a low center of gravity. An oblong face → a taller frame. The oval face carries almost anything.

Your eyeglasses frame is the most subtle accessory you wear every day, all day long. Chosen well, it balances your features and enhances your face. In this guide you will find which
eyeglasses frame suits each face shape.
Step 1: Find your face shape
In front of the mirror, notice two things: the
widest point (forehead, cheekbones or jaw) and the
length relative to the width. This leads you to one of the basic shapes: round, square, oval, heart (inverted triangle) or oblong.
Step 2: The contrast rule
The golden principle:
the frame should have a shape opposite to your face, for balance. An angular face is "softened" by a round frame; a round face gains structure with an angular frame. The goal is harmony, not excess.
Detailed table: face shape → frame
| Face shape | Ideal frame | Avoid |
| Round | Square, rectangular, angular | Round, small lenses |
| Square | Round, oval, slightly slim | Strongly angular, heavy frames |
| Oval | Almost anything - balanced sizes | Overly large frames |
| Heart (wide forehead) | Low center of gravity, rounded bottom, rimless | Heavy top part, cat-eye |
| Oblong | Taller frame, decorative temples | Small, narrow lenses |
Step 3: Size & proportion
Even the right shape falls flat if the size does not fit. The
frame width should ideally equal the width of your face, and your eyes should sit roughly at the
center of the lens. The three numbers on the inside of the temple (e.g. 52□18-140) tell you the exact dimensions - learn what the
numbers on your glasses mean.
Step 4: Frame color & material
Color brings out your skin, eye and hair color - warm tones (tortoiseshell, gold) for warm complexions, cool tones (silver, black, blue) for cool ones. The material changes the feel and weight: lightweight
titanium, colorful
acetate, slim
metal or discreet
rimless. Read our detailed guide on
frame materials: titanium, acetate or metal.
Browse & choose by category
Start with
men's eyeglasses or
women's eyeglasses. For a discreet, extremely lightweight frame see
Lindberg and
Silhouette (rimless). If you prefer to choose based on personality, also read the article

FAQ: Eyeglasses Frame & Face Shape
How do I find my face shape?
Look at the widest point (forehead, cheekbones or jaw) and the length. Round: equal width and length. Square: strong jawline. Oval: balanced. Heart: wide forehead, narrow jaw. Oblong: length > width.
What is the basic rule?
The contrast rule: choose a frame with a shape opposite to your face. Round face → angular frame; angular face → round/oval frame. An oval face carries almost anything.
Does frame size matter?
Yes - the frame width should match the width of your face and your eyes should sit roughly at the center of the lens. Learn what the numbers on the inside of the temple mean.
Does frame color matter?
Color does not change the shape but brings out skin/eyes/hair: warm tones (tortoiseshell, gold) for warm complexions; cool tones (silver, black) for cool ones.
Does the same rule apply to sunglasses?
The contrast logic is the same, but with sunglasses the sizes are more of a statement. See the guide on sunglasses & face shape.
