How to Find Glasses for Your Face Shape: A Simple Guide

Buying glasses online doesn't have to be a guessing game. The secret to finding frames that look instantly flattering on you comes down to one golden rule: opposites attract. Round faces love sharp angles, while strong jaws shine in soft, rounded frames.

Step 1

Determine Your Face Shape

Pull your hair back, look straight into a mirror, and ask yourself three simple questions:

1. Widest Part?

Is your forehead, cheekbones, or jawline the widest part of your face?

2. Jawline Shape?

Is your chin gently rounded, sharply angular, or pointed?

3. Proportion Ratio?

Is your face noticeably longer than it is wide, or roughly equal in both dimensions?

Step 2

Matching Frames to Your Face Shape

Round Face

Soft curves, full cheeks, equal width and length.

Best Choice: Rectangular, square, cat-eye frames.

Avoid: Small round frames.

Square Face

Strong jawline, broad forehead, defined angles.

Best Choice: Round, oval, semi-rimless frames.

Avoid: Boxy, sharp angular frames.

Oval Face

Balanced proportions, slightly longer than wide.

Best Choice: Almost any shape works well!

Avoid: Overly wide or deep oversized frames.

Heart Face

Wide forehead, high cheekbones, delicate narrow chin.

Best Choice: Oval, aviator, subtle cat-eye.

Avoid: Heavy, top-heavy frames.

Diamond Face

Narrow forehead and chin, prominent wide cheekbones.

Best Choice: Round, oval, browline frames.

Avoid: Extremely narrow or sharp frames.

Oblong Face

Longer than wide with straight cheek lines.

Best Choice: Deep square, aviator, tall frames.

Avoid: Small or narrow horizontal frames.

Step 3

Check Your Frame Measurements

Shape is only half the secret—fit is just as crucial. Look at the inside temple arm of your current glasses for three numbers (e.g., 54 ▢ 18 - 145):

Lens Width (54 mm)

Horizontal width of one lens. Ensures your eyes sit centered.

Bridge Width (18 mm)

Distance over your nose. Prevents slipping or tight pinching.

Temple Length (145 mm)

Length of the frame arms wrapping comfortably around your ears.
