How to choose the shape of your glasses to suit your face
Isolani’s professional guide to enhancing your face with the right frames
Choosing the shape of your glasses isn’t just a matter of aesthetics: it’s about balance, proportion and harmony. At Isolani Opticians, we help people every day who want to enhance their facial features with frames that reflect their style, personality and comfort.
This guide sets out the professional criteria we use in our Opticians’ Centres and at the Isolani Boutique to help you find the frame shape that best suits your face, in a clear, straightforward and non-technical way.

1. How to work out your face shape
Before choosing a frame, it is helpful to identify your face shape by looking at your facial proportions, forehead, cheekbones and chin. The main categories are:
- Oval
- Round
- Square
- Rectangular / Elongated
- Triangular / Heart-shaped
- Diamond
If you’re unsure about your eyesight, at Isolani Opticians we carry out a professional assessment based on lines, balance points and actual visual behaviour.
2. Glasses for oval faces
An oval face shape is the most versatile: almost any frame looks good on it.
Island Tips: Square frames to add character, round frames for a softer look, and oversized glasses for a fashionable look.
Things to avoid: shapes that are too tight and throw the proportions off balance.
3. Glasses for round faces
Aim: to slim and tone.
Island Tips: square frames, rectangular shapes, clean, angular lines.
Things to avoid: round frames or frames that are too thin.
4. Glasses for square faces
Aim: to soften the facial features.
Island Tips: round frames, oval shapes, slim profiles.

5. Glasses for rectangular / elongated faces
Objective: to balance the vertical alignment.
Island Tips: High-rimmed frames, round or oval shapes, glasses with a low bridge.
Things to avoid: frames that are too tight.
6. Glasses for triangular / heart-shaped faces
Aim: to balance a broad forehead with a narrow chin.
Island Tips: Lightweight frames, oval shapes, soft cat-eye styles.
Things to avoid: heavy frames at the top.
7. Glasses for diamond-shaped faces
Aim: to enhance the cheekbones and create a harmonious silhouette.

8. Materials and colours: how to choose
Shape is important, but materials and colours also influence comfort and style.
