The biggest worry about buying spectacles online is fit: will the frame be too wide, pinch your nose, or slide down? The good news is that you probably already have the answer on your face. Almost every pair of glasses has its size printed on it. Here's how to read it.
Find the numbers on your current glasses
Take off a pair that fits you comfortably and look at the inside of the temple arm (the side piece), or sometimes the inside of the bridge. You'll see something like:
52 □ 18 – 140
These three numbers, all in millimetres, are the frame's size.
1. Lens width (e.g. 52)
The width of one lens, edge to edge. It's the number that most affects how big the frame looks on your face. Lens widths commonly range from about 45 mm (small) to 58 mm or more (large).
2. Bridge width (e.g. 18)
The gap between the two lenses, which sits over your nose. A bridge that's too narrow pinches; one that's too wide lets the frame slide down. Most bridges are between 14 and 24 mm.
3. Temple length (e.g. 140)
The length of the arm from the hinge to the tip that curves behind your ear. 135, 140 and 145 mm are the most common lengths.
How to use these numbers when shopping
- Write down the three numbers from the pair that fits you best.
- On a product page, compare them with the frame's lens width, bridge width and temple length.
- The closer the numbers, the more similar the fit. Lens width and bridge width matter most. Temple length is usually the easiest to adjust.
Where we have a frame's measurements, they're listed in the Specification section of its product page. If a frame's size isn't listed, message us on WhatsApp and we'll check it for you before you order.
No old glasses? A quick guide by face width
- Narrow face: look for smaller lens widths and a narrower bridge.
- Average face: a mid-size frame is a safe place to start.
- Wide face: larger lens widths, and check the overall frame width.
A simple check: when you look straight ahead, your eyes should sit roughly in the centre of each lens, and the frame shouldn't extend far beyond the sides of your face.
Frame shape and face shape
Size is about comfort. Shape is about style. As a loose starting point, many people find that angular frames balance a round face, and rounder frames soften a square jaw. There are no strict rules, though: pick what you like wearing. Browse by shape, such as rectangle, round or aviator, from our eyeglasses collection.
Material and weight
Acetate frames are made from a plant-based plastic that can be polished and shaped, and comes in rich colours. Metal frames are usually slimmer and lighter, often with adjustable nose pads, which helps if bridge fit is a concern.
