Why publish this
Sunglasses sizing is discussed almost entirely in adjectives. Frames are described as oversized, petite or regular, and none of those words carries a measurement.
Meanwhile every frame has three numbers printed inside the temple arm, and almost nobody uses them, largely because there is no published reference for what is normal.
This report addresses that gap. The figures below are drawn from a full Indian sunglasses catalogue and are expressed as percentage distributions so they remain meaningful as any catalogue changes.
Lens width: where sizes actually cluster
Lens width is the first of the three numbers and the one that most determines whether a frame looks proportionate on your face.
| Lens width | Share of catalogue |
|---|---|
| Under 48 mm | 11.9% |
| 48 to 52 mm | 35.3% |
| 52 to 56 mm | 40.3% |
| 56 to 60 mm | 9.7% |
| 60 mm and above | 2.8% |
Three quarters of the catalogue sits between 48 and 56 mm, with the median at 52 mm. That is the practical centre of the market.
The tails matter more than their size suggests. Under 48 mm accounts for roughly one frame in eight, which is the working range for smaller and narrower faces. Above 60 mm is under three percent, which is why people with wider faces often struggle: the supply genuinely is thin, not just their luck.
Bridge width: the most evenly spread measurement
Bridge width is the second number and it determines where the frame sits on your nose and whether it slides.
| Bridge width | Share of catalogue |
|---|---|
| Under 18 mm | 20.6% |
| 18 to 20 mm | 25.6% |
| 20 to 22 mm | 24.4% |
| 22 mm and above | 29.4% |
This is the most evenly distributed of the measurements, spread across four bands with no single one dominating. The median sits at 20 mm and the full range runs from 12 to 26 mm.
That spread is useful news, because bridge fit is where most comfort problems originate. If frames slide down your nose, the bridge is too wide for you, and the data shows there is genuine choice at the narrower end rather than a token few options.
Temple length: less variation than expected
Temple length is the third number and it is the most standardised of the three.
| Temple length | Share of catalogue |
|---|---|
| Under 140 mm | 5.9% |
| 140 to 145 mm | 48.1% |
| 145 to 150 mm | 32.8% |
| 150 mm and above | 13.1% |
Nearly half the catalogue falls in a five millimetre band from 140 to 145 mm, with a median of 144 mm. The full range runs only from 125 to 152 mm.
This concentration explains a common frustration. Because temple length varies so little, people whose heads sit outside the middle have far fewer options than the overall catalogue size implies. It is also why temple adjustment at the tip matters: it is doing work that the length distribution cannot.
Lens height and frame width
Two further measurements are not in the printed three-number string but affect fit substantially.
| Lens height | Share of catalogue |
|---|---|
| Under 42 mm | 13.4% |
| 42 to 48 mm | 42.5% |
| 48 to 54 mm | 38.1% |
| 54 mm and above | 5.9% |
Lens height has a median of 47 mm across a range from 34 to 65 mm. It matters for two reasons: coverage of the skin around the eye, and whether a frame can take progressive lenses, which need vertical depth.
Total frame width runs from 136 to 170 mm with a median of 145 mm. This is the measurement to compare against your own face width, and it is the single most reliable predictor of whether a frame will sit correctly.
Shape distribution
The catalogue's shape mix shows where design attention concentrates.
| Shape | Share of catalogue |
|---|---|
| Square | 26.0% |
| Rectangle | 19.7% |
| Wayfarer | 9.4% |
| Aviator | 6.0% |
| Round | 6.0% |
| Wrap around | 4.1% |
| Hexagon | 3.8% |
| Oval | 3.4% |
Angular shapes together account for nearly half of everything available. Round and oval combined are under ten percent, which is worth knowing if you have a square or angular face shape and are looking for softer frames to balance it.
One further figure: the entire catalogue is designated unisex. Sizing is treated as a function of face measurement rather than gender, which is the more useful basis for choosing, as covered in our piece on whether sunglasses are unisex.
How to use this when buying
Measure a frame you already own and like. The three numbers inside the temple give you your working range instantly, and comparing them against the distributions above tells you whether you sit in the middle of the market or in a tail.
If you are in a tail, filter by measurement rather than browsing. Someone needing under 48 mm lens width is looking at roughly one frame in eight, and browsing by appearance wastes most of that effort.
Prioritise total frame width against your face width. It predicts fit better than lens width alone, because it accounts for bridge and end pieces together.
