How they
should sit.
Last updated 2 August 2026
Eyewear sizing is three numbers, usually printed inside a temple: lens width, bridge width and temple length, in millimetres. Below are ours, and a way to work out yours without a tape measure.
The measurements
| Frame | Lens width | Bridge | Temple | Lens height | Total width |
|---|---|---|---|---|---|
| The Square | 52.8 mm | 19.6 mm | 156 mm | 37.0 mm | 140.8 mm |
| The Aviator | 56.3 mm | 17.7 mm | 156.5 mm | 49.15 mm | 144.8 mm |
Both are built to a tenth of a millimetre against their drawing. A frame that drifts further than that does not leave the bench.
Finding your size without measuring
Take a pair you already own and read the numbers inside the left temple — they look like 52□19 145. Compare the first two with the table above. Within 2 mm on lens width and 1 mm on bridge and the fit will feel familiar.
If you have nothing to compare against, email hello@paulsagoo.com with a straight-on photograph and we will tell you which of the two sits better on your face.
Which frame suits which face
- Rounder or softer features. The Square. Its straight brow and chamfered corners give a face definition it does not otherwise have.
- Squarer or more angular features. The Aviator. The teardrop lens softens a strong jaw and a straight brow line.
- Narrow face, under about 130 mm temple to temple. The Square, which is the narrower of the two overall.
- Wide-set eyes. The Aviator’s narrower 17.7 mm bridge brings the lenses closer together.
If it still is not right
Bring it back. Reshaping and refitting are free for the life of the piece under the lifetime repair undertaking, and the thirty-day return applies regardless.
