How to Find the Right Sunglasses Size
Most people only figure out their sunglasses size after ordering the wrong pair and going through the return process - 8 to 10 days wasted. This guide cuts through all of that.

01 - The three key measurements
Every pair of sunglasses has three measurements printed on the temple arm (e.g. 55-15-120). Here is what each one means:
| Measurement | Small | Medium | Large |
|---|---|---|---|
| Lens Width | 55mm and below | 55 to 58mm | 59 to 62mm |
| Bridge Length | 16 to 17mm | 18 to 19mm | 20 to 23mm |
| Temple Length | 130 to 135mm | 136 to 140mm | 141 to 150mm |
How to read the number
The format is: lens width - bridge length - temple length. So 55-15-120 means 55mm lens, 15mm bridge, 120mm temples.
02The Credit Card Trick
A standard credit card is 55mm in height - the same as a small lens width. Stand in front of a mirror and place one end at the middle of your nose:
- Card extends past the edge of your eye - choose small
- Card reaches just to the edge of your eye - choose medium
- Card falls short of the edge of your eye - choose large
03Use Your Existing Sunglasses
If you already own a pair, check the temple arm. The numbers printed there tell you your lens width, bridge length, and temple length. If they fit well, use those numbers as your reference for any new purchase.
04Consider Your Face Shape
Size is only half the equation. A perfectly sized pair in the wrong shape can still look off.
For detailed recommendations read our complete face shape guide.
- Round face - rectangular and square frames add structure
- Square face - round and oval frames soften strong angles
- Oval face - most frame shapes work well
- Heart face - aviators and round frames balance a wider forehead
- Diamond face - cat-eye and oval frames highlight cheekbones
- Oblong face - wide oversized frames add width

Frequently asked questions
Q1 How do I find the right sunglasses size?
Measure using the three numbers printed on the temple arm - lens width, bridge length, and temple length. Or use the credit card trick: a standard card is 55mm, the same as a small lens width. Place it at the centre of your nose to gauge your size.
Q2 What do the numbers on sunglasses mean?
The three numbers printed on the temple arm are lens width, bridge length, and temple length in millimetres. For example, 55-15-120 means 55mm lens, 15mm bridge, 120mm temples.
Q3 What size sunglasses suit a round face?
Rectangular and square frames add structure and make a round face appear slimmer and longer. Avoid round or oval frames which echo the face shape.
Q4 Can I use my existing sunglasses to find my size?
Yes - check the temple arm of a pair that fits well. The three numbers printed there give you your exact lens width, bridge length, and temple length.
Q5 What size sunglasses suit a square face?
Round and oval frames soften the strong angular features of a square face. Avoid square or rectangular frames which mirror the jawline.
