When ordering sunglasses online, getting the right lens width is crucial for a comfortable and stylish fit. Here’s a simple step-by-step guide to measuring your face and finding the perfect lens width:
Prepare for Measurement: Find a well-lit area with a mirror and grab a millimeter ruler or a tape measure. If you have an existing pair of sunglasses that fits you well, it can be helpful for comparison.
Measure Your Face Width: Start by measuring the width of your face. Place the millimeter ruler or tape measure across your face, from the top of one cheekbone to the top of the other. Make sure to follow the natural curve of your face, passing just above your nose. Note down this measurement as your face width.
Measure the Bridge Width: Next, measure the width of the bridge of your nose. Place the ruler at the start of one eyebrow arch, just above your nose, and measure across to the same point on the other side. This measurement will give you an idea of how wide the bridge of the sunglasses should be to fit comfortably on your nose.
Calculate Lens Width: To determine the right lens width, subtract the bridge width measurement from your face width. The resulting number will give you an approximate lens width for each eye. For example, if your face width is 140mm, and the bridge width is 20mm, then the lens width would be around 120mm (140mm – 20mm = 120mm).
Consider Face Shape and Style: While the calculated lens width is a good starting point, consider your face shape and personal style when choosing the final lens width. Different face shapes suit different lens widths and styles. For instance, oval faces often look great with a variety of lens widths, while round faces may benefit from more angular frames.
| Face Size (Temple to Temple Measurement) | Lens Width | Arm Length |
|---|---|---|
| Narrow (less than 129mm) | 50mm and under | 135mm – 140mm |
| Medium (130mm – 139mm) | 51mm – 55mm | 140mm – 145mm |
| Wide (over 139mm) | 56mm and above | 150mm or above |
| Nose Bridge Size | Bridge Measurement |
|---|---|
| Small | 14mm – 16mm |
| Medium | 17mm – 19mm |
| Wide | 20mm – 23mm |
