What Frame Size Glasses Do I Need? A Sizing Guide For Perfect Eyewear Measurements [Updated On 2024]

To find your ideal glasses frame size, measure your face for temple-to-temple width: Narrow (under 129mm), Medium (130mm-139mm), and Wide (over 139mm). Lens widths are: Narrow (50mm and under), Medium (51mm-55mm), Wide (56mm and up). Arm lengths generally range from 135mm to over 150mm.

Next, measure your nose bridge. This is the distance between your eyes and the space your nose occupies. A properly fitting pair of glasses will sit comfortably without pinching or slipping. Lastly, measure the distance from the bridge of your nose to your ears. This measurement ensures that the temple arms of the glasses fit well and do not cause discomfort.

Most glasses have a size printed on the inside of the temple arm. It usually consists of three numbers. The first number indicates the lens width, the second represents the bridge width, and the third shows the temple length. Knowing this information allows you to choose frames that suit your facial structure and personal style.

With these measurements in hand, you can explore frame styles that complement your features, ensuring both comfort and aesthetic appeal. Next, we will examine various frame shapes and how they align with different face shapes for optimal selection.
