Reading the Frame sizes: The numbers

Eyeglass frame sizes are indicated by three numbers stamped on the inside of your eyeglasses. These numbers usually appear on the inner surface of one of the frame temples that hold your glasses in place behind your ears. The measurements that describe eyeglass sizes are the eye size, bridge width, and temple length.

Lens Width

The first number refers to the eye size, that is, the horizontal width of the lenses. Generally, the lens width of most frames will be 44 to 62 mm.

Bridge Width

The bridge width is the essential part to consider when choosing a frame. The bridge's design should be conducive to comfort and assistance, which ensures your eyes are in a natural gaze state and the position of the lens is correct.

Temple Length

Temple length refers to the total distance from the beginning of the temple to the end of the temple. It consists of two parts: the length of the drop and the length to bend.

Frame Width

Another measurement to consider is the width of the frame. It is worth noting that the total width of the frame can be calculated by the following method: the lens width × 2, plus the width of the bridge, plus approximately 7mm on each side. Keep in mind that there may be deviations due to factors such as product style and design.

How to choose the correct size glasses

If you wear glasses, you may notice some numbers on the temples or bridge of the eyeglass. These numbers usually include information such as the frame model, color code, and frame measurements.


Step1 Finding Your Frame Measurements

Frames on websites are often filtered, among other categories, by size: Small (sometimes indicated by an S), Medium (M) and Large (L). The vast majority of glasses display the measurements somewhere on the frame. More often than not you’ll find these numbers on the inside of the temple arms.

Before choosing a new frame, you can obtain the measurement value of the frame that suits you by looking at the old frame (usually at the temple or the bridge), for example, 52-16-135:

  • 52 (mm) represents the width of the lens
  • 16(mm) represents the width of the bridge
  • 52 (mm) represents the total length of the temples

In order (from left to right), the numbers will refer to your current glasses lens width, followed by bridge width and the length of your temple.

Step2 Finding Your Frame Size

If you have your frame measurements, finding out your frame size is super simple. Each eyeglass shop has a corresponding frame size chart. You can also consult customer service and try on the glasses yourself before knowing whether the glasses fit.

Opticians are trained to help you choose the correct eyeglass sizes. Sometimes, even the right size eyeglasses need additional adjustment. If you have any questions, please consult a professional optician.

More Tips

Generally, the best eyeglass sizes will result in the following fitting characteristics:

  1. The weight of the frame is evenly distributed across the bridge of your nose.
  2. The frame temples gently touch the sides of your head without any significant pressure or a large gap between the frame and your head.
  3. The temples are long enough to extend beyond your ears so the ends can be adjusted to conform to the contour of your head for a secure, comfortable fit.
  4. You should be able to bend forward, look straight down at the floor, and shake your head without your glasses slipping or sliding out.
