1. Frame Width

Measures horizontally across the entire front of the frame from one end to another, including any pieces that extend out on the sides. 

2. Frame Height

Refers to the vertical height of the frame measured from the exterior.

3. Lens Height

The vertical height of the lens measured from top to bottom excluding the frame. 

4. Bridge Size

The vertical height of the lens measured from top to bottom excluding the frame. 

5. Lens Width

Goes horizontally across the lens. Measure from inside the frame. 

6. Temple Length

Connect to the front of the frame on either side including the bend. Your temple length can vary between 120 mm and 150 mm. Measure from the start of the hinges in a straight line to the end without sloping downward. 

*This information can be found on the temple of some eyewear.

You may refer to your eyewear to find these details. See picture below.


  • If you already have a pair of glasses, you can compare the measurements to your existing frame. Some glasses may have this information printed on the temples of the frame
  • If the SPH on your prescription is +/-6.00, it is recommended to select frames with lens widths lower than 50 mm. This will keep your lenses thinner.

Measure your PD (Pupillary Distance)

As the name suggests, pupillary distance is the distance between the center of your pupils. PD measurement indicates the optical center of the eyes and is used to determine where the eyes focus through the lens of the glasses. 

You might have this information on your prescription from your previous eye check. Don’t fret if you don’t, you can measure it yourself in a few simple steps and save the hassle of running to your local optical store.
