How to Measure Eyeglasses Size?

Before you head to your nearest eyewear store or start browsing online, it's crucial to know the correct way to measure eyeglasses size. Follow these simple steps to get accurate measurements and ensure a comfortable fit for your frames:

Measure Your Pupillary Distance (PD)

The pupillary distance (PD) is the distance between the centers of your pupils and plays a significant role in how well you see through your lenses. To measure your PD, follow these steps:

Stand in front of a mirror with a ruler or PD measurement tool.

Hold the ruler against your brow, aligning it with your right pupil's center.

Look straight ahead and note the measurement at the center of your left pupil.

Determine Frame Width

The frame width is crucial for ensuring that the eyeglasses fit your face comfortably. Measure the width of your current glasses or use a ruler to measure from the outer edge of one frame to the other.

Measure Lens Width

To measure the lens width, use a ruler to measure the widest part of one lens horizontally.

Measure Temple Arm Length

The temple arm length is the part that extends from the frame to the back of your ear. Measure it from the temple's hinge to the end of the arm.

Check the Bridge Width

The bridge width is the space between the lenses and plays a vital role in keeping your glasses stable on your nose. Measure it using a ruler from one lens's inner edge to the other.
