While not all eyewear comes in varying sizes, many do, and choosing the correct size is crucial for a comfortable fit—particularly with prescription glasses. Measuring your face for glasses is a simple process, and once you have your measurements, you can confidently order without hesitation.

How to Measure Your Face for Glasses
In just three minutes, you can gather all the necessary measurements to buy your glasses. No special tools are needed.
- Step 1. Prepare Your Tools. You only need a few basic items: a flexible measuring tape or ruler and something to record your measurements, such as a pen and paper or your smartphone.
- Step 2. Use a Mirror. For precise measurements, stand in front of a mirror without your glasses. If a mirror isn’t available, use your phone’s selfie mode as an alternative.
- Step 3. Measure Your Pupillary Distance. The pupillary distance (PD), the space between your pupils, is essential for prescription glasses. Use the measuring tape horizontally under your eyes, aligning zero with one pupil’s center and noting the number that aligns with the other pupil’s center. Record this in millimeters.
- Step 4: Take Extra Measurements. Additional measurements, such as face width (temple to temple), bridge width (across your nose), and temple length (temple to ear), can help ensure a better fit. These should also be recorded in millimeters.
- Step 5. Choose Your Size. Input your measurements or consult the brand’s sizing guide to select the right fit. Some brands may require your PD, while others use charts or ask for face width categories like narrow, medium, or wide.
Tips for Selecting the Perfect Glasses Size
Here are a few extra tips to help you find the ideal eyeglass size.
Check Your Existing Glasses
Most eyeglasses feature a set of three numbers separated by dashes, usually printed or engraved on one of the arms. These numbers, measured in millimeters, represent the glasses' dimensions. The first number typically indicates the lens width, the second the bridge width, and the third the temple length. Use these measurements as a guide when selecting your next pair.
Measure Your Old Glasses
If your glasses lack this information or if it has faded, you can measure the glasses directly. Determine the lens width (the horizontal diameter of one lens), the bridge width (the section that rests on your nose), and the temple length (from the front to the end of one arm). Ensure all measurements are in millimeters.
Consider Your Nose Width
For a narrow nose, opt for a smaller bridge width, while a wider nose pairs better with a larger bridge width. This ensures your glasses stay in place comfortably without slipping or feeling too tight.
Consider Your Eye Width
The spacing of your eyes can influence the ideal lens size. While most people fall into the medium range, exceptions exist. Warby Parker suggests using a credit card to gauge your fit: place the long edge against your nose. If the opposite edge extends past your eye’s outer corner, a narrower lens width is ideal. If it doesn’t reach the corner, wider lenses are better. A medium frame works best if it aligns perfectly.
Consult an Optician
If you’re uncertain about your glasses size, visit an optician for professional measurements. Record these details for future reference.
