How to Measure for a Pair of Glasses at Home

When thinking about measuring a face for frames, you first need to consider the many parts that glasses have. Because of this, glasses don't just come in large or small sizes. Instead, the size depends on measurements such as frame width, bridge width, and arm length.

To do this at home, you’ll need a mirror and a ruler. Find a ruler that measures in centimeters or millimeters, as glasses are always measured in millimeters.

Frame Width

Frame width is the most straightforward aspect and is determined by measuring the distance between your temples. To find your frame measurement, hold the ruler horizontally across your face and just below your eyes. You’ll then get your temple measurement by noting the distance between your left and right temples.

Bridge Width

Bridge width refers to the width of the space between the lenses, or where the glasses rest on your nose. Your bridge measurement is important, as it can be quite frustrating to have a pair of eyeglasses that slide down the bridge of your nose.

It is dependent on the size and position of the bridge of your nose. Use a mirror and ruler to measure your bridge width. Be sure to also note the shape and placement of your bridge when measuring, as it can help you find the right frames fit for your face.

Remember that the bridge measurement may change depending on the frame material; thicker frames will have more space between lenses, so the bridge width will be greater.

Arm Length

Arm length ensures that your glasses will fit comfortably over your ears. If you have a longer temple, you'll want a longer arm length. Those with smaller temples will need a pair of eyeglasses with a shorter arm length.

Face Shape

You also need to consider your face shape when selecting frames, as different types of frames look best on different face shapes. For instance, a square-shaped face often matches well with circular or oval frames, while more rectangular frames tend to be more flattering on people with round faces.

If this sounds like a lot, don't worry. The staff at your local eye doctor is specially trained to help fit you for glasses, saving you additional work and headaches.

After an eye doctor examines your eye health and writes a prescription for eyeglasses, an optician can help you find the glasses that best fit you. They're well-versed in the various frames, coatings, and other options available. You can learn about the different types of glasses online, but it's easy to miss important information that could have helped you get better frames or lenses. When you go in person to an eye provider's office, you can relax and let the optician or other trained team members guide you through the fitting and selection process.

Should You Measure Eyeglasses Yourself or Visit Your Eye Doctor?

While it is possible to measure yourself for glasses, you can't guarantee the quality of a frame you fit for yourself. Seeing a professional is the most reliable way to find the glasses that are right for you.

Some eyeglass prescriptions require precise measurements by an eye doctor, such as progressive lenses. These lenses correct for distance on the top half and reading on the bottom half, transitioning gradually between the two throughout the lens. Progressive lenses need precise measurements that are best done in person.

Additionally, you will probably find yourself happier with glasses that are purchased in person from an eye care provider versus ones that you fit yourself for at home. A 2016 study in Optometry and Vision Science found that customers were overall happier with glasses purchased through an eye care provider versus ones that they bought online and fit for themselves. Some study participants even said that eyeglasses purchased online were unacceptable or unsafe because of poor frame fit.
