How to Measure Your Eyeglass Frames Size: A Guide

Are you tired of constantly having to adjust your eyeglasses? Finding the right frame size for your eyeglasses is essential to looking and feeling your best. Measuring your eyeglass frame size is an important step in finding the perfect pair of glasses. But many people don’t know how to measure their frames. As a result, they end up with uncomfortable and unattractive glasses. Here, we will walk you through the process of measuring your eyeglass frame size and provide some tips for finding the perfect fit.

Different Types of Eyeglass Frames

You can find many different types of eyeglass frames on the market. The most popular type is the full-frame, which covers the entire lens. These are great for people who want to keep their glasses on all the time or for those who have a strong prescription.

Half-frames only cover half of the lens and are perfect for people with milder vision problems or for those who want to be able to take their glasses off more easily.

Rimless frames have no metal or plastic around the lens, making them very light and comfortable to wear. They’re also less likely to slip down your nose. Clip-on frames attach to your regular glasses and can be flipped up or down depending on whether you need them.

Measuring Your Eyeglass Frames

Inspect the temples (arms) of your eyewear; you’ll find some measurements. Don’t be concerned if you can’t find any numbers or specifications on your eyeglasses. You can measure the dimensions of your frame with a millimetre ruler. Consider the following for measuring your eyeglass frames:

  • Lens Width
  • Bridge Width
  • Temple Length
  • Lens Height
  • Frame width

Lens width

The horizontal diameter of the lens at its widest point is referred to as the lens width. It is typically expressed in millimeters. This is an important measurement to take, as it will ensure that the lenses will fit properly in the frames. To measure the lens width of your eyeglass frames, use a ruler or measuring tape to measure from the outside edge of one hinge to the outside edge of the other hinge.

Bridge width

The bridge of your glasses is the part that rests on your nose. An ill-fitting bridge can be uncomfortable and cause your glasses to slip down your nose. You can measure the size of your bridge by holding a ruler or measuring tape up to your nose and aligning it with the centre of your pupils. The measurement you get is the width of your bridge in millimeters. Most frames will have a range of sizes for the width of their bridges, so you’ll have to choose one that has a bridge size that’s close to yours.

Temple length

There are two main components to the frame size measurement: the temple arms and the lens width. Start by holding the ruler or measuring tape up to your temples, just above your earlobes, and note down the measurement in inches or centimeters. This is your temple arm’s length.

Lens height

The lens height is the vertical distance between the top of the lens and the bottom of the lens. This measurement determines the size of the frame that will best fit your face.

The average lens height for men is 40–60 millimeters. The average lens height for women is 32–38 mm. If you have a small face, you may want to choose a frame with a smaller lens height. If you have a large face, you may want to choose a frame with a larger lens height.

Frame width

Size matters most when choosing the right eyeglass frames. The frame width is important to consider when picking out your new glasses. Start by measuring the width of your face from temple to temple. This will give you a good starting point for finding the right frame width. Take a look at the width of your lenses. Make sure that the lenses are not too wide or too narrow for your eyes. Finally, try on a few different pairs of glasses and see how they look on your face. Pay attention to how the frames sit on your nose and ears, and make sure that they’re comfortable to wear.

Tips for Choosing the Right Eyeglass Frames

  • Measure your face. You can do this by measuring the distance between your eyes, the width of your jaw, and the length of your nose. This will help you narrow down your frame choices to those that will fit your face well.
  • Choose a frame shape that complements your face shape. For example, if you have a round face, you might want to try oval or rectangular frames. If you have an oval face, you can pretty much wear any type of frame.
  • Consider your lifestyle when choosing frames. If you’re active, you’ll want frames that are durable and won’t slip off your face when you’re sweating. If you wear glasses for work, you might want something that looks more professional. And if you wear glasses for fashion, there are endless options to choose from!
  • Don’t forget about functionality. Make sure the frames you choose will work well with the type of lenses you need (bifocals, progressives, etc.). And make sure they’ll be comfortable to wear all day long.
