Breaking sunglasses is never fun, except for the part when it’s time to shop for a brand-new pair. But how can you measure sunglasses to ensure the new pair fits just the same as your old pair?

To measure sunglasses, grab a tape measure or ruler. Measure all dimensions in millimeters. Measure lens width and height, as well as the distance between the two lenses. You should also measure the total length of the front of the sunglasses, which should match your temple measurements.

Taking these measurements before purchasing can save time and money, ensuring that the chosen sunglasses meet your needs and preferences. Let’s take a look at how to measure your sunglasses.

How To Measure Sunglasses

To accurately measure the dimensions of sunglasses, you will require several tools, including a ruler, tape measure, and calipers. To measure the sunglasses, follow the steps outlined below:

  • Measure the lens width: Use a ruler or tape measure to measure the horizontal distance across one lens of the sunglasses, from one edge of the frame to the other.

  • Measure the bridge width: This is the distance between the two lenses at the top of the frame, where the nose pad rests. Use a ruler or calipers to measure this distance.

  • Measure the temple length: The length of the arms that rest over the ears. Measure this distance from the hinge at the frame’s end to the temple’s tip.

  • Measure the lens height: Measure the vertical height of one lens from the top to the bottom of the frame.

  • Measure the frame width: Measure the frame width from one end to the other, including any decorative elements.

Note: most sunglasses come with a sizing guide that provides measurements for the lens width, bridge width, and temple length. Compare your measurements with the sizing guide to ensure a proper fit.

It is important to keep in mind that different sunglasses styles may have varying measurements and fit differently. Therefore, it is advisable to try on sunglasses before purchasing to ensure a comfortable fit.

How To Determine The Size Of Your Current Sunglasses 

Locate the model number. The model number of your sunglasses is typically printed on the inside of the arms or the bridge. You can use this number to look up the model number of your sunglasses on the manufacturer’s website. 

The website should have a section that lists the dimensions of each model. Also, note your sunglasses’ lens width, bridge width, and temple length measurements.

Can’t find a model number? That’s okay, you can also measure your sunglasses using a tape measure and the instructions in the next section.

Measure The Dimensions Of Your Sunglasses

Using a ruler or tape measure, measure your sunglasses’ lens width, bridge width, and temple length. It is crucial to measure in millimeters as sunglass sizes are listed in mm. It’s best to write down these measurements as you go so you don’t forget them.

If you have more than one pair of sunglasses, measure the one which fits you better. You can also measure both and see what the small differences are between the two pairs.

How To Measure Your Sunglasses Using a Ruler 

The first measurement is the lens width, which is the distance from one edge of the lens to the other. 

  • This measurement is commonly taken in millimeters, as it is the standard measurement used in the sunglasses industry. 

  • Next, the bridge width must be measured, the distance between the two lenses at the top where the nose pad sits. 

  • The temple length is also important to measure, as it refers to the length of the arms over the ears. This measurement is taken from the hinge to the temple’s tip and should be in millimeters.

  • Additionally, lens height is another essential dimension to consider when measuring sunglasses. 

  • It refers to the distance from the top of the lens to the bottom and should be measured precisely in millimeters. Finally, the frame width must be measured, including any decorative parts.

  • It is recommended to check the sizing information provided by the manufacturer, which commonly includes the lens width, bridge width, and temple length. 

How To Measure Your Temples To Assess Sunglasses Size 

The following steps may be taken to determine the correct sunglasses size for your face. First, obtain a measuring tape and place one end at the midpoint of the forehead, directly above the eyebrows. 

Then, follow the contour of the skull with the tape towards the back of the ear. Record the length in millimeters. Repeat the process for the other side of the head for accuracy. It is important to ensure that the length of the sunglasses matches or slightly exceeds the measured length for optimal comfort. 

Note: Different sunglasses styles may have different fittings, even if the temple length is the same. Therefore, it is advisable to try on sunglasses before purchasing to confirm suitability.

To obtain the lens height, measure the distance between a single lens’s top and bottom edges. Compare your measurements with the sizing details provided by the manufacturer or seller. It is essential to note that different sunglasses styles have varying measurements and may fit differently, so trying them before buying is advisable. 

Following these steps, you can select fashionable sunglasses that provide optimal eye protection and a comfortable fit.

Ordering glasses online requires several measurements to ensure a proper fit successfully:

  • The distance between pupils, known as pupillary distance (PD), is necessary to align the lenses with the eyes correctly.

  • The lens height, measured from the top to the bottom of the lens, and the lens width, measured from one side of the frame to the other, are crucial to ensure that the lens fits the frame and the face.

  • The temple length, measured from the hinge to the end of the earpiece, and the bridge width, measured between the lenses over the nose, are necessary for a comfortable and secure fit.

These measurements can be taken by a professional optometrist or optician or by using a PD ruler and a millimeter ruler at home. It is essential to ensure accurate measurements to avoid discomfort, vision problems, or a poor fit.
