How to Size your Sunglasses

Beside trying on a bunch of shades, there are some better approaches on how to find glasses that fit your face. These tips really work for any glasses you need, and they can assist you with making sense of what style will look best with your shape and size. Shades will in general are bigger than eyeglasses, however the estimations are determined in a similar way. 

Start With Your Head

With the end goal of finding stylish eyewear, you will need an exact measurement of your head size. That way, you'll have a reference point for what size shades you need. This will also enable you to find out what glasses are too large, and what frames looks best for your face.

Saying that you have a "small head" or a "big face" is helpful for you to know, yet it doesn't help if you when you are doing online shopping . Sunglass shopping should be fun, easy, and quick!

How To Get The Millimeters

When estimating your face, you'll have to line up a ruler (on the millimeter side) by your temple. The ruler shouldn't fold over your head, rather, it should glide before your face in the space where your temple is found. At that point, measure straight crosswise over to the next temple. The estimate you get is the best frame size for your face.


Eyewear Measurements

Glasses have three primary sizes you need to know about.

Eye size is the width of the lenses at the widest part. It’s the most common measurement you’ll see in reference to the size of glasses. Ray-Ban New Wayfarer Sunglasses come in 52 mm and 55 mm lens sizes.

Bridge size measures the piece of metal or plastic that connects the lenses. In order to measure the bridge, you start and end at the innermost side of the lenses and measure to the same spot on the other side of the bridge.

Temple size is the measurement of the arms of the sunglasses. Also called the temples, the measurement of the arms starts at the hinges and continues in a straight line to the farthest point without sloping downward.

Vertical measurement tells you how tall your glasses are. This doesn’t always help unless you’re ordering prescription sunglasses that require special lenses but regardless, it is measured from the bottommost part of the lens straight up to the top.

Your Width Versus Theirs

General width will tell you how large the glasses are in total. You can then measure your face and see how many millimeters across it is to get a rough idea of how large the glasses will be. To figure this part out, measure the segments of the temples you can see from the front along with the lenses and bridge. That number will tell you roughly if the glasses are large enough for your face.

Estimate Your Match Up

If you know the total width of the sunglasses (including lenses, end pieces and bridge), you can in general, subtract 6 mm from the total and compare it to the width you calculated earlier. If it’s within 2 mm of your face size, they should be a good fit for you. If you don’t have the total width but you have the glasses to measure, add up the lenses multiplied by two with the bridge size. If that number is within 2 mm of your face size, you should be good to go with those glasses as well.

Get Ready! Get Tape!

Measuring your face sounds tedious, but it will make the process of buying and returning sunglasses much less hassle. Without the measurements, it’s really hard to tell if glasses have the right sized bridge or lenses to fit your face. It only takes a few seconds, but numbers can clarify a whole lot for you.
