Eyeglass frame sizing guide: Finding the perfect fit
Finding the perfect look can be as simple as finding the perfect size. Now, of course, there are other factors to consider like frame shape, style and colour. But you’d be surprised at the styles you can pull off when you find a pair of glasses that fit well.
Understanding frame sizing is quite simple and can make shopping for glasses that much easier. This guide will walk you through everything you need to know about eyeglass frame sizing and provide some helpful tips to keep in mind the next time you’re shopping for your next pair of eyewear.
First, Your Frame Size
The best place to start, if you already have an existing pair of glasses, is to determine the size of the frames you already have.
If it’s your first time getting prescription eyeglasses, that’s okay you can skip this part and continue to the next section.
Examine Your Eyeglass Frames
Take a look at your frames and search for three numbers printed or stamped on your eyeglasses.
The locations can vary depending on the manufacturer but they’re usually on the inside of the temple (arm) or on the inside of the bridge of the frames.
From left to right these measurements indicate:
- Lens Width/Eye Size
- Bridge Width
- Temple/Arm Length
Once you’ve identified these measurements, take a moment to think about how your current pair of eyeglasses is fitting.
Do they look too wide or narrow for your face? Do your glasses slide down your nose a lot when you’re wearing them? Are the temple/arms too short or too long?
Doing this exercise will help you build a baseline in finding the best fit for your next pair of glasses.
If you like how they’re fitting then simply look for frames that have similar frame dimensions. If you are not fully satisfied with how they are fitting then take note of what’s not working.
You can use this information the next time you’re shopping for eyewear and look for sizes that are either larger or smaller depending on how your old pair of glasses felt.
Eyeglass Frame Dimensions
Overall Width
Range:110mm - 140+mm
The overall width of the frame will not be printed on the glasses. Unfortunately, most eyewear manufacturers will not provide this information and you will have to measure them yourself.
This measurement spans the entire width of the frame from temple to temple, including any hinges or temple design features that stick out on the side.
At Eye Hub we want to make shopping for prescription eyewear easier than it should be. We have taken the time to provide these measurements for every pair of eyeglasses and sunglasses in our inventory.
We even took it a step further and created a sizing guide for men and women for added simplicity. Once you have determined the best overall frame width for your face you can filter your selections by frame width.
Eyehub Frame Sizing
TIP:
Narrow frames can make your face look wider than it is, and conversely, wide frames can make your face look narrow.
Find eyeglass frames that are slightly wider than your face. Generally, you want no more than a finger width between the frames temple and the side of your face.
Lens Width xx-xx-xx
Size Range: 40mm - 60mm
The lens width is the horizontal width of each lens measured from its widest points.
Bridge xx-xx-xx
Size Range: 14mm - 24 mm
The bridge is the length between the two lenses of the frame. Typically this space is where your glasses are going to be resting on your nose.
TIP:
If your glasses are prone to sliding down or you’re glasses are positioned too high, you may have a bridge fit issue.
Glasses sliding down
Take a look in the mirror, or have a friend look at you with your glasses on. If there is a gap between your frame (frames without adjustable nose pads) and your nose, and they are sliding down you may have frames with too wide of a bridge or you have a low nose bridge.
You can find a better fit for your next glasses with a few options:
- Find a narrow bridge for a better fit
- Look for a low bridge frame
- Get eyeglass frames with adjustable nose pads
At Eye Hub Warehouse we have identified all of our low-bridge frames and you can easily filter your selections by clicking the filter options while you’re shopping
Glasses too high on your face
Take a look in the mirror, or have a friend look at you with your glasses on. If your eyes are positioned too high within the lens or the frames feel tight around your nose then your frame bridge is too narrow.
You can find a better fit for your next glasses with a few options:
- Find a wider bridge for a better fit
- Get eyeglass frames with adjustable nose pads
Temple Length xx-xx-xxx
Size Range: 120mm - 150mm
The temple (arm) length is the entire length of the “arm” that rests on your ears. The measurement spans from the joint to where the temple is connected to the frame all the way to the tip that “hooks” around your ears.
TIP:
Your glasses’ temple (arm) should fit comfortably along the outside of your ear. A short temple can make your glasses feel like they’re about to fall off your face.
A long temple will extend too far past your ears causing the tips flaring from behind or a pronounced “hook” around your ears.
Lens Height
The lens height is the vertical height of each lens measured from its widest points. This measurement cannot be found on the frames.
TIP:
When your eyeglass frames fit perfectly, your eyes should be close to centred within the lenses of your frames. Your pupil should be close to the centre laterally and vertically within the lens.
This doesn’t mean that you should aim for your eyes to be dead centre within the lens but you want to be within range.
Use your best judgement. You should be able to identify if there is something off with the fit when you see them sitting on your face.
Glasses that are too wide will make your eyes look too close together and glasses that are too narrow will make your eyes look too far apart.
