Specs Frame Size Chart: My Simple Breakdown


When I first looked at a specs frame size chart, I was confused by all the numbers and diagrams. Here's how I finally made sense of it all.


The Basic Three Numbers

Every pair of specs has three key measurements printed inside, like "52-18-140":


52 - Lens width in millimeters
18 - Bridge width in millimeters
140 - Temple length in millimeters


Why These Numbers Matter

Each measurement affects fit differently:


Lens width - Determines if frames look proportionate on your face
Bridge width - Affects comfort on your nose
Temple length - Ensures arms reach properly behind ears


How I Use Size Charts

My process is simple:


Find specs I own that fit well
Write down their three numbers
Look for new specs with similar measurements
Stay within 1-2mm of my ideal size


Common Size Ranges

Most specs fall into these categories:


Small: 48-50mm lens width
Medium: 51-54mm lens width
Large: 55mm+ lens width


My Key Takeaway

Once I understood what the numbers mean, size charts became incredibly useful. If you liked this article so you would like to get more info about homepage nicely visit our own website. They're not complicated - just three simple measurements that ensure proper fit.
