How to Know What Size Glasses I Need: What I Learned
For the longest time, I had no idea how to know what size glasses I need. I’d just try on random frames and hope something worked. If you liked this article and you simply would like to get more info about website generously visit our web-site. After years of ill-fitting glasses, I finally figured out a systematic approach.
Start With What You Already Have
The easiest way to determine your size is to check glasses you already own that fit well. Look on the inside of the temple arm – you’ll see three numbers like “52-18-140”. Write these down. These are your baseline measurements.
If you don’t have glasses yet, don’t worry. You can measure your face directly.
Measuring Your Face for Glasses
Here’s the method I use:
- Face width – Measure from cheekbone to cheekbone (mine is 143mm)
- Nose bridge – Measure across the bridge of your nose (I need 18mm minimum)
- Temple to ear – Measure from your temple to behind your ear (about 145mm for me)
These measurements tell you what frame dimensions to look for.
Understanding Size Categories
Most glasses fall into size categories:
- Small – Lens width 48-50mm, total width under 130mm
- Medium – Lens width 51-54mm, total width 130-140mm
- Large – Lens width 55mm+, total width over 140mm
I fall into the large category, which immediately narrows down my options when shopping.
The Try-On Test
Even with measurements, I always do a fit check:
- Frames shouldn’t extend past my face width
- Eyes should be centered in the lenses
- No pressure points on temples or nose
- Frames stay put when I move my head
What I Wish I’d Known Earlier
The biggest lesson? Don’t guess. Take five minutes to measure properly, and you’ll save yourself from countless returns and uncomfortable frames. Knowing your size makes shopping for glasses actually enjoyable instead of frustrating.
