Frame measurements made simple: lens width, bridge, and temple length

Frame measurements made simple: lens width, bridge, and temple length

Best for: you want to use frame size numbers instead of guessing from photos alone.

Most glasses list three main numbers: lens width, bridge width, and temple length. They are usually printed inside the temple arm. These numbers do not describe everything, but they give you a practical way to compare one frame to another.

Quick fit notes

Lens width affects both look and lens thickness

Lens width is the horizontal width of one lens. Wider lenses can feel more fashion-forward, but they may also show more lens edge thickness with stronger prescriptions. Narrower lenses often feel cleaner for petite faces and higher prescriptions.

Bridge width affects stability

The bridge is the part that sits over your nose. A bridge that is too wide can slide; a bridge that is too narrow can pinch. Adjustable nose pads can help because they offer more room for fine tuning.

Temple length affects behind-the-ear comfort

Temple length is the arm length. If it is too short, the frame can pull forward; if too long, it may feel loose. Use our help center if you need help comparing measurements before ordering.

At-a-glance guide

Measurement What it describes Why shoppers care
Lens width Width of one lens Affects face proportion and lens edge thickness
Bridge Distance over the nose Affects sliding, height, and comfort
Temple length Arm length to ear Affects grip and behind-ear comfort
Frame width Total front width Helps judge narrow, medium, or wide fit
If you own a pair that fits well, write down its numbers. It is the easiest reference point for online shopping. Read the reference.

Where to start on Framelune

If you are comparing styles, open women's eyeglasses, best sellers, and new arrivals in separate tabs. Save two or three frames that feel natural with your face, then narrow the choice by bridge comfort, frame width, and lens needs.

For prescription orders, take a minute to review your SPH, CYL, AXIS, ADD, and PD values before checkout. If anything looks unclear, use the help center or contact Framelune before placing the order.
