Find Your Frame Size

Choosing the right frame size is the first step toward glasses that look great and feel comfortable all day. Whether you’re online shopping for the first time or upgrading your trusted pair, knowing what to measure (and why it matters) makes all the difference.

1. Locate the Size Numbers on Your Current Glasses

If you already own a pair that fits well, you’re halfway there. Check the inside of the temple arm (or sometimes the bridge) for three numbers separated by dashes (e.g., 48-19-140). These numbers relate to: lens width, bridge width, and temple (arm) length.

Here’s how to interpret them:

  • Lens width (e.g., 48 mm) – horizontal size of each lens

  • Bridge width (e.g., 19 mm) – distance across your nose between the lenses

  • Temple length (e.g., 140 mm) – length of each arm from hinge to tip

If your pair doesn’t display size numbers or you don’t yet have a pair, don’t worry—we’ll show you how to measure yourself next.

2. Measure Your Face (or a Well-Fitting Pair)

You’ll need a millimeter ruler or measuring tape and a mirror. Here’s how:

Frame Width

Measure horizontally across the front of your glasses (hinge to hinge). Your frame width should be about the same width as your face—no more than one finger width wider. Warby Parker+1

Bridge Width

Place the ruler between your lenses at the part that sits on your nose. A comfortable bridge fits without slipping, pinching, or creating a gap.

Temple Length

Measure from the hinge of the frame to the tip of the arm (including the bend behind your ear). Typical lengths are 135-150 mm.

Lens Height (Optional, but Very Helpful for Progressives or Tall Frames)

Measure the vertical height of one lens at its tallest point. For progressives, a lens height of at least 30 mm is recommended. 

3. Choose Your Size Based on Fit Categories

We group sizes into broad categories to help you pick quickly:

  • Small – Frame width under ~130 mm / Lens width ~48-50 mm

  • Medium – Width ~130-140 mm / Lens width ~51-54 mm

  • Large – Width above ~140 mm / Lens width ~55 mm+

If your measurement falls between two sizes, go with the wider fit if you prefer looser wear, or the narrower fit if you want a snug, minimal look.

4. Check Fit Beyond Numbers

Numbers help, but fit also comes down to how the frames sit:

  • Your eyes should be centred inside each lens

  • The frame top should follow or sit just below your brow line

  • Temples (arms) should sit flat behind your ears, not "stick out"

  • You should be able to fit one finger between your temple (arm) and your head — any more and the frame may be too loose

These intuitive checks align with how top brands advise customers.

5. What If You’re Buying Online and Don’t Have a Reference Pair?

No problem. Here’s what to do:

  • Select a medium size as a safe starting point

  • Use product filters on our site (by “Size”, “Width”, or “Lens Width”)

  • Compare your face width in a mirror with how frames look on your screen

  • We offer free returns and refunds if you feel that your Frames are not the right fit.
