The Almost Foolproof Way to Determine The Frame Size of Your Readers

If you’ve ever ordered readers and thought, hope I picked the right size, this guide will simplify your decision making.

We categorize our readers by average face sizes, small/petite, medium/average, and large/oversized- based on typical male and female head measurements. But for the most precise fit, here’s how to determine your best size.

Every optical frame has three measurements printed on the inside of the temple arm (and listed on our style pages):

Lens width – Bridge size – Temple length

Lens width is the most used reference, but it’s not the only factor that affects fits. Bridge width, frame thickness, and end piece design all play a role in how a frame actually fits on your face.

For non‑prescription eyewear like reading glasses, total frame width is the most reliable measurement for your best fit.

Total frame width is measured in millimeters from the outer edge of one side of the frame to the outer edge of the other. This measurement should be slightly wider than the widest part of your face for a secure, comfortable fit.

How to Measure Your Frame Size

• Stand facing forward in front of a mirror.
• Hold a ruler horizontally just below your eyes.
• Measure temple‑to‑temple in millimeters.
• Use this measurement as your guide when choosing readers.

Styling a Look Based on Frame Width

·         Classic Fit Style Relevant: Choose reading glasses proportionate to your face and stature. A slightly larger frame can still give off classic vibes, while leaning trend forward.

·         Fashion‑Forward Fit: Intentional small or oversized looks push boundaries- just check the frame width so the fit wears comfortably all day. An adjustment to the temple will reduce slippage.

·         Oversized Frames: Larger, more structural frames often soften facial features and, by sheer contrast, complement fuller faces. Their generous lens size has earned a loyal following for digital readers,  delivering a wide, seamless viewing area.

·         Balancing Fuller Features: Frames that extend beyond the widest part of your face add visual balance and a proportionate, good fit . When temples press into your face or fail to wrap comfortably around your ears, long wear becomes uncomfortable and the fit unstable.

·         Small Frames: Small‑scale frames add a stylish edginess, often artful or vintage. Ours feature longer temples so they fit securely on average‑size heads.

Styling a Look Based on Frame Depth

Frames designed for fashion looks or digital use often feature not only wider lenses but larger, deeper lenses -technically called the B measurement.

Visual Benefits:

·         An expanded field of view for screens so you can see your entire monitor with less head movement.

·         More protection for your eyes and surrounding skin — essential for high screen‑time lifestyles.

Choosing best fitting readers is easy when you understand how frame measurements relate to your own. Using total frame width as your guide makes determining your frame size almost foolproof.  Your readers won’t just fit, they’ll feel natural, flatter your features, and wear comfortably all day.
