Size it like a pro
The four numbers that size any frame
You can't perch a pair on your child's nose through a screen โ but fitting kids' glasses online isn't guesswork. Once you know what to look for, you can order with confidence, even for a wiggly four-year-old who won't hold still.
Buddy's quick answer
Match three simple frame measurements โ lens width, bridge width, and temple length โ to your child's age and face, and you'll know a pair fits before it ever arrives.
The numbers
What to measure
Every frame is described by these measurements โ usually printed right inside the arm of a pair that already fits.
Lens width
The width of one lens, about 40โ54mm for kids. The single biggest driver of overall fit.
Bridge
The gap between the lenses that rests on the nose โ too wide slides, too narrow pinches.
Temple length
The arm length, from hinge to behind the ear. Keeps the frame secure without pressure.
Total width
Hinge to hinge across the front โ it should match the width of your child's face.
Start here
Match the frame to their age
Kids' faces change fast, so our frames are built to grow with them across a few broad stages.
Toddlers (1โ4)
Small bridges, soft flexible materials, and often a wraparound strap option to keep frames put during full-speed play.
Little kids (5โ8)
A slightly wider fit with spring hinges that survive being taken on and off a hundred times a day.
Big kids (9โ12)
Closer to a small adult fit, with more style choices as they start caring about how they look.
Teens (13+)
Adult-style proportions with the right bridge width and a stable temple length for full days of school and screens.
Check the fit
The three signs of a good fit
When the glasses arrive, here's how to know they're right.
The frames sit level
Look at your child straight on. The glasses should be even across their face, not sliding down or tilting to one side.
The eyes are centered
Each eye should sit roughly in the middle of each lens, not crammed toward the inner or outer edge.
The arms rest gently
The temple arms should follow the curve to the ear without pinching behind it or leaving a red mark.
