Use the size chart below as a starting point to find the right eyewear size based on your child’s age and lens width.
Lens width is the most accurate way to determine size. Age can be a helpful guide, but fit may vary depending on your child’s face shape, growth, pupillary distance (PD), and frame design.
If your child already wears glasses, you can use their current lens width. If not, you can estimate size using age or face measurements in the chart below.

Measure Your Child’s Current Glasses
If your child already wears glasses, you can measure their current frames to help determine the right size using these steps:
1
Measure the lens widthUse a ruler to measure the width of one lens on your child’s current glasses.
2
Find the closest sizeMatch the measurement to the closest lens width in our size chart.
3
Use age as a guideIf you’re unsure, the size suggested for your child’s age group can be a helpful starting point. Keep in mind that age-based sizing isn’t always exact, as children’s facial features and growth can vary.
No Glasses Yet? Measure Your Child’s Face
If your child doesn’t already wear glasses, you can estimate their size using these steps:
1
Measure face widthUse a ruler or measuring tape in millimeters (mm). Measure across your child’s face from temple to temple (just above the ears). Keep the ruler straight and level for a more accurate result.
2
Find the closest sizeUse the face width measurement to guide you toward the closest size in our chart. Smaller measurements usually align with smaller frames, and larger measurements with larger frames.
Reminder:
These steps will help you find a frame that should fit well, but face shapes vary, so results should be used as a guide rather than a strict rule.
