How to Check the Size of Your Child’s Glasses Frames

If your child is already wearing glasses, you might be wondering how to find the correct size when buying a new pair. Fortunately, the size information you need is usually printed right on the inside of the current eyeglass frames.

Where to Find Frame Size on Glasses

Most children’s glasses frames come with size markings printed on the inner side of the temples (arms) or the bridge of the nose. These numbers typically follow a format like:
"52□18-135"
Here’s what they mean:

· Lens Width (52mm): The horizontal width of one lens.

· Bridge Width (18mm): The distance between the two lenses.

· Temple Length (135mm): The length of the arms that go over the ears.

These measurements are essential when shopping for the right frame size online or in-store. If the size information is worn off or unclear, you can use a millimeter ruler or ask your optician to measure the frame for you.

Why Frame Size Matters for Kids

Proper frame size ensures:

· Comfortable fit without slipping or pinching

· Correct lens alignment for clear vision

· Better durability and stability during daily activities

Helpful Tips When Buying Children’s Glasses

· Stick to the current measurements unless advised by an optician.

· Consider flexible, lightweight materials for active kids.

· Check for adjustable nose pads or spring hinges for added comfort.
