Of course, all kids have different head sizes but we have tried our best to give general guidelines for the sizes of glasses we offer. If between sizes, sunglasses can probably be interchangeable for most children.We have also tried to include measurements of most glasses in the descriptions and according to the chart below.
Little Kid Sunglasses: size 6 months-3 years
Big Kid Sunglasses: size 4 years-10 years
For babies and toddlers, we offer ear adjusters and strap to help keep the sunglasses in place and keep little hands from pulling them off!
