These pads fit a 4-yr-old, a 6-year-old, and would fit older kids just fine. My kids were wearing them over snow pants, so the bands are nice and stretchy while staying in place. They are awesome because they are big! They actually cover the entire elbow and knee area and stay in place. The kids fell a lot and the plastic scratched up pretty easily, but the kids didn't even cry! Excellent padding and can be worn by all ages of kids (I would assume starting at age 4...younger than that might be too skinny).
