Fit perfect.
"Finding shin guards for kids has been difficult, but Century nailed it with the Brave Youth Shin Guards! We ordered a Yth S/M pair for our 7 year old son. He is 47 inches tall and from the floor to bottom of his knee caps is 11 inches. These fit perfect and could probably fit kids a little small than those specs. These are not the super soft thin neoprene shin guards, these are quite a bit thicker and provide the same protection as the adult shin guards that most of our fighters use. Perfectly done Century!"
