There are very few 11 & 12 year olds who are not over the booster sest height and weight.
Most of my fourth graders' friends are either at or above the max weight and height. My kid is still short enough for a booster in fourth and very likely fifth, but his friends are all close to five feet tall with many if not most of them over or around 80 lbs.
