The size of a middle school size basketball is 19.5 diameter.
The size of a middle school basketball is 29.5 inches.
I play middle school soccer, and the size for the soccer balls range from size 4 to size 5.
For Middle school and up, all the way to the major league you should use a 12. 75 inch glove.
If its summer league it doesn't matter but if its high school all I know is that you need a bbcor certified -3 bat
highschool track is the same size as middle
it is 400m
It is dependent upon the school and particularly the size/population of the school. Some elementary schools have lockers as well as middle and high schools.
It depends on the track size. Middle school tracks are commonly half the size of "normal" high school tracks. 800m is either 4 laps on a middle school size track or 2 laps on a high school size track. 1600m is either 8 or 4.
Im guessing size 5.
