It might be better not to count the spaces, but the characters, which will be a better guess for the actual line length. You can wrap any string to a specified minimum and maximum chars per line (here:{3,30}) with that regex:

$_ = 'School of Wisdom and Knowledge College Preparatory';
s/(.{3,30})\s+(.+?)/$1\n$2/g;
print;
