Well normally around 4 inches but if you want a good deal if you are looking for a stick that is junior length you can buy the youth stick and 1 end plug and shove it in the back of the youth stick. But only in a composite hockey stick. Also normally a youth hockey stick can be about 50 dollars cheaper ten the junior. The end plugs are about 5 to 7 dollars. good luck
