for the length put the bat by your side, stand straight, your wrist should go just below know knobby thing on the end at the end of the handle.(sorry don’t know what the proper term is)
for the weight-try swinging it its usually all about the balance I like my bat to be almost equal weight between the barrel and the handle. It will probably be closer to the barrel.

Are you already playing on a team? If so, start off by using one of your teammates bats until you find something that you like. No point in spending a couple hundy on a bat if you don’t know if you’ll like it, or not. Some bats are “classified” as the same weight (ie: 28 oz) but the weight is proportioned differently on the bat. One bat may feel like the weight is on the end of the bat, where another may feel like the weight is closer to the handle. It’s ll in what you prefer and what feels good for YOU.

umm nike doesn’t make bats but see i play fastpitch so let me give it a go! I suggest the Catalyst XL. I get a new one every year. Right now I have 3 it’s a comp. bat around $2.80. Not bad for a good bat. Oh and it is approved by all major organizations such as ASA,NCA, & AAU

They have to be different because the balls are different. Just like softball gloves are different from baseball gloves.

it all depends and your arm strength. Don’t use a larger bat than you can swing compfortable, however, u want to use a large of a bat as you get without sacrificing a significant amount of bat speed. Hope this helped

Well I would have to say in my opinion and on value I play ASA fastpitch softball, I think the “Minzuno Jennie Finch Bats” are the best!!
That the only kind of bat I use they are pretty good price from 80-170$ .
Really good bats!
They are hard to get though they sell out quick.

try the synergy those r great for fast and slow the best bat out there. i have the 2008 fast pitch abt. an it gots pop!!! hope this helps.

Find a bat that give you the best bat speed and the tallest bat

I would think given the different sizes of the balls and the speeds that they travel to the bat, there is a major risk of the bats breaking if used in the alternate game they were designed for

30, 31,32 inchs is a good size
