It all depends on what lock you want it for, generally you would have them both the same height to get this height start off by making them so it just fits in the keyhole, have a go useing it and you will soon work out if you need to take a little more off, the best way is to look at either the key blank for that lock or open the lock and work it out, the longer the better in my view but ive had no real instruction on this myself only home made ones,
If it fits in the key hole it should be ok, dont force anything whilst picking or they could break.
