I meant the front. The back might be a little long also.
I usually cut long and then snip off a 1/4" or 1/2" until I get my lengths to what is my experience correct. The general rule is that cables should enter stops squarely and have nice curves without a double curve.
Once I get housing the length I like for a specific bike, I will cut replacement housing the exact same length.
