The default jump height is pretty feeble IMO, and without Acrobatics in Skyrim, I've resorted to a mod. This mod will make your character jump higher. I've included 7 different files, each with increasingly higher jump height. Pick whichever suits your needs. The base jump value is 76 (default). I've included 100, 130, 175, 225, 300, 500, 1000 files. I find 130 to be a decent value. The 500 and 1000 will cause falling injury, and may result in some weird behavior, such as jumping in the air and falling in slow motion (in some cases). Enjoy!
