-Many wallets do not allow for the creation of wallets with more than a 12 word pneumonic phrase. You will notice from the tables above that despite the unique amounts of entropy used, the seed remains the same length of 512 bits. From a security perspective, the amount of entropy actually used for the production of HD wallets is roughly 128 bits, which equals 12 words.  Providing more than 12 words produces additional entropy which is unnecessary, and this _unused_ entropy is not used for the derivation of the seed in the way that one might intially suspect. From a usability perspective, 12 words is much easier to write down, back up, and store, so stick with 12 words!
