[dm-crypt] LUKS overhead?

We recently started using ownCloud which has an encryption-at-rest option.
 However, their encryption scheme increases file size by 34%.  We need to
have our files encrypted at rest so I was thinking that maybe LUKS was the
better way to go.  Can anyone tell me if we'll see the same kind of
increases in file size?  I ask because we're trying to plan on how much
storage we should buy.
