The definitions are fairly woolly, but generally speaking, to be classed as a single, a release can have up to three tracks, with each track up to 10 minutes and in total no longer than 30 minutes runtime.
Anything with three to five tracks, with a total run time of up to 25 or 30 minutes (depending on who you ask) can be classed as an EP.
Anything with a more than five tracks, and less than 30 minutes runtime is a mini-LP.
Anything with a longer runtime than this, is an LP, otherwise known as an album. Even if it only has one track.
