What is the maximum size a Source Engine map can be?

Hey there. Does anyone know the maximum amount of units a Source Engine map can have? This is a rather simple question, though I couldn't find the answer on Google. I only came across mapping tutorials that didn't even have the information, and people asking how they can get past the max grid size. Thanks in advance!

Just started up Hammer and took a look at it myself, looks like it's 32768 units from end to end on each axis.
