Well he mainly does it because we have shitty hangers and if he hangs them through the neck/arms it makes dimples in the shoulders. He also wears tall sizes so hanging them that way takes up a ton of room height-wise - at our old place's closet the ends would drag the top of the next shelf or the floor. Folding them you can also put them on tiered pants hangers to save space.

It's also nice because since they're shorter folded you can use the space underneath for shoes or whatever.

• Hang your pants on a hanger like this to save space.
  
• If the closet has a sliding door, remove it and mount a curtain like this. Make sure you mount it in such a way that the curtain can slide easily along the rod. It will make it much easier to access your closet. Treat the curtain like a giant piece of art (pick a design and color you like), since it will take up a lot of visual space.
  
• Pick up a hanging shoe organizer too.

My 1bd apartment that I share with my boyfriend only has ONE CLOSET that also has to store misc non clothes stuff so I just bought a freestanding portable open wardrobe thing where I keep most of my "outfit clothes" (t-shirts/gym/loungewear gets shoved in a fabric hanging shelf in the built-in closet, and I have a tiny set of drawers for socks and underwear that also lives in the closet). I fold knits that would stretch out if kept on hangers and just stack them on the bottom shelf, and hang up everything else. For lighter pants I use these multi hanger things to save space.
