From my point of view:
-Uses 100% of the a single bed.
He moves from left to right
Open and stretch his body till the entire bed is occupied
He will sleep on the bed like a starfish

-Uses 70% of the bed when the other 30% of the bed was occupied by another person
He stretches his legs and occupy 70% space
The poor person had to suffer on the 30% of space on the bed

Snores when sleep

- Snores the entire night
Irritating noise that will bother you the entire night
Noise from volume 2 to volume 10!!
Different frequency of noises!!

- Sneak in to sleep at 2am
No sound was produced
sleep at the corner of the room
a small movement of sleeping bag, make you think there is something trapped
or something is hidden in it.

- woke up at 5am
didn't really slept back after that
turning from left to right
making movement sounds.

This does not apply to all guys, but is just my observation on how they sleep.
Have fun reading!
