Space for mounted character

[noretoc]

I am having a bit of trouble with the space a character occupies on a mount. Is he concidered as having a 10' space like the mount, or does he occupie a five foot space in the area of the mount. If the latter which five foot square.
Thanks.

 

[Altamont Ravenard]

IIRC, the character occupies the same space as the mount, and uses his reach.

The rider occupies the exact same space as its mount, but uses its own reach.

 

[Lord Pendragon]

The rider occupies the exact same space as its mount, but uses its own reach.

This is correct.
