Yes. Archery was divided into 4 weapon types:
Short bow - base 2
Longbow - base 3
Light crossbow - base 3
Heavy crossbow - base 4
I don't remember the min/max dimensions of each. It should be in the chart with the rest of the weapons.
In addition to this, if wielding a bow and another weapon using the two weapon skill, the bow is no longer automatically the longer of the two weapons. If you are wielding a short bow in one hand you may use a longsword in the other. However if you use a longbow you are still limited to a short weapon in the other hand.
Bows and crossbows still use arrows and bolts respectively, regardless of which size.
