I plan to make bifold panel closet doors for 3 openings/entrances. If
one opening is 5 feet wide, I know I don't want the doors to be an exact
30" for each side (or do I?) due to obvious reasons. How much clearance
should I provide? Is there a general guide/rule for door size with
specific opening size?

Assuming the opening really is 60", and square, I'd make them 30" and
then plane them to size before hanging.
