Full Size Pot vs Mini Pot

[TV Robot]

Is anyone aware of any differences aside from size?

I can't think of any diference except maybe a larger pot has a better resolution, because of the distance circumfrance part of it, but thats just a guess

Resolution?

Some might argue that a larger physical area would cut back on contact noise, but whether or not you would notice a difference in practice would depend on application the pot is used in.

They would be used to replace full size pots in an octave pedal schematic, as I may decide I want it onboard the guitar and of course if saving space is an option when it comes to onboard effects it helps to try to save as much space as possible. In any case I was just wondering and I appreciate the help.

I've been told that the mini-pots are JUNK.  Can't be more specific about it though.

Electrically, there's usually little or no reason to use the 2W pots most guitar and effects pedal makers use. Little 1/4 watt trim pots would work. But, mechanically, the 2W parts are much more robust. You put a mini-pot in, and the chances of it breaking can't even be described as "chances"; it's a sure thing. The 2W parts you can usually kick around quite a bit before they get hinky. For a stomp box, a really good design would install guards around the pots in addition to using the 2W parts. Legs and feet are heavy, with a lot of inertia. Put some shoes on, and you can break things with almost no effort at all.
