Increasing a weapon's size.

[Delenot]

When you increase a weapons size/damage die increment, is there ever a size that will grant reach when the normal size of a weapon does not?

Common sense, yes...I know, would figure that a 2 handed weapon made large, huge, etc, would have a longer reach. But it's that covered anywhere?

[Chess Pwn]

No it never changes it's reach. A small sword and gargantuan sword on the same character work the same with reach

[Imbicatus]

No. Weapon size increases do not increase reach. You need to actually increase in size or be under a longarm type effect to gain reach.

[CampinCarl9127]

Reach is based on the character size, not the weapon size.

[Nefreet]

Hilariously this also means that a Human can wield a tiny-sized polearm as a light weapon (at -4 to-hit, of course) and still have reach.
