[RPG] Does creature size affect weapon damage


I have no idea whether or not this is true in D&D 5e; it was in 3.5 and Pathfinder, but it is not mentioned in the 5e Player's Handbook. For example, in 3.5 and Pathfinder, a halfling's longsword would do 1d6 whereas a human's would do 1d8.

Any mention of this in 5e?

Weapon sizes are addressed in the Creating a Monster section of the DMG. On p 278 it says:

Big monsters typically wield oversized weapons that deal extra dice of damage on a hit. Double the weapon dice if the creature is Large, triple the weapon dice if the creature is Huge, quadruple the weapon dice if it's Gargantuan.

A creature has disadvantage on attack rolls with a weapon that is sized for a larger attacker. You can rule that a weapon sized for an attacker two or more sizes larger is too big for the creature to use at all.

While this is different from the "Heavy" notation used in the PHB it is not inconsistent if we assume that "Heavy" weapons are sized for Medium and the others are for Small.
