In D&D 5e, there are several advantages to wielding a Heavy Two-Handed weapon in combat. However, historically, all six of the ones in the Weapons table were quite inconveniently long. You typically carried them leaning against your shoulder rather than at your waist, which would be problematic in low-ceilinged or otherwise cramped locations. (Local tavern, anyone? "Pardon me. 'Scuse me. Pardon me. Sorry.")
Beyond "the DM has discretion," is there any specific official guidance for applying these real-world limitations to D&D, either inside or outside of combat? Or for ignoring them altogether?
For the three weapons that have Reach (glaive, halberd, and pike), I could imagine any additional inconvenience being a reasonable tradeoff for keeping your enemies 5 more feet away from you, but the other three (battleaxe, greatsword, and maul) get no such benefit.
