I'm wondering because of Greatbow vs shortbow. Obviously the arrows are going to be of different sizes, and I got to wondering. Arrows for Greatbow, we'll call them great arrows, are they the size of small spears? Or would they be closer to the length of a longsword?
Same thing with the rest of the arrows, what are they the most comparable with visually?
In terms for this question, I'm not asking for damage-wise. What I'm actually asking for is what does the book/rules/DMs say about the arrow sizes visually. The reason why I ask this is because when I think greatbow, I immediately think of the Dragonslayer Greatbow from Dark Souls 3 and the Dragonslayer Greatarrows that it uses. Those, in comparison to the player is a small spear. A longbow in the same game has arrows roughly the same length as a shortsword, iirc. Of course, not the same width.
