Why is everything twice as big?

This is relevant because... european men often go through doors horizontally?

Why make a door that fits someone perfectly anyway?

If all doors were made that way, then my house would have 5-foot-seven doors and ceilings, and half of my friends would have to crouch to enter!

There's a player at my table who is always asking for the dimensions of objects and for no apparent reason. I could describe a room with a bed, the size of which does not matter one bit, but he needs to know. And it's never connected to any in game element. It's slightly annoying. I usually just give him a vague answer so he has to use his imagination to fill in the blanks.

Edit: upon further consideration, something you might want to consider was an idea I cooked up a while back. Instead of using 5 ft squares, reduce them to 2.5 ft squares. It allows a much better level of granularity, but it will take some time to get used to. With this level of detail, you can have your beds and double doors at 7.5 ft in length, which is much closer to reality.

I did this back in the 70s & 80s. I stopped because it was a P.I.T.A. communicating this to the players.

The average American hand occupies a 5' cube.

Don’t you mean “sphere”?
