A few years ago I wrote about crawlspaces… after bashing my head pretty badly in a poorly designed crawlspace.
I’m not going to revisit my thoughts on crawlspaces, because I already covered the subject well… but I would like to talk about low doorways.

The Case Against Low Doorways
The thing about a crawlspace is that it demands your attention. Unless you’re a small child, a crawlspace demands that you stop, completely shift your body posture, and then enter. Any way you slice it, entering a crawlspace must be done knowingly and deliberately. This is not the case for low doorways.
A standard doorway in the United States is 80 inches tall (6.67 feet).
At 6’1, I am a reasonably tall guy… not very tall… just taller than the average American male (5’9).
When a doorway is slightly shorter than usual, it doesn’t always register, especially when the person passing through it is – say – immersed in some sort of game.
Speaking from experience, a low doorway can result in a harsh head-thumping.
Suggestions for Low Doorways
Sometimes a lower than average doorway is needed. Escape rooms have all sorts of unusual design constraints. When you need to use a low doorway, there are a few things that can make it safer:
- Pad it – A little foam goes a long way.
- Light it – It’s easier to avoid things that you see clearly.
- Limit passage – When you have a low doorway, avoid puzzles that require traversing that space.
Once I played a game where we were issued a hardhat to wear. I thought it was part of the immersion process but soon learned there was a practical and functional reason. Glad I still had it on my head because i don’t like wearing hardhats and almost took it off too soon.
If you have to have a doorway that is not standard then I suggest you make it significantly/obviously short or symbolic of something like a bank vault or ship’s watertight door so players are not innocently ignorant that the doorway could be a head bumper.
Padding is better than nothing and when I have hit my head on padded passages I did not get a cut or bruise. However, I have found that the process causes a neck wrenching that lasts much longer than the joy of the game.
Yeah, padding isn’t a cure-all… but it’s wayyy better than nothing.
