How many people can fit into each size of a house?

[Hatfright]

Searched all over, but all I could find is a 3 year old reddit post, so here I am.

Just how many people can be in a house of each size at once?
Noticed small ones tend to overcrowd pretty quickly in case of some events, but didn't had the chance to count how many exactly does it fit.
Saw the info that large one can fit up to 100 people before doors "shut", but I find it hard to believe due to max member count FC can have. And basically no info on medium houses.

Also an interesting question: if an FC house is crowded to it's limit and someone goes into a room of FC member (or workshop), does it still counts toward number of people in the house or does it leave the spot for someone else to enter?

Any insite on the matter is greatly appretiated.
