Hex size question

[cvannrederode]

Two things have brought me to this question...

Almost 20 years working with engineers.

A picture from Reddit of a guy who laid out a D&D five foot square in the ground.

So here's the question...in GURPS, are the hexes 36 inches point to point , or flat to flat?

Center-to-center, which is the same as flat-to-flat.

It's a measure of movement and distance, so imagine the path a figure takes moving from hex to hex. That distance is nominally one yard. The point-to-point distance (presumably between opposite points) isn't a particularly interesting measure, because that's not the way the figures move on the map.

Realizing this was almost* a revolution in my thought process on how to run GURPS combats in the early 90's...






* 'Almost' because I'd already been doing mapless and gridless map combats in GURPS and just leaning hard on tactical miniatures experience... and then I realized that GURPS tactical combat is gridless by design, the hex grid is only there as a convenience so you don't have to have tape measures at the table.

It gets real fun when trying to measure distances who aren't directly along one of the six facings, line one who would be along the line of a vertice.

Okay. So the "inradius" is 18". And as quick calculation: the vertex to vertex distance is 1.1547 yards (41.6 inches) -- that's twice the "circumradius" And each hex side is 20.8 inches.

So two people standing in one hex is very cozy.

Easiest way to visualize would be to get six 20.8" lengths and lay them out.

That's why you want to have a weapon with Reach Cozy - to cause crazy close combat casualties.
