Brendan Lally on map scales.

**Ok**, currently one square holds one person, even if they stretch out

their hands, they don't occupy more than one square. This therefore

suggests that the squares are sides of at least 1 fathom (that being

the distance of someone between their outstretched hands. This is

consistent with a bed being 1 square. Given that one tick is about 1

second of game time (not real time), and that a player moves 1 square

a tick at speed 1, this gives a walking speed such that at speed of

1.0 a mile is covered in **(1 mile is 8 furlongs, is 80 chains, is 880
fathoms) 880 seconds, or 14.7 minutes** (which is about correct).

The indoor maps are smaller on the outdoor maps, it tends to be the

case, that **1 square outdoors correlates to 8-12 squares indoors**.

**If the indoor squares are 1 fathom across, then the outside ones are
about 10 fathoms across. Or almost 1 chain (11 fathoms)**. Since the

value of 11:1 is well within the range of values that are used, and

since it is a round number. It seems reasonable to consider each of

the world map squares to be 1 chain. All the more so since this is the

size used for buildings, and buildings have in the real world been set

out on a scale of 1 chain for a house.

From http://en.wikipedia.org/wiki/Chain_%28length%29

“In the laying out of towns in Australia and New Zealand, most

building lots in the past were a quarter of an acre, measuring one

chain by two and a half chains, and other lots would be multiples or

fractions of a chain. As a consequence, the street frontages of many

houses in these countries are one chain wide — roads were almost

always one chain wide (20.117 m) in urban areas, sometimes one and a

half (30.175 m) or two chains (40.234 m).”

In game most roads are 1 or 2 squares wide, which also fits in nicely.

Furthermore, by adopting this standard, it means that **10 squares on
the world map is 1 furlong**, which gives a nice way to measure

distances, because it is also about 1 screen (default is a map view of

11×11 IIRC). in the gtk2 client, it is about twice that, so you see

one furlong in all directions.

Ooh, and it also makes the distance from Scorn to Navar about 9 miles

(75 furlongs), which is a somewhat saner estimate than 1000's of

miles. 9 miles says 'you *can* walk this but probably don't want to do

so very often'.
