You may have already generated the borders of kingdoms, if not this list is from table 26 Random Kingdom Size. If you already have borders there is no need to regenerate new ones.
- 1d8 hexes on a regional map ( regional map hexes are 100 miles across on an earth size world)
- 10d10 miles approximate diameter
- Small Kingdom
- 3d6 hexes
- 10d10 x 5 miles
- Medium Kingdom
- 4d6 hexes
- 10d10 x 8 miles
- Large Kingdom
- 6d6 hexes
- 10d10 x 10 miles
- 8d8 hexes
- 10d10 x 20 miles
World size and Kingdom size
Medieval kingdoms are severely limited in their maximum size by lack of efficient overland communications and reliable sea travel.
No matter how much land a world has, kingdoms generally remain about the same size. If a world is unusually large or has a great deal of land area kingdoms will generally increase in number before increasing in size.
If you are using a system that has advanced technology and/or magic then this guideline may be irrelevant.
Coasts, Seas and Lakes
First sketch out the coastlines and any major body of water within the borders. Here’s a list from table 27.
- Archipelago-Kingdom is scattered across chains of fairly small islands, each are within a day’s sail 25-50 miles
- Major Islands-Kingdom occupies most of one or two major islands, bordered on all sides by the sea
- Coastal with offshore islands-A major portion of the kingdom border is a coastline, may have inlets, peninsulas and offshore islands under control of the kingdom.
- Coastal, no islands-A major portion of the kingdom border is a coastline with no significant offshore islands.
- Multiple coastlines-Kingdom borders on two or more major bodies of water, with coastlines on several sides.
- Landlocked with an inland sea-Kingdom has no exterior seacoasts but includes a major body of water. The inland sea is 6d8 hexes in extent on the kingdom map.
- Landlocked with major lakes-as above but kingdom features 1d4 major lakes each 4d6 hexes in size.
- Landlocked, no significant water-No major bodies of water exist although minor lakes (1 hex or less) and rivers may be common.
