Square-foot module index

The units of a terrain system

This is a list of interconnecting terrain modules I have built for wargaming at home, starting in 2007.

Legend

The modules have a set of standardized interfaces. Each of these can be described by a code.

Current codes
Code Interpretation Example
Built-in base, 10 mm tall.

A base measures 300 × 300 mm if produced since 2019. Earlier modules are 298 × 298 mm.
River to edge. Implies 土 if 旧 is not stated. 3川: Three-way river piece.
River bend. Implies 2川 and that the indicated edges are adjacent.
Straight river. Implies 2川 and that the indicated edges are opposed.
Gentle slope along edge. 土2坂: Outer corner of hill.
Cliff face along edge. 坂崖: Outer corner between a cliff and a slope; no base.
崖坂: The same, mirrored. Such corners are chiral.
Unbroken 30 mm level along one edge. 2坂階: Medial slope.
Bump(s) in the middle.
Hole(s) in the middle. 土丘穴: Something with raised edges over a pit that digs into the base.
Legacy codes
Code Interpretation
Equivalent to 土 except that the base height is 40 mm. In 旧川 modules, the water surface is at a height of 10 mm; in newer modules it’s 3 mm.
Double-sized module. These measure 298 × 598 mm. Implies 旧.
