Compare terrain module sizes across tables and storage.

Choose a size for one reusable collection. Check each table format, then see whether all required modules fit your available cases or shelves.

Comparison rules

Maximum modules in the collection Minimum coverage on every table (%) Table edge margin (cm, each side) Storage clearance (cm) Prioritize among feasible sizes Allow quarter-turns on tables and in storage

Storage clearance is reserved at each horizontal side and above the top layer, not between modules. Allow extra space for padding in your measured dimensions. Set minimum coverage to 100% if every tabletop must be fully covered.

Alternative table formats

Use one table setup at a time. The same collection is reused across formats.

Table 1

Name Width (cm) Depth (cm) Height allowance (cm)

Table 2

Name Width (cm) Depth (cm) Height allowance (cm)

2 of 6 rows

Storage available together

Enter free interior dimensions, after fixed obstructions. Each row is one physical case or shelf space.

Storage unit 1

Name Width (cm) Depth (cm) Free interior height (cm)

Storage unit 2

Name Width (cm) Depth (cm) Free interior height (cm)

2 of 6 rows

Module sizes to compare

Each candidate represents its own same-size collection. Use the full stored height, including fixed scenery.

Candidate 1

Name Width (cm) Depth (cm) Stored module height (cm) Safe to stack in equal-height layers

Candidate 2

Name Width (cm) Depth (cm) Stored module height (cm) Safe to stack in equal-height layers

Best under your chosen preference: 30 × 20 modules.

1 of 2 candidates meet every table's minimum coverage and height, the collection ceiling and combined storage capacity. Preference: highest worst-table coverage, then fewer modules.

Candidate	Reusable modules	Worst-table coverage	Storage capacity	Result
30 × 20 modules	12	100%	12	Meets constraints
30 × 30 modules	8	100%	4	Does not meet constraints

30 × 20 modules: layouts, storage and reasons

All entered constraints pass. Check physical clearances and safe stacking before building.

Reusable collection: 12 modules, the largest single-table grid below, not the sum. Each table is an alternative setup.

Unplaced: 0. Storage is assigned in entered unit order. Each candidate is a separate hypothetical collection.

30 × 30 modules: layouts, storage and reasons

Storage shortfall: 4 modules.
