Museum Exhibit Spacing Calculator

Usable Area is calculated directly as Gallery Floor Area times (1 minus Circulation Space as a percentage) -- Gallery Floor Area is a straightforward proportional factor, so it moves Usable Area, and Visitor Capacity which is derived from it, by exactly the same percentage you change it. Circulation Space's effect is real but structurally smaller, since it only ever subtracts a percentage share of the total.

Number of Exhibits, since Wall Length Needed is Number of Exhibits multiplied by the sum of Avg Exhibit Width and the required spacing -- it's a direct linear multiplier on the whole formula, more influential than Min Viewing Distance or Avg Exhibit Width, which only add to what gets multiplied per exhibit.

Area per Exhibit is Usable Area divided by Number of Exhibits -- Gallery Floor Area scales the numerator up in exact proportion, while Number of Exhibits scales the denominator down in exact inverse proportion, so the two forces are mathematically tied in magnitude, just opposite in direction.

No. Visitor Capacity is calculated purely from Usable Area, which itself depends only on Gallery Floor Area and Circulation Space. Min Viewing Distance and Avg Exhibit Width matter for Wall Length Needed and Wall Utilization, but they never enter the Visitor Capacity or Usable Area formulas at all.

Wall Utilization compares Wall Length Needed against an estimated gallery perimeter derived from Gallery Floor Area -- Number of Exhibits has the largest effect on it since it directly scales Wall Length Needed, while Min Viewing Distance and Avg Exhibit Width contribute smaller amounts through the per-exhibit spacing calculation. Circulation Space has no effect on Wall Utilization at all, since neither side of that ratio references it.
