Greenhouse Size Calculator
Calculate floor square footage, interior cubic volume, bench surface area, and maximum plant pot/flat capacity.
Spatial Planning: Greenhouse Size & Plant Capacity Calculator
Whether building a commercial nursery or backyard hobby greenhouse, optimizing space utilization ensures maximum crop return per dollar of construction cost. Our greenhouse size calculator computes floor footprint, interior air volume, aisle vs bench space ratios, and total plant capacity for standard pot sizes.
Bench Space vs Aisle Space Ratios
In a standard stationary bench layout, approximately 60% to 65% of floor space is devoted to growing benches, while 35% to 40% is reserved for walking access aisles (minimum 30-inch aisle width). Upgrading to rolling benches increases usable growing area up to 80% to 85%.
