How it works

Square-grid baseline = floor(length ÷ plant spacing) × floor(width ÷ row spacing). The staggered result shown here uses the same conservative row/column count rather than claiming extra plants fit at the edges.

Planning estimates depend on your measurements, product labels, material density and site conditions. For purchased products, follow the manufacturer's label.
