Rows × plants per row

Bed length and width in meters and spacing between plants in meters—rough plant count on a square grid.

FAQ

How many plants fit on a rectangular grid?

With bed length and width and a positive spacing (same units), plants along each axis are ⌊length ÷ spacing⌋ and ⌊width ÷ spacing⌋; total count is the product. Edge offsets and staggered rows are not modeled.

What does this estimate leave out?
