How it works
The calculator divides bed width by row spacing and bed length by in-row spacing, using whole rows and positions only.
positions = floor(width ÷ row spacing) × floor(length ÷ in-row spacing)Worked example
A 12 ft × 4 ft bed with 12 in rows and 4 in seed spacing fits 4 rows with 36 positions per row, or 144 positions.
Assumptions
- The layout uses approximately half-spacing margins at the bed edges.
Limitations
- Seed packets and crop-specific guidance take precedence over a generic spacing calculation.
