Garden Bed Soil & Plant Count Calculator
Estimate soil volume and how many plants fit in a bed from your dimensions and spacing assumptions. Switch between imperial and metric units, then adjust the buffer for paths, rounding or spare plants.
Spacing is an assumption, not a crop rule
This tool counts a regular grid using your entered within-row and row spacing, then adds your buffer. Choose spacing for the crop and variety you are actually growing; extension planting tables often vary by crop, cultivar, bed width and production system.
