Proper plant spacing is crucial for healthy growth and maximum harvest. Our crop spacing calculator helps you determine the optimal distance between plants based on your growing method, crop type, and available space. Whether you're planning a traditional row garden, raised bed, square foot garden, or container plantings, get accurate plant counts and layouts instantly.
Crop spacing refers to the distance between plants both within rows (plant spacing) and between rows (row spacing). Proper spacing ensures adequate light, air circulation, and root space for each plant while maximizing land use. Different crops and growing methods require different spacing to achieve optimal growth and yields.
Plant Population Formula
Total Plants = (Area Width ÷ Row Spacing) × (Area Length ÷ Plant Spacing)Correct spacing allows each plant to reach its full potential without competing for light, water, and nutrients.
Adequate air circulation between plants reduces humidity and prevents fungal diseases from spreading.
Calculate exactly how many plants fit in your garden to avoid overcrowding or wasted space.
Proper spacing provides access for weeding, watering, pest inspection, and harvesting.
Design 4×8, 4×4, or custom raised bed layouts with intensive spacing for maximum harvests.
Apply Mel Bartholomew's square foot method with automatic plant-per-square calculations.
Plan traditional row gardens with proper spacing for mechanical cultivation or hand tools.
Determine minimum container sizes and plant counts for pots and grow bags.
Row spacing is the distance between parallel rows of plants. Plant spacing (or in-row spacing) is the distance between individual plants within the same row. Both affect total plant count and growing conditions.
