Seed Spacing Calculator
Calculate how many seeds to plant and at what spacing for garden beds. Enter values for instant results with step-by-step formulas.
Formula
Plants Per Row = (Row Length × 12) / Spacing + 1 | Total = Plants × Rows
Divide row length by plant spacing. Add 1 because the first plant goes at position 0. Multiply by number of rows.
Frequently Asked Questions
How do I calculate plant spacing for maximum yield?
Square foot gardening assigns each plant a grid space: 1 per square foot for tomatoes and peppers, 4 for lettuce, 9 for beets, 16 for carrots and radishes. Traditional row spacing is wider to allow cultivation equipment. Intensive spacing increases yield per area but requires more fertile soil and consistent watering.
