Plant Spacing Calculator
Plan your planting layout with confidence. Provide the size of the garden bed and the recommended spacing, and the calculator estimates the number of plants you can grow on a square grid.
Use as a planning guide; adjust for specific plant needs.
Examples
- Area 180 ft², spacing 1.5 ft ⇒ 80 plants
- Area 64 ft², spacing 1 ft ⇒ 64 plants
FAQ
Does it assume a square grid?
Yes, spacing is measured between rows and columns.
Can I use inches?
Convert inches to feet before entering.
Should I round up?
The calculator already rounds up so you have enough plants to cover the bed.
Does it account for paths?
No, subtract walkway areas before calculating.
How can I adapt the result for staggered or triangular spacing?
Triangular or hexagonal spacing can increase capacity by about 15%. Multiply the output by 0.87 to approximate the number of plants needed in that arrangement.
Additional Information
- Results are rounded up to ensure you purchase enough seedlings or seeds.
- For rectangular beds, multiply length by width to get area before using the calculator.
