Garden Area Calculator

Understanding Garden Area

Calculating your garden area is the first step in planning a successful garden. Whether you have a small raised bed or a large backyard plot, knowing the exact area helps you determine how many plants you can grow, how much soil and mulch you'll need, and what your total costs will be.

Garden Area Formulas

Different garden shapes require different area calculations:

• Rectangle: Area = Length × Width
• Circle: Area = π × Radius²
• Triangle: Area = (Base × Height) ÷ 2
• L-Shape: Area = (Length1 × Width1) + (Length2 × Width2)
• Oval: Area = π × (Length ÷ 2) × (Width ÷ 2)

Plant Spacing Guidelines

Proper plant spacing is crucial for healthy growth and maximum yield:

• Tomatoes: 24-36 inches apart
• Lettuce: 6-12 inches apart
• Carrots: 2-3 inches apart
• Peppers: 18-24 inches apart
• Herbs: 6-18 inches apart (varies by herb)
• Squash: 36-48 inches apart

Soil and Mulch Calculations

Calculating soil and mulch needs:

• Soil Volume: Area × Depth (convert to cubic feet)
• Mulch Volume: Area × Mulch Depth (typically 2-4 inches)
• Conversion: 1 cubic yard = 27 cubic feet
• Recommendation: Add 10% extra for settling and coverage
