Vegetable Yield
Estimate your home vegetable garden harvest yield based on crop type, row length, and number of rows. Free online garden planner with yield charts and area breakdowns for 30+ vegetables.
About This Calculator
The Vegetable Yield Calculator helps home gardeners and small-scale farmers estimate how much produce they can harvest from their garden. By selecting a vegetable crop and entering your garden dimensions, you get an instant estimate of total yield, number of plants, and garden area needed.
The calculator uses average yield-per-plant data combined with crop-specific plant spacing to compute the number of plants that fit in your garden. The garden area calculation includes 1.5-foot gaps between rows and 1.5-foot borders along the edges for comfortable access and tending. You can choose between direct seed sowing and transplanting seedlings, which affects the spacing distance.
Supported crops include tomatoes, peppers, cucumbers, corn, beans, peas, broccoli, cabbage, cauliflower, carrots, lettuce, onions, potatoes, pumpkins, watermelons, and 20+ more vegetables. Each crop has its own spacing requirements and expected yield per plant based on average home garden conditions.
Regional Notes
India (IN): Garden sizes are often smaller, with raised beds and container gardening popular. Row lengths of 10-20 ft with 2-4 rows are common for home gardens. Leafy greens and gourds grow well in the Indian climate.
United States (US): Typical home garden plots range from 200-600 sq ft. Popular crops include tomatoes, peppers, squash, and sweet corn. Many gardeners use raised beds with intensive planting techniques.
United Kingdom (UK): Allotment gardens and traditional row planting are common. Plot sizes typically range from 200-500 sq ft. Hardy vegetables like brassicas, root vegetables, and legumes are popular choices.
Frequently Asked Questions
How does the Vegetable Yield Calculator work?
The calculator estimates harvest yield by multiplying the number of plants by the average yield per plant for your chosen crop. The number of plants depends on your row length, number of rows, and plant spacing distance specific to each vegetable. The garden area includes 1.5-foot gaps between rows and along boundaries for comfortable tending.
What vegetables can I calculate yield for?
The calculator supports 30+ vegetables including tomatoes, peppers, corn, beans, peas, cucumbers, broccoli, cabbage, carrots, lettuce, potatoes, pumpkins, watermelons, and many more. Each vegetable has its own spacing requirements and average yield per plant data.
Is this calculator free?
Yes, it is completely free to use with no registration required. You can share your calculations via URL.
What is the difference between seed and seedling mode?
Seed mode uses direct sow spacing which is typically closer together, while seedling (transplant) mode uses wider spacing for started plants. Different spacing affects how many plants fit in your garden and therefore your total estimated yield.
How accurate are the yield estimates?
Yield estimates are based on average marketable yield per plant for home gardens. Actual yields vary based on soil quality, climate, water availability, pest management, and crop variety. Use these estimates as a planning guide.
What is an average home garden size?
For an individual, 100 sq ft is sufficient. A couple may need 200 sq ft, a family of 3-4 members requires 300-500 sq ft, a large family of 5+ needs 600-800 sq ft, and a very large family of 8+ needs 1000+ sq ft.
How many plants per person should I plant?
A typical guideline is 2-4 plants per person for most vegetables. For example, a family of 4 would plant around 15 broccoli plants. Tomatoes and peppers are typically 2-3 plants per person, while root vegetables like carrots require more plants per person.
