How Much to Plant Per Person to Feed a Family for a Year
By Survival Garden Company • Complete 12-Month Homestead Calorie Matrix
The single biggest mistake new homesteaders make is planting for summer salads rather than winter survival. When global supply chains stall or food prices spike, a garden bed packed with lettuce and radishes will leave your family hungry.
True food independence requires calculating your garden in pounds of harvest, storage longevity, and usable calories. Below is the exact baseline formula to determine how many plants, vines, and row feet you need to sustain each person in your household for a full 12-month cycle.

These calculations represent the baseline production needed for one adult equivalent for 365 days of self-reliance:
| Staple Crop | Plants / Row Ft (Per Person) | Expected Harvest | Preservation Method |
|---|---|---|---|
| Seed Potatoes | 25 – 35 plants | 75 – 120 lbs | Root cellar (45–50°F unwashed) |
| Dry Storage Beans | 20 – 30 plants | 15 – 25 lbs (dried) | Airtight Mylar / jars + O2 absorber |
| Winter Squash | 4 – 6 vines | 15 – 25 squashes (~60 lbs) | Cured dry pantry (50–55°F) |
| Paste Tomatoes | 8 – 12 plants | 80 – 120 lbs | Water-bath canned sauce/paste |
| Storage Carrots | 40 – 60 row feet | 40 – 60 lbs | In-ground mulch / root cellar |
| Hardneck Garlic | 25 – 35 cloves | 25 – 35 bulbs | Cured, braided, or mesh bags |
| Grain / Flour Corn | 30 – 40 stalks | 10 – 15 lbs meal | Dried & ground into flour/meal |
| Quick Greens (Spinach/Kale) | 15 – 20 row feet | 12 – 16 lbs | Fresh eating, blanching & freezing |
Adjusting for Family Demographics
A generic "multiply by number of heads" approach will either over-exhaust your beds or leave you under-supplied. Use these standard caloric ratios:
- Adults (Ages 18–59): 1.0 Unit (Baseline ~2,000–2,200 kcal/day)
- Active Teenagers (Ages 13–17): 1.25 Units (Requires ~2,600–3,000 kcal/day)
- Seniors (Ages 60+): 0.80 Units (Lower baseline metabolic rate)
- Children (Ages 1–12): 0.60 Units (Scaled nutrition & calorie needs)
Example: Planning for a Family of 4
For a family of 2 Adults (2.0) + 1 Teenager (1.25) + 1 Child (0.60) = 3.85 Caloric Units:
- Potatoes: $3.85 \times 30 = \mathbf{115\text{ plants}}$ (Yielding ~400+ lbs)
- Dry Beans: $3.85 \times 25 = \mathbf{96\text{ plants}}$ (Yielding ~72 lbs dried)
- Paste Tomatoes: $3.85 \times 10 = \mathbf{38\text{ plants}}$ (Yielding ~450+ lbs for canning)
- Winter Squash: $3.85 \times 5 = \mathbf{19\text{ vines}}$ (Yielding ~75 squashes)
