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[cite: 3477, 4026]. When global supply chains stall or food prices spike, a garden bed packed with lettuce and radishes will leave your family hungry[cite: 3478, 3741].
True food independence requires calculating your garden in pounds of harvest, storage longevity, and usable calories[cite: 3479, 3742]. 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[cite: 3853, 4032, 4072].

These calculations represent the baseline production needed for one adult equivalent for 365 days of self-reliance[cite: 4032, 4072, 4895]:
| 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[cite: 4893]. Use these standard caloric ratios[cite: 4895]:
- Adults (Ages 18–59): 1.0 Unit (Baseline ~2,000–2,200 kcal/day) [cite: 4891, 4895]
- Active Teenagers (Ages 13–17): 1.25 Units (Requires ~2,600–3,000 kcal/day) [cite: 4820, 4895]
- Seniors (Ages 60+): 0.80 Units (Lower baseline metabolic rate) [cite: 4892, 4895]
- Children (Ages 1–12): 0.60 Units (Scaled nutrition & calorie needs) [cite: 4818, 4895]
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[cite: 4823, 4895]:
- Potatoes: $3.85 \times 30 = \mathbf{115\text{ plants}}$ (Yielding ~400+ lbs) [cite: 4006, 4053, 4823]
- Dry Beans: $3.85 \times 25 = \mathbf{96\text{ plants}}$ (Yielding ~72 lbs dried) [cite: 4008, 4054, 4823]
- Paste Tomatoes: $3.85 \times 10 = \mathbf{38\text{ plants}}$ (Yielding ~450+ lbs for canning) [cite: 4013, 4056]
- Winter Squash: $3.85 \times 5 = \mathbf{19\text{ vines}}$ (Yielding ~75 squashes) [cite: 4011, 4055]
