Plant Spacing Grid Calculator
Calculate how many plants fit in your garden area based on dimensions and recommended plant spacing.
Planting Grid
Plant Spacing Grid Formula:
Plants per row = Floor(Area Length / Spacing) + 1
Number of rows = Floor(Area Width / Spacing) + 1
Total plants = Plants per row × Number of rows
Common plant spacing (center-to-center):
| Plant | Spacing |
|---|---|
| Lettuce | 6–8 in |
| Carrots | 2–3 in |
| Tomatoes | 24–36 in |
| Peppers | 18–24 in |
| Squash | 36–48 in |
| Herbs | 12–18 in |
| Flowers | 6–18 in |
Square foot gardening uses a grid where each square foot holds a specific number of plants based on size.
Tips:
- Leave a border of half-spacing from garden edges
- Staggered rows can fit ~15% more plants
- Check seed packet for specific spacing recommendations
