Plant Spacing Calculator
The plant spacing calculator helps gardeners and growers estimate how many plants fit in a bed, row, greenhouse, or small plot. It is useful for tomato spacing, pepper spacing, cucumber spacing, leafy greens, cabbage, beans, and custom crops.
What the tool calculates
Enter bed size, row spacing, plant spacing, crop preset, and seedling buffer to estimate rows, plants per row, total plant count, plants per square metre, and rough harvest potential.
Why spacing matters
Spacing affects airflow, disease pressure, light, harvest size, irrigation, and how easy it is to work inside a garden bed or greenhouse.
Use with planting calendars
After spacing the crop, use the seed starting and planting calendar to decide when to sow, transplant, and succession plant.

Frequently asked questions
How many tomato plants fit in a raised bed?
It depends on the bed size, row spacing, plant spacing, variety, pruning method, and whether plants are staked or trellised.
Is closer spacing always better?
No. Tight spacing can increase disease pressure and reduce airflow, especially for tomatoes, cucumbers, peppers, and leafy crops in humid conditions.
Can I use this for greenhouse beds?
Yes. Enter the bed dimensions and spacing you plan to use, then adjust based on airflow, access paths, and crop training method.
