Pumpkin Plant Spacing Calculator
Cucurbita pepo / C. maxima / C. moschata
Start with the source-backed 36-inch spacing default, then enter your bed length and width to calculate an approximate plant count, seeds or starts needed, and the spacing used. Defaults are editable so your variety and growing system can take priority.
Quick spacing answer
How far apart should you plant pumpkin?
Start with 36 inches between plants using a rows layout. The source-backed range in this dataset is 24–48 inches.

Pumpkin spacing chart
These values come from the existing crop record. The density column is derived planning math and does not add a new horticultural recommendation.
| Context | Spacing | Geometric plants/sq ft |
|---|---|---|
| Dataset default | 36″ | 0.1 |
| Source-supported range | 24–48″ | Varies with selected spacing |
Plants per square foot is transparent square-grid planning math (144 ÷ spacing²), not an extension-service recommendation or a guarantee of field performance.
Pumpkin per square foot
At 36″ spacing, square-grid geometry equals approximately 0.1 plants per square foot. This is a geometric planning estimate based on the displayed spacing—not an agronomic guarantee. The calculator may use a different documented model for rows layouts.
Why pumpkin spacing changes
Variety, production system, support, and planting layout can change usable spacing. Plantometry keeps the sourced default editable and shows a range only when the crop record supports one.
How many pumpkin plants fit in my bed?
Use the calculator above with your bed dimensions. The result shows the approximate plant count, the spacing used, and seeds or planting material to prepare where appropriate.
