Tomato Plant Spacing Calculator: How Far Apart to Plant Tomatoes
Tell it your tomato type and your bed size, and it tells you the right spacing plus exactly how many plants fit. No more guessing, no more overcrowded jungles.
Work out your spacing
Spacings follow standard extension service guidance: closer spacing works with excellent airflow, pruning and feeding; wider spacing is more forgiving. Rows assume you can reach the bed from at least one side.
The standard answer to how far apart to plant tomatoes: 18 to 24 inches between staked determinate plants, about 24 inches for trellised indeterminate vines with 36 to 48 inches between rows, and up to 36 inches for sprawling plants. Dwarf varieties squeeze into 12 to 14 inches. The calculator handles the row math for your actual bed so you get maximum plants without the overcrowding that invites blight.
