Plant Spacing Calculator
Seed packets and transplant tags give the spacing between plants. Enter how long the row is and the gap you want, and this counts the plants and shows how many fit each foot.

How it works
Divide the row length by the spacing to count the gaps, then add one for the first plant. The count is rounded down, so no plant falls past the end of the row.
Plants per foot is one foot divided by the gap between plants, so a closer spacing gives more plants per foot.
Worked example
A row 50 ft long with plants 12 in apart holds 51 plants, which is 1 plants for each foot.
Questions
Why add one to the count?
A row has one more plant than it has gaps, since the first plant sits at the start. Subtract one if you plan to start the row a gap in from the end.
What if my spacing is uneven?
Use the average gap. Small differences in spacing rarely change the total much.
Is spacing the same as row width?
No. Spacing is the gap along the row. Row width is the distance from one row to the next, which is a separate measurement.
