Square Foot Garden Calculator

Plan a square-foot garden grid from bed dimensions and a chosen number of plants per one-square-foot cell.

Use an appropriate value for the crop and spacing method you intend to use.

How it works

The calculator converts the bed dimensions to feet, counts complete one-foot grid cells and multiplies the cell count by your chosen plants-per-square value.

plant capacity = full 1-ft² cells × plants per square

Limitations

  • Crop spacing varies widely. The calculator does not prescribe how many plants of a particular crop should occupy each square.
