Plan a planting grid and know how many plants your bed will hold before you open a seed packet. Enter the bed length and width in inches along with the spacing you want between plants in a row and between rows, and the calculator lays out a rectangular grid to count the plants that fit. It then works backward from your target plant count using an expected germination rate so you know how many seeds to sow to hit that number after thinning. Tight spacing raises yield per square foot but reduces airflow, so match the numbers to the crop on your seed packet. Everything is calculated instantly in your browser, letting you test different spacings and bed sizes in seconds with no signup.
