Plant Calculator
Calculate how many plants can fit in a given area.
Quickly estimate how many plants your garden can handle.
Proper spacing is one of the most overlooked yet powerful elements of a successful garden. Overcrowded plants compete for nutrients, light, and airflow — leading to stunted growth and lower yields.
Our mini plant spacing calculator lets you get a fast estimate of how many plants will fit in your garden bed based on your chosen spacing. Simply enter the dimensions of your space, select a plant type or spacing distance, and get an instant result.
It’s perfect for home gardeners, raised bed planners, and anyone who wants a quick overview before diving deeper.
