About Plant Spacing Calculator
We build fast, simple, and accurate garden layout tools designed for home gardeners, allotment owners, and landscapers.
Real Garden Plans Instead of Rough Guesses
Most gardening calculators simply take your total garden area and divide it by plant spacing squared (Area ÷ Spacing²). That rough math might work on paper for large farm fields, but it gives incorrect numbers for real garden beds where wooden edges, pathways, and border space limit where you can actually put plants.
Plant Spacing Calculator was created to solve this problem. Our calculator places each plant individually within your bed walls, leaves safe room around the borders, and creates a clear, printable plan before you buy your plants or dig your soil.
Backed by University Research
Different plants need different amounts of room to grow well. A bush tomato growing on a stake in a raised bed needs far less room than a climbing tomato spreading out in a large wire cage. We gather our spacing guidelines directly from trusted university agricultural extensions—including the University of Minnesota, Royal Horticultural Society (RHS), and the University of Florida.
