A garden can look generous when its full length and width are measured, then become difficult to use once every available strip is turned into a bed. Access needs space too. The bed plan should account for reaching, watering and carrying materials before you count its growing area.
The Garden Bed Layout Planner places whole parallel beds across a garden rectangle. It removes outside access on all four edges, then includes the entered path between each neighbouring pair of beds. It is a simple straight bed layout rather than a drawing program.
An eight by five metre garden
For a garden 8 m long and 5 m wide, leave 0.5 m outside access on every edge. That creates a usable internal length of 7 m and width of 4 m.
Beds 1.2 m wide with 0.5 m paths between them fit as two complete beds across that width. Their growing area is 2 × 1.2 × 7, or 16.8 m². The full garden is 40 m², so 23.2 m² lies outside the modelled growing beds.
That 23.2 m² is not all a precisely drawn walkway. It includes the outside access, internal path and any remaining strip that cannot accommodate another whole bed. The calculator labels it as area outside growing beds to keep that distinction clear.
Try the path before reducing it
A narrow gap that works on paper may be inconvenient when a hose, watering can or basket is in use. Enter an access width that suits the way you will actually tend the garden rather than reducing it just to gain another bed.
Changing bed width and path width together can obscure why a count changed. Adjust one at a time, check the number of whole beds, and compare the growing area. The extra row space may matter more than the largest possible total area.
Beds run along the entered garden length. The tool does not rotate them automatically or fill leftover strips with beds of a second size. If you want to compare the opposite orientation, swap garden length and width yourself and keep the other assumptions the same.
From a layout to quantities
Once the count and bed length are settled, transfer the inside dimensions of each constructed bed to Raised Bed Soil Calculator. The layout width is a planning dimension; wall thickness can make the actual soil holding width smaller.
Use Plant Spacing Calculator for the crop grid within each bed. Its edge setback is a plant centre measurement, not the walking path used in this layout. Keeping those stages separate prevents access space from being counted as planting ground.
