Example Data Table
| Example | Rows | Cols | Shape | Section size | Path | Depth | Spacing |
|---|---|---|---|---|---|---|---|
| Backyard Veggie Grid | 2 | 3 | Rectangular | 1.2 × 0.9 | 0.45 | 0.30 | 0.30 |
| Herb Patio Modules | 1 | 4 | Circular | Diameter 1.0 | 0.30 | 0.25 | 0.25 |
Units follow your selection. These rows show typical modular layouts for quick planning.
Formula Used
Circular section area = π × (D/2)²
Total bed area = sections × section area
Footprint width = rows×cell + (rows−1)×path + 2×clearance
Soil volume = total bed area × bed depth
Mulch volume = total bed area × mulch depth
Outer only edging = 2 × (footprint length + footprint width)
Circular slots ≈ ⌊area/spacing²⌋
These formulas provide planning-grade estimates. Adjust for curved edges, irrigation hardware, and crop-specific spacing when preparing final drawings.

1) Why sectional layouts improve garden performance
A sectional configuration breaks a growing area into repeatable modules. This improves planning because each section can be measured, amended, watered, and replanted without disturbing the whole site. Modular beds also simplify crop rotation and pest control, since tasks can be scheduled by section rather than by the entire garden.
2) Area and footprint data for smarter space use
The calculator separates total bed area from overall footprint. Bed area drives soil and mulch quantities, while footprint accounts for paths and perimeter clearance. This distinction is critical when fitting a layout beside fences, patios, or trees. Even a small change in path width can noticeably increase footprint area and reduce usable bed coverage.
3) Soil volume, depth, and handling estimates
Soil volume is computed as bed area multiplied by bed depth. Using the optional density input, the tool also estimates soil weight for handling and delivery planning. Weight data helps determine if bags, bulk delivery, or wheelbarrow staging is more practical, and it supports safer lifting plans during installation.
4) Edging lengths and cost benchmarking
Edging can be estimated per section for strong separation, or only around the outer footprint to reduce cost. The calculator converts edging length into a budget line item using your unit cost. This makes it easy to compare timber, composite, metal, or stone edging options and select a build approach that fits labor and maintenance goals.
5) Plant slots, spacing, and seasonal planning
Plant slots are estimated using spacing rules: grid spacing for rectangular beds and an area-based approximation for circular beds. This gives a practical count for seedlings, drip emitters, and labeling. If you adjust spacing for specific crops, the result instantly updates, helping you plan spring starts, succession planting, and harvest targets with clearer numbers.
FAQs
1) What does “footprint” mean in this tool?
Footprint is the overall rectangle that contains all sections, paths, and outer clearance. It helps you confirm the layout fits the available yard space before building.
2) Are plant slots an exact planting count?
No. Plant slots are a planning estimate based on spacing and bed area. Adjust spacing for each crop and reduce counts for borders, trellises, or access lanes.
3) Which edging mode should I choose?
Choose “per section” for strong separation and cleaner pathways. Choose “outer only” when you want a simpler border and lower edging cost with shared internal edges.
4) How accurate are soil and mulch volumes?
Volumes are based on geometry and depths you enter. Real projects may vary due to settling, mounding, and compaction. Add a small allowance if your soil is very loose or uneven.
5) What soil density value should I use?
Use a supplier value if available. Otherwise, typical moist topsoil is often around 1,100–1,400 kg/m³. The weight output is mainly for handling and delivery planning.
6) Can I use this for non-rectangular overall gardens?
Yes. Use the module grid to approximate your area, then keep extra clearance to match irregular boundaries. The tool is best for early planning and material estimating.
7) Why does path width change so many results?
Path width affects footprint length and width across multiple gaps. Wider paths increase total footprint area and can reduce the percentage of space used for beds.
