Measure each piece, then total the footprint fast. Add clearance space for comfortable movement too. See results instantly and export records for future projects.
| Piece | Type | Inputs (m) | Clearance (m) | Area (m²) |
|---|---|---|---|---|
| Patio table | Rectangle | L=1.40, W=0.80 | 0.10 | (1.60×1.00)=1.6000 |
| Round planter | Circle | R=0.25 | 0.10 | π×(0.35²)=0.3848 |
| Corner bench | L-shape | Outer 1.80×1.40, Cut 0.80×0.60 | 0.10 | (2.00×1.60)-(0.80×0.60)=2.7200 |

Outdoor rooms work best when every item has a measured base area. A clear footprint helps you balance seating, planters, grills, and storage without blocking irrigation lines or edging. When you know the occupied area, you can reserve open zones for circulation, pruning access, and seasonal rearrangement. This approach also appears in material takeoffs and helps verify that drainage slopes remain unobstructed.
Clearance expands each piece to represent real-use space, not just the legs or base. Add clearance when you need chair pull-back room, lid swing space, or safe distance from delicate beds. The calculator applies clearance consistently to rectangles, circles, and ellipses, giving a conservative layout allowance. For most patios, start with 0.05–0.20 m and adjust for traffic intensity.
Most furniture fits a rectangle, circle, or ellipse. Rectangles suit tables, benches, and storage boxes. Circles match round planters and fire bowls when you measure radius. Ellipses approximate oval tabletops and curved islands. For corner benches, L-shape mode subtracts a cutout from an outer rectangle to reflect the true occupied area. Use polygon mode for irregular bases such as built-in counters or angled shelving.
Total footprint area is most useful when compared to the available patio, deck, or lawn pad. Keep practical limits by leaving space for walkways and emergency egress routes. If the total consumes most of the site, reduce piece count, choose slimmer profiles, or lower clearance where movement is limited. Review both m² and ft² totals to align with regional drawings and procurement lists.
Layouts evolve with weather and usage. Exporting CSV supports quick auditing of sizes, units, and per-piece areas, while PDF creates a shareable snapshot for clients or site notes. Save records before and after adjustments so you can justify spacing decisions and replicate proven setups in other garden zones. Documented footprints support maintenance planning.
Use the footprint that touches the ground for stability checks. If people sit or pull chairs, add clearance to reflect the usable space around the tabletop and seating.
Start with 0.05–0.20 m for light circulation. Increase clearance near doors, grills, or high-traffic paths where turning and carrying items is common.
Use polygon mode and enter corner coordinates in order. This estimates area from the outline. Clearance is not applied to polygons, so include extra margin in your site layout.
Each calculation uses one dimension unit for all pieces to keep totals consistent. If your source measurements vary, convert them first, or run separate calculations and combine totals manually.
L-shaped benches and counters often leave an empty corner. The calculator models this by subtracting a rectangular cutout from an outer rectangle, which matches many modular designs.
Reduce the number of pieces, choose slimmer items, or reassign zones for storage versus seating. Keep essential walkways open and verify safe access to plants, utilities, and exits.
