| Scenario | Lot (m) | Angle | Aisle (m) | Stall (m) | Landscape / Loss (%) | Estimated spaces |
|---|---|---|---|---|---|---|
| Retail pad parking | 60 × 40 | 90° | 7.0 | 2.6 × 5.5 | 8 / 10 | ~180 (typical output) |
| Angled one-way aisle | 55 × 35 | 60° | 6.0 | 2.6 × 5.5 | 10 / 12 | ~145 (typical output) |
| Compact-heavy layout | 50 × 32 | 90° | 7.0 | 2.6 × 5.5 | 8 / 10 | ~120 (typical output) |
Parking yield is controlled by the lot envelope, stall dimensions, aisle width, and whether modules are single-loaded or double-loaded. Start by confirming the gross rectangle you actually can build, then reserve space for islands, walkways, ramps, and turning pockets. The calculator converts these deductions into an effective packing area so you can test options without redrawing every sketch.
Parking angle changes both stall pitch and stall depth. At 90 degrees, the pitch is close to the stall width and layouts are simple to count. At 60 or 45 degrees, the pitch increases because vehicles align diagonally, but aisles can be narrower and circulation can feel smoother. Use the angle selector to compare tradeoffs between fit, maneuvering, and driveway connections.
Deductions are handled with two percentages: landscape and circulation losses. Landscape covers islands, planting, walls, and pedestrian buffers. Circulation represents dead zones, end returns, cores, and internal roadways. The usable factor reduces the working area, then the model estimates how many full modules fit across the lot width and how many stalls fit along the lot length.
Most projects must reserve accessible bays and may plan EV-ready spaces. This calculator estimates targets as a percentage of the total spaces, then caps them within the standard pool so the counts remain practical. Treat the accessible value as a planning number only and verify the final requirement using local regulations, ramp grades, and the exact route to entrances.
Use total spaces for feasibility and density for benchmarking. Spaces per 1000 square meters helps compare alternative sites or redesigns. Average area per space reflects the combined impact of stall size, aisle sharing, and deductions, so it is useful for quick budgeting. When you move to detailed design, update dimensions to your jurisdiction, confirm turning templates, and refine edge conditions. For permits and operations too.
No. It provides a fast, planning-level estimate using standard geometry relationships and allowance factors. Final counts should come from a scaled layout that includes curbs, columns, ramps, and verified turning paths.
Use meters for all lengths in this version. Keep the same unit for every dimension so areas and densities remain consistent. If you prefer feet, convert all inputs to feet and interpret outputs using square feet.
Islands, walkways, and circulation consume area that cannot hold stalls or aisles. Applying deductions early prevents optimistic counts and helps you compare realistic options across different site constraints and landscape requirements.
Start with your typical vehicle class and circulation pattern. Two-way aisles are wider than one-way aisles used with angled parking. Confirm widths with your standards and local guidance, especially near intersections and ramps.
They are estimated as percentages of total spaces and treated as targets. The calculator limits them within the standard pool so totals remain feasible. Always confirm required accessible counts, aisle widths, signage, and proximity rules.
Small lot dimensions, large stalls, wide aisles, low usable factor, or single-loaded modules reduce packing efficiency. Try adjusting angle, module type, deductions, or stall sizes, then validate with a sketch that includes end returns.
