Grading, stormwater, planting, structural, lighting, and cost calculators built around the same codes and standards landscape architects and engineers already reference — from the Rational Method to ADA and AASHTO.
Calculators
Grading, hardscape, stormwater, planting, structural safety, lighting, carbon and more — covering the full site design process from concept to construction.
Converters
Everyday units plus specialist engineering, fluids, light, electricity, magnetism and radiology conversions.
Engineered for Precision
Rooted in documented architectural and engineering methodologies.
Frictionless Workflow
Replace clunky spreadsheets with real-time, browser-based parametric tools.
Committed to Open Access
No paywalls or accounts. Professional infrastructure tooling available to everyone.
CalcType grew out of a simple frustration: most landscape and site design math still happens in scattered spreadsheets, half-remembered formulas, and outdated PDFs. Each calculator on this site is built around a specific, named methodology rather than a generic estimate — cut-and-fill volumes follow standard earthwork practice, stormwater sizing follows the Rational Method, pavement structures follow AASHTO’s layered design approach, and accessibility checks follow ADA and equivalent international frameworks. The goal isn’t to replace a licensed engineer or landscape architect, but to give you a fast, transparent way to test design options — spacing, load, budget, drainage — before committing to detailed drawings or a formal cost plan. Every calculator sits alongside a written explanation of the method behind it, so the reasoning is visible, not hidden inside a black-box result.
These tools are provided for preliminary estimation and educational purposes. Results should be verified by a licensed Professional Engineer (PE) or Professional Landscape Architect (PLA) before construction, procurement, or permitting, since local codes and site-specific conditions can change the correct answer. CalcType is not liable for decisions made solely on the basis of these calculators.
