Versatile Slope Applications
Site Grading
Calculate precise slope ratios for site grading and earthmoving projects to ensure proper land contouring and preparation.
Foundation & Landscaping
Determine the correct pitch for foundation work and landscape features, preventing structural instability and soil erosion.
Drainage Planning
Plan effective drainage systems by estimating necessary percent grades for pipes and landscape runoff management.
Ramp & Driveway Layout
Check ramp and driveway slopes against safety standards and local building codes for optimal access and paving durability.
Slope Calculator FAQ
HOW DO RISE AND RUN RELATE TO PERCENT GRADE?
Percent grade is calculated by dividing the rise by the run and multiplying by 100. For example, a 1-foot rise over a 10-foot run results in a 10% grade. This measurement is commonly used in civil engineering and landscaping for drainage planning.
WHEN SHOULD I USE ROOF PITCH VS STANDARD SLOPE?
Roof pitch is typically expressed as a ratio of 'rise over 12' (e.g., 4/12), whereas standard slope is a simple ratio of rise to run (e.g., 1:3). Use roof pitch for architectural roof design and standard slope for general grading, ramps, or stairs.
WHAT ARE SAFE SLOPE RANGES FOR RAMPS AND DRAINAGE?
For ADA-compliant ramps, a maximum slope of 1:12 (8.3%) is required. For effective surface drainage in landscaping, a minimum slope of 2% (1/4 inch per foot) is usually recommended to prevent standing water and ensure proper runoff.
