eng.parking-space-ratio Calculator
Calculates parking space-to-floor-area ratio and evaluates against zoning requirements for a development site. Parking ratios typically range from 2–4 spaces per 1,000 sf for office; 4–6 for retail — zoning minimums and maximums bracket the acceptable range.
Inputs
Building Sqft
Two-dimensional surface extent (m²). For complex shapes, break into simpler sub-shapes and sum.
Land Area Sqft
Two-dimensional surface extent (m²). For complex shapes, break into simpler sub-shapes and sum.
Use Type
Reference formula or conversion factor shown for context.
Efficiency Pct
Useful output divided by total input, as a percentage. 100% is impossible due to losses (heat, friction, resistance).
Results
parking spaces needed
Sample size or count used in the calculation.
land area for parking (sq ft)
The computed two-dimensional surface area.
parking-to-land ratio
The proportional relationship between two quantities.
spaces per 1,000 sq ft
Reference formula or conversion factor shown for context.
use type
The classification or type assigned based on the inputs.
330 sq ft per space
Reference formula or conversion factor shown for context.
