Turbine Spacing Calculator
Calculate optimal inline and crosswind distances between wind turbines based on rotor diameter and layout factors. Reduce wake losses, optimize land use, and plan efficient wind farm arrays.
Input Parameters
Adjust values to compute spacing and layout.
Recommended: 7D – 10D for onshore, up to 12D offshore.
Recommended: 3D – 5D depending on wind direction variability.

Rotor Diameter Basis
Spacing is expressed as multiples of rotor diameter (D) to scale across turbine sizes.
Wake Losses
Proper spacing reduces energy loss from upstream turbine turbulence, typically 5–15%.
Annual Energy
Estimated using rated power, capacity factor, and wake-adjusted availability.
Frequently Asked Questions
Common questions about turbine spacing and wind farm layout.
How far apart should wind turbines be spaced? ▼
Wind turbines are typically spaced 5 to 10 rotor diameters apart in the prevailing wind direction (inline) and 3 to 5 rotor diameters apart perpendicular to the wind (crosswind). A common rule of thumb is 7D inline and 5D crosswind to reduce wake losses while keeping land use efficient.
Why does turbine spacing matter in a wind farm? ▼
Turbine spacing affects wake losses — the reduction in wind speed behind an upstream turbine. Too close and downstream turbines produce less energy; too far apart and you waste land and increase cable costs. Proper spacing balances energy yield, infrastructure cost, and available area.
How do you calculate turbine spacing from rotor diameter? ▼
Multiply the rotor diameter by the chosen spacing factor. For example, a turbine with a 120-meter rotor and a 7D inline factor gives 840 meters of inline spacing, while a 5D crosswind factor gives 600 meters between rows. Multiply rows × columns to estimate total farm area.
