Bicycle parking rack layout calculator

Calculate rack positions and bicycle capacity with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use rack positions and bicycle capacity to compare changes to your inputs. The method and limits below explain the scope.

Calculation method

Calculation method

Rack positions (count)

Linear rack positions with envelope width, interposition gaps and two end clearances; no aisle/access standard assumption.

Bicycle capacity (count)

Linear rack positions with envelope width, interposition gaps and two end clearances; no aisle/access standard assumption.

Unused run length (m)

Linear rack positions with envelope width, interposition gaps and two end clearances; no aisle/access standard assumption.

Symbols and units
a
Usable rack run length (m)
b
Bicycle envelope width per position (m)
c
Clear gap between positions (m)
d
End clearance each side (m)
e
Bikes per rack position (count)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • User-supplied measurements and assumptions; Linear rack positions with envelope width, interposition gaps and two end clearances; no aisle/access standard assumption. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
