Track Lane Distance Calculator
Estimate outer-lane lap distance using your base lap, equal lane width and lane number.
Base lap 0.000001–10⁶ m; width 0.100001–100 m; lane integer 1–1000. Assumes two semicircular bends and equal lane widths, with measurement lines 0.30 m from the kerb for lane 1 and 0.20 m from the inner line otherwise. Lane 1 adds zero. This estimate does not determine official surveyed stagger marks.
Δ = n = 1 ? 0 : 2π × ((n − 1) × w − 0.10); lap = L + Δ; bend = Δ / 2
Inputs stay in this browser. Values shown use at most 6 decimal places; money uses 2, in the currency you entered. Counts round upward.
