Rolling Offset Calculator Calculate rolling offset, true offset, and travel length for pipe or conduit routing. — free online calculator.

Formula

True Offset = √(H² + V²); Travel = √(Offset² + Advance²); Setback = Offset / tan(θ)
  • Rolling Offset Calculator calculates its result from Height, Volume, Offset, Advance, Angle θ. It uses the formula True Offset = √(H² + V²); Travel = √(Offset² + Advance²); Setback = Offset / tan(θ). Change any input to recalculate the result instantly.
  • The main inputs are Horizontal Offset, Vertical Offset, Advance, Fitting Angle. Enter them in the units and format shown in the calculator.
  • Keep measurements and project assumptions consistent before comparing or combining values.
  • Changing any input above recalculates the result with the same calculation engine used by this page.

Example: Rolling Offset

Inputs
  • Horizontal Offset: 6
  • Vertical Offset: 8
  • Advance: 12 run
  • Fitting Angle: 45

Using Height = 2, Volume = 3, Offset = 4, Advance = 5, Angle θ = 6, the calculated result is -13.7454120167.
