m
Enter vertical offset in m.
m
Enter lateral offset in m.
°
Enter elbow bend angle in °.

Formula

true offset=√(rise²+roll²); travel=offset/sin(angle); advance=offset/tan(angle).
  • Use the units shown beside each field.
  • Results update automatically whenever you change an input.
  • Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
  • Ideal centerline geometry for equal elbows. Fitting takeout and pipe cut lengths are not included.

Example Calculation

Example inputs
  • Vertical offset: 3 m
  • Lateral offset: 4 m
  • Elbow bend angle: 45 °

Offsets 3 m and 4 m give true offset 5 m; 45° bends need travel about 7.071 m.

Frequently asked questions

How do I use this calculator?

Enter vertical offset, lateral offset, elbow bend angle. The result updates automatically. Use Reset to restore the example values.

What method does it use?

true offset=√(rise²+roll²); travel=offset/sin(angle); advance=offset/tan(angle).. Ideal centerline geometry for equal elbows. Fitting takeout and pipe cut lengths are not included.

Why might a rounded result differ?

The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.

Are my inputs saved online?

No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
