How to use this tool

  1. Enter required run length, stock section length, overlap per joint.
  2. Select Calculate to view the result.
  3. Check the method and assumptions below before using the result.

The method, explained

n sections cover n×stock−(n−1)×overlap. Solve for n and round up.

A WORKED EXAMPLE

Using required run length = 20 m, stock section length = 3 m, overlap per joint = 0.05 m, the result is 7 sections. Change these example inputs to match your task; use the method above to check each step.

Understanding your result

One straight run, no corners or downspouts. Check the actual connection system; some use zero overlap.

What to keep in mind

One straight run, no corners or downspouts. Check the actual connection system; some use zero overlap. A material-quantity estimate, not a structural design or building-code check. Confirm site measurements, supplier coverage and waste before ordering.

Common questions

How do I use this gutter section calculator?

Estimate stock gutter sections for one continuous run with joint overlap. Enter required run length in m, stock section length in m, overlap per joint in m. The starting example is editable; use values for the same system or project.

Which assumptions affect this result?

One straight run, no corners or downspouts. Check the actual connection system; some use zero overlap.
