How to Calculate Gutter Length

Formula

Total Length = Front + Back + Left Side + Right Side

Sections = ceil(Total Length / Section Length)

Downspouts = ceil(Total Length / Max Spacing)

Measure every roof edge that needs a gutter. Standard residential gutters are 5 inches wide (K-style) and sold in 10-foot sections. Each run of gutter should have a downspout no more than 40 feet from the end or high point of the run.

Slope

Gutters must slope toward the downspout at about 1/4 inch per 10 feet of run. For runs longer than 40 feet, slope from the center toward downspouts at each end.

Ejemplo Resuelto

A ranch home with 50 ft of gutter on front and back, no side gutters, 10-ft sections, and 40-ft downspout spacing.

  1. Total gutter = 50 + 50 + 0 + 0 = 100 ft
  2. Sections = ceil(100 / 10) = 10 sections
  3. Downspouts = ceil(100 / 40) = 3 downspouts
  4. No corners needed for straight runs
