About this calculator

This estimates materials for a standard K-style gutter job: gutter sections (sold in 10-foot lengths), downspout footage, hangers spaced along the run, and end caps. Add roughly 10% extra material for waste and mis-cuts on a real job, this calculator does not include that buffer automatically.
