Use the measured quantity first
Start with the drawing or a defensible site measurement. Keep geometry separate from product coverage, compaction, cuts and purchase rounding so each decision stays visible.
These tools estimate quantities. They do not choose structural sizes, verify code compliance or replace a manufacturer installation specification.
