Why this site is different

No mystery numbers.

Geometry first

Net area or volume is shown separately from waste, coverage, density, or package rounding.

Assumptions exposed

Board width, bag yield, supplier density, material coverage, spacing, and prices are user-editable.

Purchase-ready results

Bags, boards, sheets, and other purchasable units round up instead of leaving you with impossible fractions.
