Material Planning Guides

Practical notes for the gap between a measurement and a purchase.

A material checklist and measuring tools

Project lists

From Net Quantity to a Shopping List

Follow a measured quantity through a chosen allowance and whole-pack rounding, and learn what to check on the final shopping list.

Read the guide

Start with a measurement you can trace

Learn how to record openings, separate surfaces and keep units attached to dimensions. A clear input is more useful than a long result with no explanation.

Understand the purchase quantity

Read about allowance, whole-pack rounding, product coverage and supplier units. These guides explain decisions you can check with your own project and product information.

Check before you buy

Use the final-order checklist to compare your measurements, specifications and exports. The tools prepare quantities; they do not place orders or choose a construction specification.
