HOW TO USE THESE GUIDES
Measure first. Use product data second. Round for real purchasing.
1
Measure the project
Good estimates start with dimensions that match the surface, volume or run you are actually building.
2
Use the real product
Coverage, yield, pack size and density vary. Manufacturer or supplier values beat generic assumptions.
3
Plan the purchase
Convert the mathematical result into full bags, boxes, boards, rolls or delivery units you can actually buy.
