Builders-Tools is a set of free calculators for the questions that come up before every project: how many bags, how many yards, how many sheets, how many posts.
What makes it different
- A real shopping list. Every calculator ends in a list you can print and take to the yard.
- A project list. Save results from different calculators into one list on your device, then print it all at once.
- Sources on the page. Factors come from the people who make the materials, with links.
What it is not
It is not engineering. Footings, retaining walls, beams and anything holding up a building need plans, and often a permit. Use these numbers to estimate and shop, and check structural work with a pro or your building department.
