Material Quantity Calculators
Ordering materials is where a project either saves money or makes a second trip to the yard. These calculators turn measurements into order quantities — cubic yards of concrete, tons of gravel, boxes of tile, sheets of drywall, rolls of sod — and they all include a waste allowance you control. Coverage figures are typical industry numbers, and the page tells you when a product's own label is the better authority.
Quick answer: This category holds 17 free calculators. Each one takes your measurements and unit prices and returns an order quantity or cost estimate in your browser — nothing is uploaded and no account is needed.
