Home & Construction

Home and construction calculators estimate the materials a project needs before you order. The concrete calculator turns slab dimensions into cubic yards, the gravel calculator and mulch calculator estimate bulk material by depth, and the square footage calculator measures the area you are covering.

For finishes and structure, the tile calculator counts tiles with a waste allowance, the roofing calculator converts roof area into squares after a pitch factor, and the stair calculator works out the number of risers and the actual riser height from the total rise. The BTU calculator gives a rough heating or cooling size for a room.

These are planning estimates. Real jobs need extra for cuts, breakage and uneven ground, and building codes set limits on things like stair dimensions. Check local code and your supplier's coverage figures before you buy, and use a licensed professional for structural or electrical work.
