Home and garden calculators

The complete home hub, built silo by silo. Landscaping materials came first, because that is where the easy wins and the spring demand are.

How to measure for any of these tools

Nearly every home calculator starts from the same three numbers: length, width and, for anything loose or poured, depth. Measure in feet and convert inches honestly. Six inches is half a foot, and depth is where most under orders are born, people eyeball it at half what it really is.

Walk the space instead of guessing from the porch. A 100 ft tape costs little and pays for itself the first time it prevents a second delivery fee. For beds and lawns with curved edges, measure the longest and widest points, calculate as a rectangle, and let the waste allowance absorb the curves.

Coming next in this hub

Concrete and hardscape, interior finishing, exterior and structures, project cost estimators, and sizing (BTU, generator, wire and voltage drop). Each silo ships only when its pages meet the same standard: working tool, formula on the page, a worked example, and a shopping list output.

Home project FAQs

How do I measure an irregularly shaped yard or bed?

Split it into simple shapes you can measure, rectangles, triangles and circles. Calculate each piece on its own and add the results. For a circle, square the radius and multiply by 3.14. Then add a waste allowance at the higher end, around 15 percent, because curves and corners eat material in cuts.

Should I buy materials in bags or in bulk?

Bags win on tiny jobs, a few cubic feet to patch or fill. Bulk wins sooner than most people expect: past about 2 cubic yards, a single delivery is usually cheaper than the same volume in bags, and it arrives in one pile instead of fifty sacks to open. The dirt calculator shows both numbers side by side so you can see the crossover for your job.

How much extra should I order for waste and settling?

Ten percent is the working rule for most home projects. Drop to 5 percent on a perfect rectangle with no cuts, rise to 15 percent on curves, slopes and compacted fill. Every calculator here has the allowance as a visible field, set to a sane default, never buried in the math.
