Latest update:
These tools cover yard upkeep and the safety checks that go with home projects. The topsoil calculator estimates cubic yards, tons, and whole bags from area, depth, and product density; the compost calculator does the same for garden and raised-bed amendments, adding optional cost and weight. Use both when ordering soil for a lawn or bed, and enter package or supplier values rather than assuming a density. Before elevated work such as roofing or exterior painting, the ladder safety calculator applies the 4-to-1 setup rule to plan extension ladder length, angle, and clearance. Geometry alone cannot certify a safe setup — follow the ladder manufacturer’s instructions and check site conditions. Browse the Construction & Home collection.

Frequently asked questions
- What is the 4 to 1 ladder rule?
- The planning worksheet uses a 4:1 height-to-setback geometry: for every four units of support height, the base is set one unit back from the wall. The entered extension above the support height is added to the sloped rail length.
- How is the purchase length rounded?
- The worksheet first rounds its feet-based planning length upward to one decimal place. Meter mode converts that value and rounds the meter display to one decimal place; the meter display is not a separately applied upward ceiling. The result remains planning geometry, not a ladder selection or safety approval.
- Does the calculator guarantee a safe setup?
- No. Geometry alone cannot determine a safe ladder, duty rating, setup, access method, or regulatory compliance. Site conditions and applicable requirements need qualified evaluation, and the page rejects inputs that would present a misleading result.
