Practical tools for everyday projects
ToolMix Lab brings useful calculations into a straightforward interface. The current collection includes thirteen construction and home improvement calculators: area, volume, tile, wallpaper, paint, concrete, drywall, grout, flooring, self-leveling compound, tile adhesive, lumber and gravel. Each has measurements you can enter yourself and assumptions you can inspect.
The calculators run in your browser. You can copy, download or print an estimate without creating an account. Optional drafts help you return to a plan on the same device.
Know what an estimate means
A calculator can make the arithmetic consistent while still depending on the quality of the inputs. Our tools show the basis of the estimate and describe what is excluded. They do not replace a site measurement, a product label or a detailed installation plan.
Read how we calculate for our approach to formulas, rounding and revisions. The project guides explain the decisions that a number alone cannot make.
