For contractors, suppliers and publishers
Put a Drywalls Calculator calculator on your own site
Drywall contractors, supply houses, remodelers and DIY writers can put any of these calculators on their own pages. Copy the code, paste it where you want the calculator, and keep the one-line credit under it. That is the whole deal.
Who uses it
A drywall contractor's website with the sheet calculator or the cost estimator lets homeowners size their job before they call, and arrive with realistic numbers. A supply house can put the joint compound or screw calculator next to the product, so customers buy the right number of pails and boxes. Remodeling and DIY blogs use the drying time, finish level and repair patch calculators to answer the questions their readers ask.
How it works
The code loads the calculator from our site inside a frame, so it stays up to date when we fix or improve it, and it never touches your page's own styles. It needs no account, no key and no script of yours. The frame is 980 pixels tall by default; change the height value if your page needs it shorter or taller. Visitors who want the formula, the assumptions or the worked examples follow the credit link to the full page.
The terms
- Free for any website, including commercial ones, with no limit on visitors.
- Keep the credit line and its link under the calculator; you may restyle it, but not remove it or make it invisible.
- Do not present the calculator as your own work, and do not frame it inside advertising that could be mistaken for part of it.
- We may change a calculator's inputs or layout when we improve it. If you need a frozen version, write to us.
