Terms and estimating limits
Use the tools as planning aids and confirm the assumptions before ordering materials.
What the tools provide
These tools convert user-entered measurements and specifications into estimated material quantities. They do not provide a survey, installation design, product suitability decision, professional quotation or guarantee that a quantity will be sufficient.
Your inputs and products
Confirm dimensions, units, product coverage, package size, pattern match, allowance and owned stock. Product instructions and qualified advice for your particular work can change the order you need. The site cannot inspect surfaces, stored paint, damaged packs or matching batches.
Costs and files
Optional costs cover the entered material packages only. Tax, delivery, labour and other supplies are not included. A currency label does not perform a conversion. Check exported files against the current project and keep private backups securely.
Content and reused software
Examples are synthetic. Brand names on cited sources belong to their owners and do not imply sponsorship. The actual reused software has its own MIT notices on the open-source credits page. Site content and source references should retain their context and limitations.
Corrections
Report a reproducible problem. If an estimate looks inconsistent, pause the purchase and check the arithmetic and product label.
