Affiliate Disclosure

MaterialWhiz may use affiliate links to recommend products, tools, or suppliers that are relevant to a calculator result. If you click one of those links and make a purchase, MaterialWhiz may receive a commission at no additional cost to you.

How recommendations work

Recommendations should be connected to the material, pack size, coverage, or tool discussed on the page. Affiliate relationships do not determine the calculator result, the formula, or the editorial conclusion. We do not promise that the lowest price, best availability, or a particular retailer will apply to every location.

What we disclose

We place a short disclosure near commercial recommendations and link to this page from the footer. Product information, prices, stock, delivery fees, and local rules can change, so confirm details with the supplier before ordering.

Advertising

MaterialWhiz may also display advertising. Ads are separate from calculator results and editorial recommendations. We do not ask users to click ads, and we do not change calculation results because of advertising relationships.

If a recommendation, disclosure, or calculator assumption is unclear, please use the Contact page.
