About MaterialsMath

What this site is for, who makes it, and what we do not pretend to be.

What this is

MaterialsMath is a set of construction and remodeling calculators that try to answer the question you actually have, which is not "how many square feet is my floor" but "what do I put in the truck".

Most calculators stop at an area. That is the easy half. The half that costs money is the one that turns an area into boxes, bags, sheets and sticks, at the sizes the store stocks, with a waste allowance that reflects how your particular job will be cut.

So every calculator here gives you a shopping list, publishes the formula it used to get there, and then points you at the next calculation your project needs — because a tiled floor is not one purchase, it is tile, backer board, screws, tape, two separate bags of thinset and a bag of grout.

What we are not

We are not a trade body, we do not certify anything, and we are not standing on your job site.

Where a number belongs to a published standard, we cite the standard. Where it is a typical trade allowance, we say so rather than dressing it up. Where the manufacturer's chart beats our arithmetic, we tell you to use theirs — that comes up on the grout and thinset pages and we would rather lose the argument than mislead you.

We do not review products, we do not run affiliate links, and nothing on this site is a recommendation to buy a particular brand. The site is funded entirely by display advertising, which means we have no reason to steer you toward one product over another.

How it is built

A static site: plain HTML, no framework, no tracking beyond analytics, no external fonts or scripts. It loads fast on a phone with one bar of signal, which is where a lot of people read it — standing in an aisle, working out whether eight boxes is enough.

Every calculator runs in your browser. Nothing you type is sent anywhere. There are no accounts and no newsletter.

Corrections

If a formula is wrong, an assumption does not hold, or a figure is out of date, tell us and we will fix it.
