How it works

  1. Pick your project

    A slab, a fence post, a room to paint. We draw it so you know which measurement goes where.

  2. Enter your measurements

    Feet and inches the way you'd write them on the job: 10' 6" works.

  3. Take the list to the store

    Bags, yards, boxes and gallons rounded up to what you can actually buy, with the cost. Print it or send the link.

Why YardaCalc

  1. No strings attached

    Many project calculators are lead forms in disguise. Ours never ask for your email, phone or address, and your measurements never leave your browser.

  2. Every number has a source

    Bag yields, coverage rates and prices come from manufacturer data sheets and published price surveys, linked with the date we checked them.

  3. Made for the trades too

    Contractor-friendly numbers and a Spanish version written in the words crews actually use on U.S. job sites.
