    Step-by-Step Tutorial

    Calculating how much concrete you need for a triangle has never been easier. Follow these 3 simple steps to make the process seamless and efficient. Let's get started!

    1. Choose Your Settings

    Select your unit type, cost type (by bag or by the yard/meter), bag size, cost and desired waste amount. Your settings will be automatically saved for when you come back the next time.

    2. Choose Your Shape(s)

    We understand that many projects require multiple shapes or dimensions. Choose from a slab, footing, column, stairs, curb/gutter, circle/tube or any combination of them—it doesn't matter how many you have, we'll do the heavy lifting.

    3. Add Your Dimensions

    Once your shapes are added, input the dimensions that you've measured for each of them. After that, your results will be shown!

    Pretty easy, isn't it?

    Edit, Save and Repeat

    Now you can easily measure all of your concrete projects. Bookmark this page and your calculations will be here when you return. When you're done, reset the calculator and start with a fresh one.

    Concrete Triangle Formula

    For those who like to do the math by hand, or are curious as to how it's done, below is the formula used:

    The Formula: (Length × Width × Depth or Thickness) / 2

    How to Measure a Triangle

    Measuring a concrete triangle is surprising simple. It involves measuring the length, width and depth of your triangle (which is really just a slab cut in half). As you've likely already seen, you can use our handy triangle calculator above. If you still want to do it by hand, you can use the steps below. Let's begin!

    1. Length: Measure the length of your triangle. This is the length of the triangle on its longest side, although the side really doesn't matter, as long as the width side is different.
    2. Width: Measure the width of your triangle. This is the length of the shortest side of the triangle, or the side that isn't the one you measured in the previous step.
    3. Depth: Measure the depth of the triangle. This will be how deep you want the triangle to be.

    That's it! Now, you can take those measurements and plug them into the formula above and you'll have your estimations.
