SlabCalc – Concrete Calculator Widget

설명

SlabCalc adds a free, embeddable concrete calculator to any WordPress page or post using a simple shortcode. Visitors can estimate how much concrete they need for slabs, driveways, and patios — in cubic yards, cubic feet, or cubic meters — without leaving your site.

What it does:
* Calculates concrete volume and bag counts instantly
* Supports slabs, driveways, and patio projects
* Works in imperial (feet/inches) and metric (meters/cm)
* Includes material cost estimates
* Mobile-responsive, no setup required

Usage:

Add the shortcode to any page or post:

[slabcalc]

Or specify a calculator type:

[slabcalc type="driveway"]
[slabcalc type="patio" width="400px"]
[slabcalc type="slab" theme="dark"]

Shortcode attributes:

  • type — Calculator type: slab, driveway, patio, or tube (default set in Settings)
  • width — Widget width, any CSS value (default: 100%)
  • theme — Color theme: light or dark (default: light)

FAQ

What shortcode attributes are available?

type (slab, driveway, patio, tube), width (any CSS value), and theme (light, dark).

Do I need an account to use this plugin?

No. The widget is completely free and requires no account or API key.

Will this slow down my site?

The widget script loads asynchronously and only on pages where the shortcode is used. It has no impact on pages without the shortcode.

Can I use multiple calculators on the same page?

Yes. Place [slabcalc type="driveway"] and [slabcalc type="patio"] on the same page and both will render. The embed script is loaded only once regardless of how many shortcodes are on the page.

Does it work with page builders?

Yes, any page builder that supports WordPress shortcodes (Elementor, Divi, Beaver Builder, Gutenberg shortcode block) will work.
