About this plugin
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 )
