- Use a WordPress Calculator Plugin
Install a plugin like Formidable Forms, Calculated Fields Form, or WPForms.
These plugins let you create forms with input fields and apply formulas to calculate values dynamically.
- Create Input Fields
Add fields for dimensions depending on the shape (e.g., length, width for rectangles, radius for circles).
Example:
Rectangle: Length (L), Width (W)
Circle: Radius (R)
- Add Calculation Logic
Use the plugin’s built-in calculation functions.
Example formulas:
Rectangle: Surface = L × W
Circle: Surface = π × R²
- Style the Calculator
Customize the look using your theme's CSS or plugin styling options.
Ensure it’s responsive and accessible on mobile devices.
- Publish the Calculator
Embed the form on any page or post using a shortcode.

Thanks for sharing this! I’ve used Formidable Forms before, and it’s a solid choice for building custom calculators. Just a tip: if you're working with different units (like meters vs. feet), make sure to include a unit selector or clearly mention the unit in the labels to avoid confusion. Also, testing the calculator on mobile is super important — a lot of users will be accessing it that way.
