Masonry & ConcreteFrequently Asked Questions
Is it free to embed these calculators?
Yes, completely free. No API key, no account, no usage limits. We just ask that you keep the small "Powered by BuildCalcPro.org" link at the bottom of each widget.
Can I customize the appearance?
The calculators automatically match most site designs. For more control, wrap the iframe in a styled container and adjust the width, height, and border-radius to fit your layout.
Will embedding slow down my site?
No. We use loading="lazy" by default, so the iframe only loads when a visitor scrolls to it. The calculators are lightweight and client-side — no heavy API calls.
Can I embed on WordPress, Wix, or Squarespace?
Yes. Any platform that supports HTML or "Custom HTML" blocks will work. In WordPress, use the "Custom HTML" block. In Wix, use "Embed a Site". In Squarespace, use a "Code Block".
