Preview
The preview shows how the calculator sits inside your page. It’s fully interactive once embedded.
Add it to your site
- In the block editor, click + and add a “Custom HTML” block where the calculator should go.
- Paste the embed code into the block.
- Preview the page, then update or publish.
Menu names change from time to time; if yours looks different, look for an “HTML”, “Code” or “Embed” block.
Sizing and phones
- Fills the width you give it, up to 760 px, and works down to 320 px.
- The resize script adjusts the height as visitors use it, so there’s no inner scrollbar.
- Without the script it still works at the height in the code; leave the script in when you can.
- On phones the steps stack and the drawing gets compact, just like on CalcBrite.
What your visitors get
- The inputs, the answer and the to-scale drawing, plus bags or delivery where you choose it.
- No supplier search, ads or pop-ups inside the calculator, so it never sends your visitors to competitors.
- No account, cookies or sign-up. Visitors’ numbers stay in their browser.
- A small “Powered by CalcBrite” line at the bottom, and a one-line credit link under the calculator.

Questions
Is it really free?
Yes. There’s no fee, subscription or account, and no limit on the number of pages you use it on or how many times your visitors use it.
Is there a link back to CalcBrite?
Yes, one short line. The code ends with a credit under the calculator, such as “Ice Melt Calculator by CalcBrite”, linking to the full calculator, and the calculator shows a small “Powered by CalcBrite” line at the bottom. Please leave both in place; you can restyle the credit line to match your site.
Will it show my competitors?
No. Embedded calculators leave out CalcBrite’s supplier search, so visitors stay with you.
Can you match it to my site?
Yes, we’re happy to help. Tell us what you have in mind: email hello@calcbrite.com with the subject “Customization”.
