Embed the Wallpaper Calculator

Drop a free, fully working wallpaper roll calculator into your blog post, product page, or design tool. It's the same tool used on our homepage — accounts for pattern repeat, straight vs. drop match, and lets visitors email themselves the result — wrapped up in one iframe. Popular with interior design blogs, wallpaper retailers, and installers who want a useful tool on their own site without building one.

Quick start

Paste this into your page's HTML wherever you want the calculator to appear:

<iframe
  src="https://wallpapercalculator.io/embed"
  width="100%"
  height="900"
  style="border: none; max-width: 480px;"
  title="Wallpaper Calculator"
  loading="lazy"
></iframe>

Sizing it to your layout

width="100%" makes it fill its container — pair it with a max-width(we suggest 480px) so it doesn't stretch too wide in a full-page layout.
height="900" fits the full calculator without an inner scrollbar on most screens. Narrower widths may need a slightly taller value since the form fields wrap.
The widget has no fixed minimum width, so it works in a sidebar or a full-width content block equally well.

This is exactly what your visitors will see and use once embedded:

FAQ

Is the embed really free?

Yes. The embedded calculator is the same free tool available on our homepage — no signup, no API key, and no cost to add it to your site.

Do I need to keep the “Powered by wallpapercalculator.io” link?

Please do — that attribution link is how we support hosting the free widget, and removing it isn't permitted. Everything else about sizing and placement is up to you.

Will it match my site's design?

The widget uses its own light/dark-aware styling so it looks clean on most backgrounds. It doesn't currently support custom theming or color overrides.

Can visitors email themselves the result?

Yes — the embedded widget includes the same “email me this result” option as the full calculator, so your visitors can save their numbers without leaving your page.

Will it slow down my page?

The iframe loads lazily (loading="lazy"), so it won't block your page's initial render or hurt your Core Web Vitals.

Prefer to just use the calculator yourself?
