Paste it and we'll try to pull the specs for you.

This can't read every site — some pages don't list specs in a way we can find, or only show them after you interact with the page, and it can occasionally pull in the wrong number or misread a spec entirely. Always double-check the fields above against the product page before ordering.

Frequently asked questions

Can I calculate wallpaper for more than one client at a time?+

Yes — the free calculator on this page works for a single room right now, no signup needed. The Designer plan adds a client list, so every room you calculate gets organized under the right client instead of getting lost in a single running total.

Can I send my client the specs directly?+

Yes. Designer includes a one-click "email specs to client" action that sends a clean summary of each room's dimensions, wallpaper, and roll count — no exporting or reformatting required.

Does it save the product details I looked up — brand, pattern, product link?+

Yes. Paste a product link from most wallpaper retailers and the calculator pulls the roll width, length, repeat, and match type automatically, then saves it alongside the room so you don't have to re-enter it later.

Do I need to upgrade to try it?+

No — the calculator above is free and doesn't require an account. Upgrade only once you want to save rooms, organize them by client, and send specs directly from the app.
