Estimates only
The results from the WallpaperCalc calculator are estimates for guidance only. They are based on the measurements you enter and standard calculation methods, but they cannot account for every real-world factor — uneven walls, alcoves, sloped ceilings, unusual pattern matches, or measuring errors.
Always confirm the number of rolls with your wallpaper retailer or a professional decorator before purchasing, especially for large or expensive projects.
Not professional advice
Nothing on this site constitutes professional decorating, construction, or purchasing advice. If in doubt, consult a qualified professional.

We do our best to keep the calculator accurate, but we make no warranties about the completeness or accuracy of the results. We are not liable for any loss arising from reliance on the calculator's output, including over- or under-purchasing wallpaper.
