As scale is based on a ratio, meaning 1mm on the page is always 50mm on the ground at 1:50 (Metric), you can use our calibration pages to scale plans where you know the scale, but have no dimension lines.
Disclaimer: Buildxact is not responsible for any plans that have been mislabeled with an incorrect scale.
1. Open and download the file corresponding to the measurement system you use (using the download button in the top right).
METRIC (eg: 1:100)
IMPERIAL (eg: 1 1/2" = 1'-0")
Note on paper size: in the past this article outlined the different paper sizes separately. To keep it simple, we've now changed to one page for both metric and imperial scales. The rationale here is that for metric, 1mm on paper will always be 1mm on paper regardless of how big the page actually is. Hence a scale of 1:100 will always convert 1mm on paper to 100mm on the ground, regardless of the paper size. Paper size is only used to ensure that a page is printed at the right size, which is important for manual measuring with a scale rule. The same logic applies to imperial scale.
2. Load your file into the Plans & Takeoffs section with the other page(s).
3. Hit the "Scale" button and select to "Scale all pages"
4. Choose the page uploaded in Step 1 as the basis of your scaling. Ensure you use the line which matches the scale you want. For example, the horizontal line for 1:50 (Metric) will be entered as 30,000mm.
Please contact us if the scale you need is not included on our calibration pages.
