Right-click the Document

With the measuring tool selected, right-click anywhere on the PDF page to open the measurement context menu.

3
Choose Change Scale Ratio

Click on 'Change Scale Ratio' from the dropdown menu and enter the required drawing scale for your measurements (e.g., 1 inch = 10 feet).

Access Change Scale Ratio via the Context Menu
Quick Access: Once the scale ratio is set via the right-click menu, all subsequent measurements on that page will automatically calculate using the new scale.
