How to Find the Change Scale Ratio Option in Acrobat
Question details
The user needs to locate the 'Change Scale Ratio' command to adjust measurement scales in a PDF document, as it is missing from the main toolbar.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Measuring distances, perimeters, or areas in a PDF drawing or floor plan.
- Observed behavior
- The 'Change Scale Ratio' option is not visible in the primary Measure tools toolbar, preventing the user from adjusting the drawing scale.
Ensure you have a PDF document open that requires measurement and that the Measuring tool is active in your Acrobat workspace.
Access Change Scale Ratio via the Context Menu
Since the option is hidden from the primary toolbar, you can easily access it using the right-click context menu while the measuring tool is active.
Adobe Acrobat streamlines its main toolbar by placing advanced measurement settings, like the scale ratio, inside a context-sensitive menu. You must have a measurement tool currently selected for this menu to appear.
Open your PDF in Acrobat, go to the 'Tools' menu, and select 'Measure' to activate the measurement features.
With the measuring tool selected, right-click anywhere on the PDF page to open the measurement context menu.
Click on 'Change Scale Ratio' from the dropdown menu and enter the required drawing scale for your measurements (e.g., 1 inch = 10 feet).

Use WPS PDF to Measure and Set Scale Ratios
WPS Office provides a lightweight, easy-to-use PDF editor with built-in measurement tools. You can easily set scale ratios for accurate drawing measurements without searching through complex menus.
- 1. Open PDF in WPS Office: Launch WPS Office and open your PDF document containing the drawings or floor plans.
- 2. Select the Measure Tool: Navigate to the 'Comment' tab and click on the 'Measure' tool icon to reveal the measurement options.
- 3. Set the Scale Ratio: In the measurement settings panel that appears, directly input your desired scale ratio before taking your measurements on the document.
