How Do I Change the Scale in Adobe Acrobat Pro?

To change the scale in Adobe Acrobat Pro, you'll need to use the measuring tool and then right-click on the PDF to access the scaling options. Here's a breakdown of how to do it:

Steps to Change the Scale

1. Open your PDF in Adobe Acrobat Pro.

2. Select the Measuring Tool: Go to Tools > Measure. You might see different measuring tools (Distance, Area, Perimeter). Select the one that's relevant to your needs.

3. Right-Click to Access Options: Once a measuring tool is selected, right-click anywhere on the PDF document. This will open a context menu.

4. Choose "Change Scale Ratio and Precision": From the context menu, select "Change Scale Ratio and Precision."

5. Define the Scale: A dialog box will appear where you can define the scale.

   • Ratio: Enter the desired ratio. For example, if you want 1 inch on the PDF to represent 10 feet in reality, enter 1 for the PDF distance and 10 for the document distance.
   • Units: Select the appropriate units for both the PDF distance and the document distance (e.g., inches, feet, meters, millimeters).
   • Precision: Set the level of precision (number of decimal places) for your measurements.

6. Click "OK": After setting the desired scale and precision, click "OK" to apply the changes. Your measurements will now reflect the new scale.

Example

Let's say you have a floor plan in your PDF, and you want to set the scale so that 1 inch on the PDF represents 5 feet in the actual building.

1. Select the Distance measuring tool.
2. Right-click on the PDF.
3. Choose "Change Scale Ratio and Precision."
4. In the dialog box:
   • Set "PDF Distance" to 1 and the unit to in.
   • Set "Document Distance" to 5 and the unit to ft.
5. Click "OK".

Now, when you use the Distance tool to measure a wall on the PDF, it will display the actual length in feet according to your defined scale.
