How do I measure distance in a PDF using the Measure Tool?

Open your PDF and select the Measure Tool. Choose the 'Distance tool'. Click on your starting point, then click on your ending point. Acrobat will show the distance between these two points.

What is the difference between the Distance, Perimeter, and Area tools in Acrobat's Measure Tool?

Tool Name What it measures How to use it. Distance tool Measures the length between two specific points. Click a start point, then click an end point. Perimeter tool Measures the total length around the outside of a shape. Click multiple points along the edge, then double-click to finish. Area tool Measures the total surface inside a closed shape. Click multiple points to draw the boundary of the region you want to measure.

How to do it

the tool · the steps · what to avoid

1
Open your PDF drawing in Adobe Acrobat.
2
Select the Measure tool from the right pane or from the Tools menu.
3
In the secondary toolbar, click the Measurement Tool options (gear icon or right-click in the drawing area).
4
Choose Change Scale Ratio from the context menu.
5
In the Change Scale Ratio dialog, enter your custom scale (for example, set '1 inch = 10 feet').
6
Click OK to apply the new measurement scale.

In the appWith the API

After setting your custom scale, all subsequent measurements will use the real-world units you specified.

This runs in the Acrobat app - there is no separate API for this task.

Geospatial PDFThis is a special PDF that contains location data, allowing it to measure real-world distances and areas automatically.ExampleAn engineer uses a geospatial PDF to measure the exact distance between two points on a construction site map.

Measurement ScaleThe measurement scale sets how units on the PDF relate to real-world units, like 1 inch equals 10 feet.ExampleThe measurement scale is set so that 1 inch on the map equals 1 mile in reality.

Page UnitsMeasurements shown in the size of the document page itself, like inches or centimeters on the paper, not real-world distances.ExampleThe document properties show the page is 8.5 by 11 inches, not the actual paper size.

about this task

Acrobat will show the distance between these two points.

A geospatial PDF is a PDF that has real-world location information built into it. This matters because when you use the Measure Tool on a geospatial PDF, Acrobat can automatically give you true ground measurements, like actual miles or meters. You do not need to set a scale manually, which makes measuring maps and plans much easier and more accurate.

If your PDF is a scanned image, it is very important to set the measurement scale correctly. Find a known distance on the drawing (like a marked wall length). Use the Measure Tool to measure that known distance on the PDF, then tell Acrobat what that distance should be in real life. This sets the scale for the whole document, making all other measurements accurate.

Your measurements are in page units because you likely have not set a measurement scale. Acrobat needs to know how the size on the page relates to real-world sizes. To fix this, you must set the scale (e.g., 1 inch = 10 feet) in the Measure Tool's settings. Once the scale is set, your measurements will show in the correct real-world units.
