Top 6 PDF Measuring Tools

Based on the table above, we believe you already have a preliminary understanding of the five PDF editing software. Now, we will provide you with a detailed introduction to the measuring functions of these 6 PDF editing tools.

1. Acrobe Acrobat

You can use the 'Measure objects' tools to measure distances and areas of objects in PDF documents. The measuring tools are useful for showing the distances and areas associated with objects in the form of computer-aided design (CAD) drawings. You can also use these tools to measure certain areas of a document before sending it to a professional printer. The measuring tools are available to Acrobat Reader users only if the PDF creator enables measuring functionality.

When you use a measuring tool, the Measurement Info panel shows information about the measurement, such as current measurement, delta values, and scale ratio. Acrobat inserts comments with the values calculated for distance, perimeter, or area. 

2. PDF Reader Pro

It is a PDF editor that measures area, perimeter, height, length, or distance between shapes in PDF. You can set the drawing scale in the options section. All measurements are stored as editors in the PDF. With this free PDF measure service, you can calculate the area, perimeter, or distance between geometric shapes as in Computer Aided Design (CAD) PDF.

To measure an object, you can click “Editor” and choose “Measure”, then choose the measurement tool you wish to use, like Line, Multilines, Polygon, or Rectangle.
