How to Measure PDF Documents Online and Offline Quickly in 3 Ways

Measuring distances, perimeters, and areas in PDF documents has never been easier. Measure PDF drawings, diagrams, text blocks, and more, for an endless variety of uses. Read on to learn how to measure in PDF with different PDF tools.

Way 1. How to Measure PDF in UPDF

When it comes to measuring a PDF, you might think of using Adobe Acrobat or other mainstream PDF tools for this task. However, some of them require subscriptions to access this feature. Yet, some people might simply want to know the dimensions of the design in a PDF. In such a case, UPDF for Windows comes to the rescue. It is a comprehensive PDF editor that is also designed with measuring features. Follow the steps below to measure a PDF in UPDF:

Step 1. Download and install UPDF on your device.

Windows • macOS • iOS • Android 100% secure

Step 2. Open the PDF that you want to measure and click the "Comment" tab from the left pane of UPDF.

Step 3. There are three types when you're hovering on the Ruler icon:

  • Distance Tool: This tool provides information such as the distance of the specified region, details about the X and Y axis angles, scale ratio, and precision of the provided details. If you want to measure the distance between two points, choose this tool.
  • Perimeter Tool: This feature displays information regarding the distance, perimeter, angle, X and Y axis details, aspect ratio, and precision. If you want to measure a set of distances between multiple points, select it.
  • Area Tool: The area tool provides details including distance, area, angle, X and Y axis details, scale ratio, and precision. If you want to measure the area within the line segments that you draw, select it.

Step 4. In this user guide, we select the "Distance Tool". Simply choose it, click on the first point and then double-click on the second point. Then, UPDF will show you the distance. And this feature of UPDF also helps you to check the design of dimension in PDF.

UPDF is more than a PDF measure tool, it is an all-in-one PDF editor that offers a free trial. Elevate your PDF management experience akin to Adobe Acrobat by upgrading to UPDF Pro, now available at a 60% discounted rate.

Way 2. How to Measure in Adobe Acrobat (PDF Documents)

It's easy to measure lengths and areas of parts of your PDF document in Adobe Acrobat. You can use the 'Measurement Info' panel to read the measurement, delta values, and scale ratio of a section of the document. This tool can also be used to add comments with the distance, perimeter, or area calculations.

Here's a step-by-step guide for how to measure on PDF documents:

Step 1. Open your PDF document in Adobe Acrobat and select 'Tools', then 'Measure'.

Step 2. In the secondary toolbar, choose 'Measuring Tool' to show the Measuring toolbar and Measurement Info panel.

Step 3. Choose one of the options:

  • Distance tool (to measure the distance between two points on the document)
  • Perimeter tool (to measure the number of distances between two points on the document)
  • Area tool (to measure the area within a section of the document that you draw)

Step 4. If you choose the Distance tool, click the two points that you want to measure between, one after the other.

Step 5. If you choose the Perimeter tool, click each point that you want to measure, and when you get to the final point, double-click.

Step 6. If you choose the Area tool, then click each point on the area you want to measure, and when you've clicked all of them, click the first one again to complete the measurement.

With this Adobe measurement tool, you can choose to:

  • Snap to paths
  • Snap to endpoints
  • Snap to midpoints
  • Snap to intersections
  • Measure in increments of 45°
  • Cancel measurements
  • Delete measurements

Way 3. How to Measure in PDF Documents Online

If Adobe Acrobat isn't the tool for you, then you might want to try a measure PDF online tool like foxyutils. This tool, like Adobe, enables users to measure lengths, areas, and perimeters easily and accurately. What's more, this tool is far more affordable than Adobe software, costing less than UD$3 per month on an annual subscription.

Follow these steps to learn how to measure in PDF documents online with foxyutils.

  1. Open foxyutils and upload your PDF document.
  2. Before you begin measuring, you'll need to calibrate the page. Select 'Measure' in the toolbar, then choose 'Calibrate'. Add a known measurement by following the on-screen instructions that appear.
  3. Once your document is calibrated, you can measure distances by selecting 'Measure' and then choosing 'Distances'. Drag a line across the PDF where you want to measure, and when you release, the measurement will appear on the page and in the 'Totals' area on the right-hand side of the viewer.

What is PDF Measurement?

PDF measurement is the process of assessing the length of a line between two points, around a perimeter, or within an area. Just as you would be able to measure the distance between two points on a physical piece of paper with a ruler, a PDF measuring tool does this digitally. It'll perform area and perimeter calculations for you automatically. Using this, you can add an appropriate scale to shapes, diagrams, and floorplans on a PDF document. The alternative to digital measurement is to print, measure, scan, and convert the document - a long process!

Whether you're a graphic designer working on a new design or a real estate agent finalizing a floor plan for your seller, this tool is invaluable for many professions. From technical uses such as analyzing architectural plans and survey data to creative and educational uses such as product design and Math homework sheets, measuring is made simple and quick to do using PDF measuring tools.

But why is this better than measuring the old-fashioned way, with a pen and ruler?

Well, for starters, it's much, much faster. Once you've calibrated the measuring tool, you can measure pages and pages of a PDF document almost instantly, with just a click here and a click there. Secondly, it's much more common to have documents digitally stored now than in paper form. Imagine how frustrating it would be if an architect got sent some plans digitally, then had to print them off, measure the distances, scan the document, and then convert the scanned pages back into a PDF, all before sending them on to a colleague or client. This long process is hugely simplified with the aid of PDF measuring tools.

When Do You Need to Measure in PDF?

It can be useful to measure lines and shapes in PDF documents for a number of reasons.

One common example is floorplans. These need to have fairly accurate PDF measurements in order to be at all useful. Floorplan measurements can be useful for estate agents, letting agents, property investors, home buyers, architects, engineers, builders, tradespeople, interior designers, town planners, surveyors and many more.

Educational resources are another example of a type of PDF document that might need accurate measurements. For this reason, PDF measuring can come in handy for Math teachers, Geography teachers, Science teachers, PE teachers, Art teachers, and more. Whether creating homework sheets, lesson plans, or activities for kids to do in class, a PDF measuring tool is a fantastic addition to a teacher's toolkit.

Town planners might also use PDF measuring tools to assess the size of plots of land, forested areas, waterways, towns, and cities. These measurements can be used by those in historical preservation teams, ecology teams, and environmental management teams for important decisions about town planning.

There are many more uses for measuring PDF drawings even still: graphic design, agricultural planning, medical imaging, manufacturing, insurance claims, and event planning to name just a few.

The OCR feature

Optical Character Recognition (OCR) technology is another fantastic feature of UPDF. This technology converts images, like scanned documents, into text, providing a way for companies and individuals to digitize their paper documents. Once you've converted your scanned documents into text PDFs, you're able to edit and annotate them just like you would any other PDF document.
