Measure the height, width, or area of objects
Use the measuring 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 a form or computer-aided design (CAD) drawing. 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 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.
