Measuring scale drawings

Question

HiI've received architectural drawings in PDF format, the scale on the drawing is listed as 1:100 on A1 size paper. I'm trying to take measurements using the measurement tool in Adobe Acrabat Reader DC, but after changing the Change Scale Ratio and Precision option to 1:100, I'm getting obviously wrong results. I've noticed that in the bottom left corner of the screen it shows '11.68 x 8.26 in' which, if represents the page size, isn't A1 paper size. Is this something to do with my issue? Any advice would be appreciated.

Hi bricktinter,Looking at the issue description, it seems the file may not have been converted properly. As the page size is not coming properly so the scaling proportionality won't come correctly. So you have to check according to the PDF size you have right now. If you already have figured a solution to this problem, please respond with your findings that will help others.-Tariq Dar.

In the measuring tools tab there is an option to calibrate measurement. Make sure you have a visible dimension in the drawing such as a dimension between grids then click the 2 points and type in what the measurement should be (with units) then you can get accurate measurements from the PDF drawing
