1:1 Drawings exporting inaccurately as PDFs

Hello! When exporting drawings as PDFs I have noticed that the 1:1 scale is around 4.4% smaller than it should be. First I thought it was an issue with the printer resizing the PDF after double checking the dimensions on the paper with calipers (76.6mm). Then I measured the same distance on my screen with the drawing opened at 1:1 ratio/actual size in Acrobat; Same dimensional error. I went back into the onshape drawing but inserting a dimension into the drawing yields a distance of 80mm, as it was designed to be.
I have tried exporting with as different PDF versions but nothing seems to help.
Anybody know what this could be?

I've run into this as well. I don't remember what I did to get around it? I may have exported DXF and imported into another CAD program. or just applied a scale factor to the print settings. Never really tried to narrow down the issue.
I ran into this on my Mac about 5 years ago, I forget if I have recently. I was printing full-scale and using the paper printout to cut shapes into sheetmetal. What I found was it was either the browser or print setting. Printing the pdf from the integrated browser on Firefox was bad, but then on MS Edge it was good. The other thing I found, was setting the scale in the printer dialog to "full" was bad, but manually typing in 100% was good.
This is from memory 5 years ago, so I might be a bit off. But I'd try all of these and see if one of them works.
