Compare page size and a simple fit.
Select a document page, target paper and margin allowance.
A calculation, not a printer profile
The fit uses the smaller of available width ÷ document width and available height ÷ document height. The margin is an equal allowance you choose, not a measured printer limit. The whole document page is fitted, including any white space already in it.
A driver may use different non-printable margins, crop settings or automatic rotation. Confirm its preview and print one test. “Shrink oversized pages” usually prevents enlargement; the fit percentage here can be above 100% when the target is larger.
