Book template as PDF is DPI should be used estimate or 300dpi? first gives 196dpi and material company needs at 300dpi. is better

import it 196dpi and convert affinity publisher project then 300dpi. is guide lines only and some text elements (what tell what what guides mean and how do some elements). i think which way i get more correct end pdf size.

If you know the DPI you need, why not just  specify it rather than using Estimate?

i get exact same looking document and i used such way. oddly dimensions differ little (Acrobat reader shows them exactly) makes me wonder what makes this happen? its somekind rounding error. i hope its not too much company what book template i try use becouse i found making book cover from empty with their instuructions is not so easy when i cannot use different guideline colours of course i can use master page and draw things to it to get guides as solution.

i hope this goes well. becouse pages have only vector elements becouse i add own elements (vector elements are markings of things what are removed final pdf when i export it)

i found what goed wrong and how fix it. wrong is strong word of course and not exactly describe what happens. but wrong when i expect page size of 21x21cm for example not about 21.59cmx21.59cm is imported also bleed area as part of page.
then i need redesign bookcover becouse differencies given values is rounding only nothing else (difference is so little) and seems be level what is not problem but i tell later when i tested this service. not hard when current content of cover is easy redo.
