The worst case scenario with PDF pages is lossy compression, so the “only” problem with PDFs with small page widths is page orientation. While not necessarily bad (as the lossy compression can be mitigated), some PDFs may be badly disoriented if pages are compressed too close together. The second worst case scenario is lossy compression, so page orientation is obviously no longer a problem. While some PDFs may have issues with page orientation (for example depending on whether they are monospaced or non-monospaced), in.
