Is it possible that these e-books, with too big pages, are PDF-files?

In that case there is not much to do about this, except using the e-reader to zoom in or out or use the PDF re-flow function if your e-reader supports that. Or the books are broken. Try to find/buy/download the book again and/or in a different format. Contact the book seller and complain and request a fix or a refund.

About line spacing.
Calibre has very powerful function for converting books. While converting you can adjust line spacing and a lot more. When I "fix" books I usually rip out most of the embedded font information and formatting. And I end up with almost plain text. And I can use my e-reader to select font, line spacing and size. And everything re-flows to fit.

Sometimes it is even possible to convert PDFs, if they are just plain text PDFs, but usually the result is gibberish.

Sometimes the book is a bad conversion from PDF, or some other format, and you might use calibre conversion to improve it. Convert lines to paragraphs and fix hard page breaks, chapter breaks, headers and footers and so on. But it is difficult and time consuming to get everything right.

The conversion can also be used to scale some parts of books, for instance images. You just need to select the right output profile in the page setup for the conversion.

It might be best to first convert to epub, without any changes. Then convert from epub to epub, with changes. And finally convert back to a format you can use on your e-reader, from epub without changes.
