font size problem in kobo, but not in calibre

[marp68]

Looking at the book in Calibre, the general text use the same font size, but when opening it in the device, sometimes some parragraphs are with slightly smaller fonts. Strange.

Why can that be? And how can I repair it with calibre, since everything seems fine in calibre?

I think all it can be is that the publisher has used different styles for the different paragraphs. There are a number of reasons why it could show up on one device and not another: for example if the difference in font-sizes is very small then they might round to the same pixel size on a low resolution device but to distinct pixel sizes on a higher resolution device; or if the publisher has mixed incompatible units such as 10pt in one paragraph and 1em in another paragraph then the sizes might be the same on devices where the settings happen to result in 1em=10pt but different on others where that coincidence doesn't occur;

The only way to see for sure what the publisher has done wrong would be to look at the html and CSS stylesheet for the paragraphs in question and see what styles are being applied. E.g. in Calibre use unpack book or edit book to examine the html/css files.
