There are weird differences between publishers in different countries.

In Poland there is this weird contest of making books largest possible. Mandatory points are huge font, enormous margins, huge spaces between paragraphs and chapters always starting from new page. Preferably with some graphic on half of such starting page. Magnified if it's a children's book. Also polish stylistics use new line for each character speaking so short conversations can take many lines.

It is shocking when you take same book released in UK or US. It looks like at least cut in HALF and actually much easier to read.
