Design the pages your readers hold

Formatting a book for print usually means a second program, a second file, and a second learning curve. In Verkilo, interior design happens next to the manuscript it belongs to.

Trim sizes & margins

Choose from eleven trim sizes, including the standard UK formats, and set your margins from there. The gutter widens automatically as your page count grows, so the text never crowds into the binding on a long book.

A preview you can trust

The live preview runs the real export engine — the same one that produces your final print PDF. You are not looking at an approximation of your book; you are looking at its pages.

The polish carries into the ebook, too. Drop caps and opening small caps from your interior design come through in EPUB with safe fallbacks, and every EPUB is checked automatically before export — packaging, structure, and internal links — so you never upload a broken file unknowingly. One file, accepted by Amazon, Apple, Kobo, and Barnes & Noble.

Typography by genre

Readers feel type before they read a word of it. A romance page should read soft; a thriller page should be tight and invisible; an epic fantasy earns its inscriptional capitals. To show what that means in practice, we set the same specs a designer would use — trim, text block, face, size, and leading — for five fiction genres, at actual size.
