When an author asks me for a quote, my first question is almost always how many spreads they have in mind. And the most common answer, by a wide margin, is a pause followed by “what exactly is a spread?”

It is a fair question. Nobody is born knowing publishing vocabulary, and the answer turns out to matter more than most authors expect, because it decides your page count, your printing cost, your illustration budget, and how your story feels when someone reads it aloud.

Here is the whole thing explained properly.

Open any picture book flat on a table. The two pages facing you, left and right together, are one spread.

That is it. A spread is a pair of facing pages, and it is the unit picture books are designed in, because it is the unit the reader experiences. A child does not see page eleven. They see the left and right pages together, as one image, until someone turns the page.

This is why illustrators talk in spreads rather than pages. An illustration might fill both pages edge to edge, sit on one side with text on the other, or be split into smaller images. All three are still one spread.

Picture books are almost always 24, 32, 40, or 48 pages. Thirty two is by far the most common.

This is not tradition or superstition. It is printing. Books are printed on large sheets that get folded and cut, and each folded sheet, called a signature, produces a multiple of eight pages. A 32 page book is four signatures. A 30 page book would mean paying for 32 pages and wasting two, so nobody does it.

The practical consequence is that you should design toward one of those numbers rather than discovering it at the printer. If your story naturally runs to 35 pages, it is going to become 32 or 40, and it is far better to make that decision yourself while writing than to have it forced later.

Here is where authors get tripped up, so let me walk through it slowly using a standard 32 page book.

Not all 32 pages are story. The front of the book takes some. You typically have a title page, a copyright page, and often a half title or dedication page. Together these are usually called front matter, and they commonly account for four pages.

That leaves 28 pages for the story, which is 14 spreads.

Some books use fewer front matter pages and get 15 spreads. Some place the copyright information at the back instead. Some use the very first spread as part of the story, beginning the illustration before the title even appears, which is a lovely effect when it suits the book.

So when I quote a 32 page picture book, I am usually quoting between 12 and 16 illustrated spreads depending on how the front matter is handled and whether any spreads are text only.

You can do this yourself in an hour, and it will tell you more about your book than any amount of rereading.

Print the manuscript. Get a pencil. Read it aloud at the pace you would read to a child, and draw a line every time you feel the reader should turn the page.

You will notice something immediately. Page turns are not neutral. They are the strongest tool a picture book has. A page turn creates a small pause, a beat of anticipation, and the best picture books use it deliberately. Put a question or a hint of danger at the end of a spread and the turn delivers the answer. Put nothing there and the turn does nothing.

Once you have marked your turns, count them. If you have 14 or 15, your manuscript is already close to a standard 32 page book. If you have 22, you either have a longer book or you have some spreads carrying too little, and both are worth knowing before you commission artwork.

Modern picture books are shorter than most first time authors expect. A typical range is 500 to 1,000 words for the whole book, and plenty of successful ones sit well under that.

Divide that across 14 spreads and you get roughly 35 to 70 words per spread. Read that number again if it seems impossibly small. It is not a mistake.

The reason is that in a picture book, the illustrations carry half the storytelling. If your text describes the room, the illustration has nothing left to do. If your text says the boy went inside, the illustration can show you that the room is enormous, that the walls are covered in clocks, and that something is watching from the corner.

Authors who cut their word count almost always end up with a better book, because they leave room for the pictures to speak. If you are sitting at 2,500 words, your manuscript is probably telling the reader things the artwork should be showing them.

A few shapes recur because they suit the medium.

The journey, where each spread moves the character to a new place, giving the illustrator a fresh setting every turn and giving the reader visual variety.

The repeated pattern, where a structure repeats with variation, often three times, before something breaks it. Children love this because they can predict the pattern and feel clever, and then be delighted when it breaks.

The single location with escalation, where everything happens in one room or one garden but the situation intensifies. Cheaper to illustrate, because backgrounds are reused, and often very effective.

If you are working to a tight budget, that last structure is worth serious consideration. A story set in one place with three or four characters costs meaningfully less to illustrate than one that visits a new country every spread, and it is not remotely a lesser book.

Spread count is the single biggest factor in what illustration costs, which is why I ask about it first.

A 12 spread book and a 24 spread book are close to double the work, and roughly double the cost. If your budget is limited, reducing spread count is usually a better decision than reducing the quality of each one. A tight 12 spread book that is fully realised will always beat a 20 spread book where the effort ran thin at the end.

This is a decision worth making with your illustrator rather than before you meet them. Send the manuscript, say what you are hoping for, and ask what shape they think it wants to be. It is one of the more enjoyable parts of the process, and it usually improves the story.

You do not have to arrive with a page plan. Plenty of authors send me a manuscript with no idea how it breaks up, and working that out together is a normal first step.

But if you have read this far, you now know more than most authors do when they start, which means the conversation will move faster and the quote will be more accurate.

Print your manuscript, read it aloud, and mark the page turns. Then send it over and let us see what your book wants to be.
