How To Write And Self-Publish A Children's Book In The UK

A picture book is around 500 words and 32 pages, which sounds easy right up until you try it. The writing is the short part; illustration, layout and distribution are where the work lives.

Self-publishing in the UK is genuinely accessible now. Here is the whole route, with real costs.

Honest note: we make cards, prints, pin badges and party decorations in the UK. Publishing platforms, software and laptops are recommendations from elsewhere.

Step one: write it

• Picture books run 300 to 800 words across 32 pages, including endpapers.
• Write to the page turn - each spread needs a reason to turn over.
• Read it aloud to an actual child. They will tell you the truth immediately.
• Portability is the whole trick with writing. A light, all-day-battery laptop like a MacBook Air means drafts happen in cafes and waiting rooms instead of never.
• Rewrite it at least five times before anyone illustrates anything.

Step two: illustration and layout

• Hiring an illustrator in the UK typically costs GBP 1,500 to GBP 5,000 for a full picture book.
• If you illustrate it yourself, work at 300dpi with bleed and keep layers tidy - these files get big.
• Lay out in Affinity Publisher or Adobe InDesign, not in Word.
• Leave space in the artwork for text. This is the most common beginner mistake.
• Get a proof copy printed and read it as a physical book before publishing.

Step three: publishing

• Buy ISBNs from Nielsen - single ISBNs are expensive, blocks of ten are better value.
• Amazon KDP and IngramSpark both print on demand; IngramSpark reaches UK bookshops properly.
• Send a copy to the British Library legal deposit, which is a legal requirement.
• Typical UK picture book retail is GBP 7.99 to GBP 12.99 - work backwards from print cost.
• Set up as a sole trader with HMRC if you are selling copies yourself.

Step four: selling it

• Local independent bookshops and school visits sell more copies than social media will.
• Library reading sessions, which are free to arrange and put the book in front of parents.
• Craft fairs and Christmas markets, especially with a signed copy.
• Cards and prints from the book's artwork as a second product line.
• Start a greeting card business with the same artwork - Read the guide

Frequently asked questions

How much does it cost to self-publish a book in the UK?

A picture book usually runs GBP 2,000 to GBP 6,000 once illustration, editing, ISBNs and proofs are counted. A text-only book can be done for a few hundred.

How long should a children's picture book be?

Around 300 to 800 words across 32 pages. Anything longer belongs in an early-reader format instead.

Do you need an ISBN to self-publish in the UK?

You need one to sell through bookshops and libraries. UK ISBNs come from Nielsen, and buying a block of ten is far better value than single numbers.

Is Amazon KDP or IngramSpark better for UK authors?

KDP is simpler and pays better on Amazon sales. IngramSpark distributes properly to UK bookshops and libraries. Many authors use both.

How do you sell a self-published children's book?

School and library visits, local independent bookshops, craft fairs and markets. In-person selling beats social media for picture books.

Do you sell laptops?

No. We design and print greetings cards, enamel pin badges, prints and party decorations in the UK. Laptops and software are recommendations from elsewhere - the only things linked to our own shop are ours.
