# How to Publish Your Self-Illustrated Picture Book
## 1. Perfect Your Manuscript Most picture books run 500 words or fewer and span 32 pages. Write tight, read aloud often, and test the story with children. Every page turn should offer a small surprise or visual payoff. Remember that your illustrations can carry part of the story, so avoid describing what the art already shows.
## 2. Create a Storyboard and Dummy Sketch thumbnails of all 32 pages (typically 12–14 spreads plus front and back matter). Then build a physical or digital dummy to check pacing, text placement, and flow. Leave space for gutters, since the book's center fold can swallow important details.
## 3. Choose Your Publishing Path
**Traditional publishing:** Author-illustrators typically submit a complete manuscript plus a dummy and two or three finished sample illustrations. Query literary agents or publishers who accept submissions, and follow each guideline carefully. Expect long waits and rejections. The SCBWI (Society of Children's Book Writers and Illustrators) is an excellent resource for finding markets.
**Self-publishing:** You keep creative control and higher royalties, but you handle production, cost, and marketing. This route suits those who want speed or have a niche audience.
## 4. Prepare Final Artwork (Self-Publishing) Work at 300 DPI minimum, in CMYK or the printer's preferred color profile. Add a 0.125-inch bleed around each page. Choose a standard trim size such as 8.5 x 8.5 inches or 8 x 10 inches. Keep text and key art at least 0.5 inches from the edges.
## 5. Handle the Details - **Editing:** Hire a children's book editor or trade critiques with other writers. - **Typography:** Use readable, child-friendly fonts and strong contrast. - **ISBN:** Buy your own through Bowker (US) so you're listed as publisher. - **Copyright:** Register your work with the U.S. Copyright Office.
## 6. Select a Printing Platform Print-on-demand services like Amazon KDP and IngramSpark need no upfront inventory and offer wide distribution. For higher-quality hardcovers or bulk orders, consider offset printing, which lowers per-unit costs at larger quantities. Always order a proof copy and check color accuracy.
## 7. Market Your Book Build an author website and mailing list before launch. Reach out to school librarians, independent bookstores, and parenting bloggers. Offer reading events, classroom visits, and activity printables. Gather early reviews through advance copies, and consider a crowdfunding campaign to fund printing while building an audience.
## 8. Keep Creating Success in picture books often comes from building a catalog. Learn from sales and reader feedback, then start your next story.
With patience, polish, and persistence, your illustrated vision can reach young readers everywhere.

# How to Get Your Self Illustrated Picture Book Published
## 1. Finish Your Manuscript
Picture books are generally less than 500 words and have 32 pages. Write concisely and read it out loud many times. Test it on kids if possible. Want readers to be intrigued on each page. Don't describe what the illustrations are showing you can use them to help tell your story.
## 2. Develop a Story Board and Dummy
Do thumbnail sketches for your 32 pages. It will most likely be 12-14 spreads and additional cover/pages at the beginning and end. Make a dummy to see how the book flows. Allow space for the gutter because it will eat into your artwork when printed.
## 3. Decide How you Want to Publish
**Traditionally: ** Author-Illustrators usually send in their completed manuscript and dummy along with 2 or 3 full illustrations. You can query an agent or look for markets that take submissions. Make sure to read the submissions guidelines. It may take some time to get your book published and you may get many rejections. There are many market lists available on the SCBWI site.
**Self: ** When self publishing you can publish as soon as you'd like and will receive more profit from sales. But you will have to pay for the production and find ways to advertise your book.
## 4. Finish Your Illustrations
If you are self publishing make sure your images are high quality (minimum 300dpi). Use Cmyk and give a .125 bleed. Make your book the appropriate size. Some sizes are 8.5x8.5 or 8x10 inches. Keep everything .5" away from the edge of your book.
## 5. Finishing Touches
- Have your book edited or swap with another writer.
- Make sure your font is legible.
- Get your ISBN from bowker.com this will allow you to be the publisher.
- Copyright your book through the Copyright Office.
## 6. Find a Printer
Amazon KDP and Ingrams Spark will print your book on demand and give you access to distribute your book. If you want to order many at once you can try offset printing. Order a proof from whichever company you decide to use and make sure your colors look correct.
## 7. Advertise Your Book
Create a website and mailing list before your book is published. Contact local school librarians, book stores and blogs. Do school programs and create fun activities that can go along with your book. You can also get your book reviewed before its released. Some people choose to crowdfund their books which is a great way to finance the cost of printing.
## 8. Work On More Books
Once you have one book published continue to write and publish more books!

## 1. Perfect Your Manuscript Most picture books are under 500 words and are 32 pages long. Write succinctly, read aloud frequently and do test the story with children. There should be a little surprise or payoff on every set of page turns. Keep in mind that art should tell some of the story; don't explain what the artwork already depicts.
