Instagram for illustrators: show your images, your books and the way you draw
For an illustrator, Instagram is often the first place where a publisher, an agency or an art director discovers your line. The images are already in your portfolio, sorted by project; what is missing is the time to crop them, caption them and post them without breaking the look of your profile. Here is what works for an illustrator, and how to keep it up without losing your evenings.
What an illustrator can post
- The project as a carousel: the cover or the key image, then the pages or applications. Up to 10 images, and the first one does all the work.
- The detail: a character, a texture, some lettering in close-up. A single image, a few weeks after the carousel, brings the project back to life.
- The process: sketches, pencils, colouring. Shown in order, they tell how you work.
- The printed object: the open book, the poster in the street, the packaging on the shelf. They show that your work exists off the screen.
- The Reel: a vertical video that runs through the project's images. On accounts under 10,000 followers, a Reel reaches 4.9% of followers, against 3.5% for an image (Fanpage Karma, August 2026).
The right format for an illustration
In the feed, Instagram shows images in 4:5 portrait (1080 × 1350 pixels); the profile grid only shows their centre, in 3:4. A vertical illustration comes through almost intact. A spread or a wide frieze loses its edges: split it into two or three images in a carousel rather than shrinking it until it is unreadable. A square image can keep its 1:1 format, which Instagram also accepts in the feed.
What the caption should say
The project title, the publisher or client, what you did (cover, interior illustrations, poster), the medium, then the credits. For example:
“The Winter Garden” — Cover and 24 interior illustrations for a picture book.

Add a hashtag for your speciality (children's books, editorial, publishing, posters): that is how art directors search.
Publishers, authors and collaborations
Tag the publisher, the author, the agency or the brand, and invite them to a collaborative post: it also appears on their profile, in front of readers already curious about the project. For a commission, wait for the publication date or the client's agreement before showing the images.
How often to post
Two to three posts a week are enough, as long as you keep it up. One project naturally gives three posts spread over a month: the carousel, a detail or a process step, then the printed object or a Reel. With a dozen projects on your website, you already have several months of posts.
Mistakes that cost followers
- Posting a whole book on the same day, then nothing for weeks.
- Shrinking a spread until it is unreadable instead of splitting it.
- A caption with no publisher or client: nobody can tell who you work for.
- A big watermark in the middle of the drawing.
What Foliocast does for an illustrator
- One carousel per project, cropped to 4:5 or kept square, with a focal point you set: the character stays in the centre.
- A caption that names the publisher or client, what you did and the medium, taken from the project page.
- A Reel that runs through the project's images, titled and set to music.
- Your portfolio read as it is: WordPress, Behance, Adobe Portfolio, Cargo, Squarespace, Wix and most hand-built sites.

What it does not do
- It does not draw or retouch: it crops your images, without touching the colours.
- It does not know publication dates or embargoes: you choose when each project goes out, and nothing goes out without your approval.
- Galleries without titles (ultra-book, Pixpa) arrive with their images but no project name: you name them at step 02.
- It does not reply to comments or messages: it posts, then shows you what worked.
Reels and posting times learned from your statistics need a paid plan, from Solo; carousels, captions and hashtags are in the free version. See pricing.
Let your portfolio post itself
Your projects are already presented in your portfolio: the images, the text, the publisher, the credits. Foliocast uses them to prepare carousels, captions and hashtags, crops the images to the right format and posts at the right time, even with your computer off. You approve once. The tutorial shows the setup in 10 minutes.
