1. Cartoon illustration style

Cartoon illustrations are a firm favourite in children’s books thanks to its bold lines, exaggerated expressions, and irresistible personality. This playful and expressive style is often used in story book illustration for younger readers, particularly in picture books, early readers, and humorous chapter books.

Out of the many different illustration styles, cartoon art is ideal for bringing characters to life with energy and emotion, making it one of the most recognisable types of illustration styles across publishing. It’s perfect for stories packed with fun, mischief, and memorable moments, and remains a go to choice when clarity, charm and instant appeal are key.

2. Sketch illustration style

Sketch illustration is all about raw energy. Often characterised by loose linework, visible pencil strokes, and a hand drawn feel, this style offers a more organic, spontaneous look that works beautifully in both fiction and non-fiction children’s book illustrations.

You’ll often find this approach in book illustrations that leans into diary formats, middle-grade fiction, or books aiming for an intimate, authentic tone. Among the many different illustration styles, sketch-based artwork adds charm, personality, and a sense of immediacy, proving that sometimes, a few well-placed lines can say a lot!

3. Digital illustration style

Digital illustration is one of the most versatile types of illustration styles used in children’s books today. Created using software like Procreate or Photoshop, this approach allows for rich textures, vibrant colours, and precise detail, all while maintaining a polished, professional finish.

Digital artwork can mimic anything from traditional painting to crisp vector graphics, making it ideal for a wide range of story book illustration, from bold picture books to highly detailed non-fiction titles. As one of the most popular styles of illustration, it offers flexibility and consistency across formats, perfect for publishers seeking visual impact with technical reliability.

4. Water colour illustration style

Watercolour illustration brings a soft, organic charm to children’s book illustrations, making it a favourite for gentle stories, nature led themes, and nostalgic narratives. Known for its fluid brushwork, delicate colour transitions, and natural textures, this style often features in picture books, fairy tales, and heartfelt stories.

Whether used in whimsical animal tales or dreamy bedtime stories, watercolour adds depth and warmth. Among the different illustration styles, this style stands out for its ability to evoke feeling and atmosphere, proving that sometimes the subtlest techniques can make the strongest impression.

5. Black and white illustration style

Black and white illustration strips things back to basics. This style of illustration relies on contrast, linework and texture to create striking, expressive visuals. It’s often used in chapter books, graphic novels, and more mature story book illustration, where the focus is on atmosphere, pacing and storytelling.

Among the many types of illustration styles, black and white stands out for its timeless quality and versatility. Whether it’s sketchy and loose or highly detailed and precise, this style proves that limited palettes can still leave a lasting impression in children’s book illustrations.

6. Fantasy illustration style

Fantasy illustrations bring imagined worlds to life through rich detail, dramatic composition, and often magical or mythical themes. This style of illustration is a natural fit for story book illustration and is especially popular in middle-grade and YA fiction. You’ll often see dragons, enchanted forests, talking animals, and heroic characters depicted in this visually immersive style.

Among the many different illustration styles, fantasy sits at the more elaborate and expressive end of the spectrum, with artists blending traditional and digital techniques to build atmospheric, otherworldly scenes.

As one of the more traditional types of illustration styles, pencil art allows for emotional nuance and atmospheric depth, making it ideal for quieter, character driven children’s book illustrations. Among the different illustration styles, pencil work stands out for its ability to feel both intimate and universally appealing, perfect for bedtime stories, gentle tales, and nostalgic narratives.
