Britain’s graphic-novel market is growing, but the more consequential question may be what happens after young readers outgrow the children’s shelves. Emma Hayley, founder of SelfMadeHero, has argued that publishers need to stop treating comics as a temporary stop on the way to “real” reading and instead regard visual storytelling as a serious form for readers throughout their lives.
That is not simply a cultural argument. The available sales figures show meaningful momentum: adult graphic novels reached £52.8 million in the UK in 2025, up from £48.7 million in 2024. Children’s comic-strip fiction and graphic novels rose from £20.3 million to £25.9 million over the same period. Together, the market totalled £78.7 million in 2025, a year-on-year increase of 13.9% and roughly £46 million higher than in 2019.
Those numbers make the opportunity clear, but they do not guarantee a durable ecosystem. Hayley’s warning is that a generation accustomed to reading comics as books will eventually look for more sophisticated work in the same medium. If publishers, booksellers, reviewers and festivals do not make that work easy to discover—and do not build the specialist knowledge needed to make it well—the market could leave interested readers with far fewer routes forward than its children’s boom suggests.
Children’s comics are changing the reading pipeline
British children have been comic readers for a long time. The Beano, for example, approached two million weekly sales in 1950. What has shifted is the prominence of the graphic novel as a book format and the accompanying change in status. Children are now encountering sequential art not as disposable diversion but as a regular part of bookshop, library and classroom reading.
That distinction matters. A graphic novel is not defined merely by having pictures. It tells a story through sequential art: meaning is created across a sequence of images, panels, page turns, captions, dialogue and visual pacing. Readers actively connect the spaces between panels, interpreting time, action and emotion from what is shown and what is omitted. The result can be fast, funny and accessible, but it can also be structurally intricate, politically engaged and emotionally demanding.
For young people learning to read this way, comics literacy is not a lesser version of prose literacy. It is familiarity with a different storytelling grammar. Page composition can control the speed at which a reader absorbs an event; lettering can establish tone or emphasis; the relationship between narration and image can add irony, ambiguity or contrast. A silent panel can carry information that would take several prose paragraphs to explain, while a dense page can reward close rereading.
The practical implication is straightforward: readers who have grown up enjoying that grammar may not suddenly abandon it because their tastes become more mature. Some will move between prose, comics and other forms. Others will continue to seek comics specifically. A healthy adult and YA offering does not require every young graphic-novel reader to become an adult graphic-novel buyer. It requires the industry to be ready for those who do.
Strong sales do not automatically mean broad support
The current British market has genuine successes. Titles cited as major breakout examples include Heartstopper, Dog Man, Bunny vs Monkey, Persepolis, Fun Home and Blankets. Their visibility proves that comics can break through to large audiences across age groups and subject matter.
But breakout books can conceal a structural weakness: sales may be concentrated among a limited number of exceptionally familiar titles. That is different from a market in which readers can readily find a wide range of new creators, genres and formats. One bestseller can bring people into a category; it cannot by itself ensure that those people encounter their next five books.
Manga is an especially important part of the picture. It accounts for almost half of adult graphic-novel sales in the UK. That share demonstrates powerful demand for comics reading, yet it also makes the shape of the market more complicated. Broad category growth can coexist with a narrow domestic publishing base if much of the activity depends on particular franchises, formats or imported work. Hayley’s argument is not that manga or successful individual books are a problem. Rather, a confident comics culture should be able to build on their popularity by supporting a broad, visible field of work.
Visibility is an unglamorous but crucial word here. It includes how books are shelved and recommended, whether reviewers take comics seriously, whether festival programmes make room for cartoonists, and whether readers encounter graphic novels outside a handful of blockbuster moments. It also includes the language used around the form. Calling comics a bridge to “proper” books sends a clear message that readers are expected to leave once they have crossed it.
What “being more French” actually means
Hayley’s comparison is with France’s bande dessinée tradition, often shortened to BD. The point is not to reproduce French titles or publishing habits wholesale. It is to recognise the cultural premise behind the comparison: comics can be an ordinary, respected part of adult reading life, rather than a curiosity that must continually argue for legitimacy.
The scale cited for France illustrates the gap in confidence and market maturity. The bande dessinée market sold 68 million copies there in 2024 and generated €837 million, described as around £700 million. Numbers from different countries and currencies are not a neat like-for-like measure, and they do not establish a single policy solution. Still, they show what can happen when comics occupy a larger place in mainstream bookselling and cultural conversation.
For Britain, the useful lesson is not that every comic must be marketed as literary prestige work. Comics can be satirical, romantic, experimental, political, profound, escapist or simply entertaining. The larger issue is range. An adult reader should not have to defend choosing a comic any more than they would have to defend choosing a novel, memoir, history or poetry collection.
That wider acceptance would also help books find the audiences for which they are already suited. Persepolis, Fun Home and Blankets appearing among recognised titles is a reminder that the medium has room for memoir and personal storytelling as well as comedy, adventure and serialised genre fiction. The next step is not to insist that all comics resemble those books. It is to make the marketplace capable of presenting diverse work on its own terms.
Publishing comics requires specialist craft
One of Hayley’s most useful points is that graphic-novel publishing is specialised work. Comics do not become successful merely when prose manuscripts are paired with illustrations. Editorial development has to account for layout, lettering, pacing and the constant relationship between text and image.
Layout concerns how panels are arranged on a page and how the eye travels through them. It can establish clarity or purposeful disorientation. Lettering is the presentation of dialogue, captions and sound effects; its legibility, placement and style affect how a reader hears a character and understands the order of a scene. Pacing is the management of time and attention. A single splash image might slow down a pivotal revelation, whereas a page packed with small panels can create compression, urgency or comedy.
Then there is the interplay of words and pictures. Sometimes text tells the reader what the picture cannot show. Sometimes the image contradicts the narration. Sometimes neither is complete without the other. Editing this work demands an understanding of what each element contributes and when removing words, redrawing an image or changing a page turn can materially improve the story.
That is why calls for serious investment extend beyond acquiring more projects. They include education and training for creators and editorial teams, plus routes for talent to develop work before it reaches a finished-book stage. Hayley points to the First Graphic Novel Award, the UK prize for works in progress, as evidence that there is substantial British talent awaiting publication opportunities. A works-in-progress prize matters because comics are labour-intensive and iterative: creators need time, feedback and informed support while the book is taking shape.
Encouraging recognition, but no reason for complacency
There have been signs of increased recognition. The British Book Awards introduced a Graphic Novel category for the first time, with Jamie Smart’s Bunny vs Monkey: Intergalactic Monkey Business! taking the award. The Hay Festival also staged a dedicated Comics & Graphic Novels Day, while the Comics Cultural Impact Collective has been making the cultural and economic case for the form.
These are meaningful developments, particularly because recognition creates occasions for readers and industry professionals to notice books that might otherwise be missed. Yet a category, a festival day or a viral hit is not the same thing as long-term infrastructure. The sustained work lies in commissioning, editing, selling, reviewing, displaying and discussing comics all year, across children’s, YA and adult publishing.
There is a wider publishing context, too. Different ways of reading and listening are increasingly treated as part of the same audience conversation; debates around expanding audio offerings, including reported interest in audiobooks and AI narration, underline how format can shape access and discovery. Graphic novels deserve the same practical attention to format—not as an unusual product category, but as a medium with its own strengths, audience expectations and production needs.
The challenge is continuity
The central question is not whether every child who enjoys a graphic novel will eventually read adult comics. No form retains every reader, and no one reading path needs to be compulsory. The test is whether the industry can offer a credible next step to the many readers who want one.
That means YA and adult lists with genuine breadth. It means retailers and librarians having confidence in recommending more than the titles readers already know. It means reviewers treating visual storytelling as criticism-worthy rather than as a novelty. It means festivals continuing to programme comics alongside other literature, and publishers investing in people who understand the medium’s craft.
The sales growth suggests that readers are already doing their part: buying, borrowing, rereading and recommending comics. Britain’s task is to decide whether it wants that enthusiasm to remain dependent on a few household names, or to support a lasting comics culture that gives readers more to discover as they grow.
