Several of Charles Dickens' novels appeared in installments. As readers waited for each new issue, suspense and chapter structure became closely connected to the publishing schedule.

His work portrays urban poverty, children's circumstances, and social institutions. Serialization also allowed continuing interaction with readers before a novel was fully written.

Literary style

Dickens's approach to the novel is influenced by various things, including the picaresque novel tradition, melodrama and the novel of sensibility. According to Ackroyd, other than these, perhaps the most important literary influence on him was derived from the fables of The Arabian Nights. Satire and irony are central to the picaresque novel. Comedy is also an aspect of the British picaresque novel tradition of Laurence Sterne, Henry Fielding and Tobias Smollett. Fielding's Tom Jones was a major influence on the 19th-century novelist including Dickens, who read it in his youth and named a son Henry Fielding Dickens after him. Influenced by Gothic fiction—a literary genre that began with The Castle of Otranto (1764) by Horace Walpole—Dickens incorporated Gothic imagery, settings and plot devices in his works.

Victorian gothic moved from castles and abbeys into contemporary urban environments: in particular London, such as Dickens's Oliver Twist and Bleak House. The jilted bride Miss Havisham from Great Expectations is one of Dickens's best-known gothic creations; living in a ruined mansion, her bridal gown effectively doubles as her funeral shroud.

The author worked closely with his illustrators, supplying them with a summary of the work at the outset and thus ensuring that his characters and settings were exactly how he envisioned them. He briefed the illustrator on plans for each month's instalment so that work could begin before he wrote them. Marcus Stone, illustrator of Our Mutual Friend, recalled that the author was always "ready to describe down to the minutest details the personal characteristics, and... life-history of the creations of his fancy". Dickens employs Cockney English in many of his works, denoting working-class Londoners. Cockney grammar appears in terms such as ain't, and consonants in words are frequently omitted, as in 'ere (here) and wot (what). An example of this usage is in Oliver Twist. The Artful Dodger uses cockney slang which is juxtaposed with Oliver's 'proper' English, when the Dodger repeats Oliver saying "seven" with "sivin".

Episodic writing

A pioneer of the serial publication of narrative fiction, Dickens wrote most of his major novels in monthly or weekly instalments in journals such as Master Humphrey's Clock and Household Words, later reprinted in book form. These instalments made the stories affordable and accessible, with the audience more evenly distributed across income levels than before. His instalment format inspired a narrative that he would explore and develop throughout his career, and the regular cliffhangers made each new episode widely anticipated. When The Old Curiosity Shop was being serialised, American fans waited at the docks in New York harbour, shouting out to the crew of an incoming British ship, "Is little Nell dead?" Dickens was able to incorporate this episodic writing style but still end up with a coherent novel at the end.

He wrote, "The thing has to be planned for presentation in these fragments, and yet for afterwards fusing together as an uninterrupted whole."

Another important impact of Dickens's episodic writing style resulted from his exposure to the opinions of his readers and friends. His friend Forster had a significant hand in reviewing his drafts, an influence that went beyond matters of punctuation; he toned down melodramatic and sensationalist exaggerations, cut long passages (such as the episode of Quilp's drowning in The Old Curiosity Shop), and made suggestions about plot and character. It was he who suggested that Charley Bates should be redeemed in Oliver Twist. Dickens had not thought of killing Little Nell and it was Forster who advised him to entertain this possibility as necessary to his conception of the heroine.

When in 1863 the Jewish English reader Eliza Davis wrote to rebuke him for having "encouraged a vile prejudice against the despised Hebrew" with the character of Fagin in Oliver Twist, Dickens halted the second printing of the novel and made some changes to the original 1837 text. He also created a group of sympathetic Jewish characters in his next novel, Our Mutual Friend, published 1864–1865.
