From a theoretical standpoint, Light Novels and Manga are seriously two separate types of media, and evaluating The 2 might appear odd at the beginning.
Nonetheless - and I assume this is the underlying assumption for this concern - during the modern Japanese sector, it is fairly widespread that product existing in one of several two sorts becomes the basis for the opposite.
The commonest circumstance is the fact that one thing exists as a well-liked light-weight novel first, after which receives transformed right into a manga, not one other way around. Or, in the case of a very fashionable novel, the changeover may even be straight into an anime.
As for "what receives changed along the best way": Properly, not everything A great deal, to be sincere. Which means the adaptations can be a ton additional trustworthy than you might anticipate.

Largely due to the fact, not like "authentic" guides, light-weight novels (not less than 99% of those that turn out to be manga/anime) often get composed for a particular goal group with a particular "anime-ish" attitude to begin with... so once the change to manga/anime truly occurs, There's not much required when it comes to adaptational modifications.
Character Visuals:
Opposite to Anything you may perhaps Imagine, Light-weight Novels do have shots. Both of those on the quilt As well as in the form of numerous splash-webpage illustrations dotting Each and every volume. And these tend to be truly stunning and well-done much too, generally mainly because you will discover just a few of them (<10). So, unlike inside of a manga, the artists can shell out many time on them.
As for alterations, the level of on-character-visual-element may well get diminished (mostly for anime) for Price-cutting explanations. But commonly, the artists consider difficult to stick with the originals, not to alienate the by now-current followers.
Character count:
There is rarely any requirement to remove characters with the Solid. If something, it's extra probable that further characters get released so the manga/anime Edition can be padded out and designed for a longer time. Nevertheless, most often this transpires In any case the "novel material" obtained employed up (see also "plot").
Plot:
The basic plot buildings and crucial plot points commonly remain a similar. Even so, Take into account that mild novels are serialized, and like manga<->anime adaptations it may possibly come about that the manga/anime has "applied up" all the existing product prior to the novel is done. In that scenario, filler arcs get produced to acquire time. Only in the case of really prolific authors, current novel plot arcs get dumped when building the manga/anime. Slayers can be one these example.
Last but not least, another rather typical go is that the novel/anime/manga variations have slightly distinctive endings. At times to "get it done a lot better than the first time all around", but more typically simply to help keep the people enthusiastic about all forms of that franchise.
Environment:
Manga/Anime are comparably liberal artwork types, so likelihood is good that not Considerably receives modified. Having said that, fairly Obviously, whenever you desire to obtain a broader audience, there is usually a particular temptation to tune down the general tone a bit. Adhering to that Idea, manga versions Possess a slight inclination to generally be tamer compared to the novels, and anime versions might be notably tamer than the manga.
Narrative design:
Gentle Novel variations provide the reader far more the perfect time to procedure data, so they have an inclination to possess far more element As well as in-depth scene/setting descriptions. Also, they are usually additional dialogue-pushed than another kinds, so it's actually not uncommon that dialogue gets shortened and simplified for manga/anime versions. Eventually, sure scene transitions merely Will not get the job done well in visual form, so There's also some streamlining taking place while in the sequence of scenes, together with dropping some whose information then receives conveyed elsewhere.
