Difference between Teaser and Trailer

Teaser and trailer are two different ways of advertising a film. Although both serve the same purpose, they are different from each other. Let us see how a teaser differs from a trailer!


A teaser is a way of advertising a film by releasing a teaser months before the release of a film. It contains little content from the film and is released to entice or tease the audience and increase the hype of the film prior to the release of its trailer. The length of a trailer is usually around 20-30 seconds. It is generally created during the shooting of the film and released before the completing the shooting and editing of the film.

A teaser arouses curiosity in the audience as it lasts less than a minute and does not provide details of the film. Teasers are generally created for big budget films that have a greater target audience. They are also used for the sequel of a hit film in order to create hype or buzz for the film that already has a large audience base with an existing knowledge. So, teasers are just a clue or hint at what is going to happen and do not confirm anything.


A trailer is a way of advertising a film that is going to be released in the near future or after few months. It is longer than a teaser and provides a brief idea about the plotline of the film. A trailer comprises a series of sequences from the film. It generally follows a non-linear structure so that audience is not able to figure out the story of the film and would like to watch the full movie.

Trailers usually contain the most exciting parts of the film in order to encourage the audience to watch the full film. The length of a trailer can be up to 2 minutes and 30 seconds.
