How many seasons does Peaky Blinders have?

How to get close to this number

British drama seasons are short — typically six episodes — and a successful one runs several of them across a decade. Six seasons over nine years is the shape of a British prestige drama, and the total episode count is closer to an American show's two seasons than to its six.

That season-length difference is the recurring trap in any television question comparing countries. A British season and an American network season differ by a factor of three or four in episodes, so counting seasons compares production decisions rather than amounts of television. Always convert to episodes before comparing across systems.

The film continuation in the explanation is increasingly common: a series that ends on television and continues as a feature. Streaming economics have made the boundary between series and film porous, and a question about how many seasons a story has is no longer the same as a question about how much of the story exists.
