The running time of Spider-Man: Brand New Day is 145 minutes.
A 145-minute runtime is equivalent to two hours and 25 minutes. The figure refers to the completed theatrical film and is separate from trailers, advertisements, and any cinema-specific presentation material.
The story covers several connected threads: Peter Parker's life after the memory-altering spell in No Way Home, his street-level work in New York, the return of familiar MCU figures, and the emergence of changing powers.
Runtime figures can vary slightly in informal listings if they are rounded or if a source includes additional material. The film's official encyclopedia-style listing gives the precise theatrical length as 145 minutes, making that the canonical answer for this question.
