# How to Write a Vertical Drama Script: The Rules of a $2.98B Mobile Format

_General · published 2026-05-04_

Vertical drama — 60–120-second episodic content built for mobile — is not compressed television. It operates on its own structural logic, and a new guide from Filmustage breaks down exactly what that means for writers. The format's scale is hard to ignore: short drama apps generated $2.98 billion in in-app purchases in 2025, a 115% year-over-year jump according to Sensor Tower's State of Mobile 2026 report. Platforms like ReelShort, DramaBox, and MyDrama drove that growth by locking in a specific cadence that works in 90 seconds and nowhere else.

The guide outlines the core craft requirements: conflict must be structural to the premise rather than manufactured per scene, every episode must end on an unresolved cliffhanger (described as "the product, not optional"), dialogue should function as action, and writers should plan 60–100-episode arcs from the outset. Visually, the format lives in close-ups and emotional micro-expressions rather than locations or blocking. For screenwriters and producers looking to enter the vertical drama market, the piece offers a practical framework distinct from either TV or short-film conventions.
