Twitch creators will soon be able to stream in horizontal and vertical formats simultaneously

Twitch just announced Dual Format streaming at TwitchCon Europe, and it's exactly what it sounds like. Creators can now stream in both horizontal and vertical formats simultaneously, so the same broadcast works whether someone's watching on desktop or scrolling on their phone.

This matters because vertical video has taken over mobile consumption, but most streaming setups are built for horizontal. Until now, creators had to pick one or risk losing viewers who prefer the other format.

The feature addresses a real friction point for anyone building an audience across platforms. TikTok and Instagram trained people to expect vertical video on mobile, but desktop viewers still want the traditional widescreen experience.

Twitch announced this alongside other updates at TwitchCon Europe, though the company hasn't shared a specific rollout timeline yet. For creators using AI tools to clip, repurpose, or analyze their streams, this could mean rethinking workflows to handle two simultaneous formats.

The move also signals where live streaming is headed. Multi-format broadcasting used to require separate streams or complex technical setups. Now it's becoming a platform feature, lowering the barrier for creators who want to maximize reach without doubling their workload.
