Best Stream Packages for Twitch Dual Format Streaming

Twitch Dual Format is changing the way streamers plan their layouts.

With this feature, creators can broadcast horizontal and vertical versions of the same stream at the same time, making it easier to deliver a polished experience for both desktop viewers and mobile audiences.

But a good Dual Format setup is not just a cropped 16:9 overlay.

Vertical streams need layouts that stay readable on phone screens, with enough space for gameplay, webcam, alerts, chat, labels, and widgets. That is why stream packages with vertical overlay assets are becoming more useful for creators who want a cleaner mobile-friendly stream.

On StreamSpell, you can find stream packages that support vertical layouts by using the store filter:

Features > Vertical Output Overlays

This helps you discover overlays made for Dual Format streaming, dual-output setups, mobile content, and multistreaming workflows.

Some great options include the Marathon Stream Overlays and Widgets, a futuristic sci-fi HUD package with vertical and horizontal layouts, widgets, reactive overlays, Stream Deck icons, and OBS profile support.

Another strong choice is the Lunar Silver Stream Package, a bold blue animated overlay pack with vertical scene versions, stream alerts, webcam overlay, stinger transition, modular elements, and Dual-Output compatibility for Streamlabs.

For streamers preparing for Twitch Dual Format, choosing a package that already includes vertical assets can save time and make both versions of the stream feel more balanced, readable, and professional.
