If you want your layout pack to contain scenes with different aspect ratios — for example, a [scene](/getting-started/scenes) with a square layout for social media clips — you'll need to create additional [compositions](/working-in-projects/overview) with different [aspect ratios](/working-in-projects/aspect-ratio) in the same layout pack project. To create additional composition: 1. Click the down arrow icon next to your composition's name. 2. Select **New composition** at the bottom.\\ New Comp.png To adjust the composition's aspect ratio: 1. Select the rectangle in the top left of the [scene editor](/visuals/scene-editor-overview). 2. Choose one of the aspect ratio option from the list.\\ Aspect Ratio.png ## Related topics - [Aspect ratio and video settings](/working-in-projects/aspect-ratio.md) - [Use templates to speed up your Underlord workflow](/templates-and-presets/underlord-templates.md) - [Share a custom layout pack](/templates-and-presets/layouts-sharing.md) - [Layout packs overview](/templates-and-presets/overview.md) - [Create a custom avatar](/generative-media/custom-avatars.md)
