Recommended prompt sizes

Creative asset specifications for platform prompts. Includes recommended image sizes, aspect ratios, and supported file types for Inline and Overlay prompt styles across web, mobile, and TV SDKs.

Overview

Recommended prompt sizes is a technical specification guide that outlines the supported parameters for creative assets. It details which prompt styles (e.g., Horizontal, Tile, Popup) and prompt types (Inline, Overlay) are available on specific platforms (Web, native iOS, Android TV, ROKU, etc.), and provides the recommended width and height (in pixels) and supported image file types (png, jpg, gif) required for production.

Key benefits

  • Accuracy in production: Provides the exact pixel dimensions for every supported prompt, eliminating guesswork and preventing the creation of assets that are improperly sized or scaled.
  • Streamlined creative workflow: Confirms the required aspect ratios and accepted file formats (png, jpg, gif) upfront, allowing teams to set up design templates correctly from the start.
