Recommended dimensions for visual assets such as images, autoplay videos, and overlay images are typically specified within an element’s Title Bar (e.g., Hero 1920 x 1080). These dimensions help ensure that the visual assets fit seamlessly within the design of the page, maintaining the intended layout and appearance. By default, the dimensions in the Title Bar refer to pixel size, meaning 1920 x 1080 refers to an asset that is 1920 pixels width and 1080 pixels height.

Using the specified dimensions ensures that your visual assets display clearly and correctly without being stretched, compressed, or cropped incorrectly. It's important to adhere to these recommendations for optimal performance, as assets with incorrect dimensions might affect loading times, layout consistency, or user experience. Additionally, using the right dimensions can improve how your assets look across different devices, ensuring they remain sharp and well-proportioned, particularly on high-resolution displays.
