Textures in Unity are typically created at 2x the needed resolution in order to facilitate a balance between quality and performance. This approach allows developers to ensure that textures retain sufficient detail for different camera distances and various graphic settings. By designing at a higher resolution than what is ultimately displayed, it provides flexibility for downsampling, which can enhance visual fidelity on higher-end systems while still maintaining performance and memory efficiency.

Creating textures at this resolution prepares them for potential scenarios where they might be viewed in more detail or at closer proximity than anticipated. Additionally, 2x the needed resolution helps compensate for potential loss of quality due to mipmapping, which is a technique used to improve performance by selecting lower-resolution textures based on the distance of the camera from the object. This technique of authoring at a higher resolution ensures that even when textures are scaled down, they retain their sharpness and detail, leading to a more polished final result in-game.
