Rendering an Image with a Specific Size I want to render an image that is, for example, 170 px by 180 px. How can this be done in blender? I'm using the cycles render. Is the process any different for an animation?
You can specify the render size in the dimensions section on the render panel just as you do for any other image rendering. To get the full resolution of the final image, also make sure that the Percentage scale for render resolution slider is set to 100%.

This setting is also for animations, and behaves exactly the same way.
