How the guides differ from tools
Guides answer a question in prose: what the colon means, how to simplify a width and height, how crop differs from pad, and how padding changes a frame without cutting it. Tools are the forms that apply those steps to a number you type, usually the missing width or height of a ratio.
Each guide links back to the calculator that uses the same rule, so the worked example and the live result stay on one formula.
