To use the guidelines for PCB footprint design, you should look for

Contour Courtyards: Moves away from strictly rectangular courtyards to contour-based outlines that allow for tighter component density while maintaining assembly clearances. ipc-7351c pdf

: Determine if your project requires Class 1 (General), Class 2 (Dedicated Service), or Class 3 (High Reliability/Aerospace) standards. Consult the Land Pattern Calculator To use the guidelines for PCB footprint design,

What is IPC-7351C?

IPC-7351C, titled "Generic Requirements for Surface Mount Design and Land Pattern Standard," is a global standard published by the Association Connecting Electronics Industries (IPC). It provides specific mathematical formulas, dimensional tolerances, and naming conventions for creating land patterns (often called footprints or pads) for Surface Mount Devices (SMDs).

Without the PDF standard, you would have to guess the manufacturer's intent.
