+ 0.15 = Hole Size. However, IPC-2222 has a table that is inclusive and calculates the hole size based on Density Levels. See image below. Once the Hole Size is established, the main point for pad size calculation in the IPC-2221 standard is the minimum annular ring of the plated through-hole pad stack after fabrication tolerances are
