You can get sorta-close with a steel rule, but that is no way to accurately measure the INSIDE DIAMETER of a brake drum. This tool BELOW by "Gearwrench" is one of the less-costly tools for measuring drums. I just gave-away an older one that has a dial on it that accurately measures in THOUSANDTHS of an inch (SECOND pic BELOW).
For instance, the LIMIT on OVERSIZE for old Ford drums is 12.060" (max) on a stock drum which is 12.000" to start with. In other words, ONLY 1/16" (approx) difference to be measuring wityh a ruler. DD
