Unit Size

The distribution of size of units (measured in lines of code).

Intro
  • Unit size measurements show the distribution of size of units of code (methods, functions...).
  • Units are classified in four categories based on their size (lines of code): 1-20 (small units), 20-50 (medium size units), 51-100 (long units), 101+ (very long units).
  • You should aim at keeping units small (< 20 lines). Long units may become "bloaters", code that have increased to such gargantuan proportions that they are hard to work with.

  • There are 23,233 units with 538,882 lines of code in units (42.7% of code).
    • 913 very long units (185,043 lines of code)
    • 1,421 long units (98,488 lines of code)
    • 3,961 medium size units (124,289 lines of code)
    • 4,656 small units (68,913 lines of code)
    • 12,282 very small units (62,149 lines of code)
