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.

Unit Size Overall
  • There are 9,009 units with 128,935 lines of code in units (57.6% of code).
    • 108 very long units (20,638 lines of code)
    • 335 long units (22,925 lines of code)
    • 1,074 medium size units (33,455 lines of code)
    • 1,597 small units (23,575 lines of code)
    • 5,895 very small units (28,342 lines of code)
