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.

    • 17 very long units (2,234 lines of code)
    • 16 long units (1,118 lines of code)
    • 116 medium size units (3,717 lines of code)
    • 132 small units (2,003 lines of code)
    • 266 very small units (1,679 lines of code)
