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 364 units with 8,615 lines of code in units (35.5% of code).
    • 16 very long units (3,982 lines of code)
    • 24 long units (1,693 lines of code)
    • 53 medium size units (1,677 lines of code)
    • 44 small units (654 lines of code)
    • 227 very small units (609 lines of code)
