RLE works best on data with long runs of repeated values (e.g. simple graphics, faxes) — highly varied data can even expand in size.

Formula and working

Compressed size = number of runs × (value bits + count bits); Ratio = original size ÷ compressed size

  1. 1

    Collect the inputs

    Total symbols/pixels in the data = 100,000; Number of runs (distinct consecutive groups) = 5,000; Bits per symbol/pixel value = 8; Bits used to store each run count = 8

  2. 2

    Apply the formula

    Compressed size = number of runs × (value bits + count bits); Ratio = original size ÷ compressed size

  3. 3

    Result

    Compression ratio = 10
