Enter the uncompressed size and the compressed size into the Calculator. The calculator will evaluate the Text Compression Ratio. 

Text Compression Ratio Formula



  • TCR is the Text Compression Ratio ()
  • US is the uncompressed size
  • CS is the compressed size

To calculate the Text Compression Ratio, divide the uncompressed text size by the compressed text size.

How to Calculate Text Compression Ratio?

The following steps outline how to calculate the Text Compression Ratio.

  1. First, determine the uncompressed size. 
  2. Next, determine the compressed size. 
  3. Next, gather the formula from above = TCR = US / CS.
  4. Finally, calculate the Text Compression Ratio.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

uncompressed size = 5

compressed size = 6
