There is such a table in "The Complete Book of Aquarium Plants" by Allgayer
and Teton. It shows surface area in cm^2 needed based on KH and tank volume
in liters. 

For a typical value of 5 dKH, surface areas are as follows:

Volume:  1,000   800   600   400   200   100 
Area:      180   140    80    50    30     *

For a value of 3 dKH, 

Volume:  1,000   800   600   400   200   100 
Area:      140    90    40    40     *     *

* CO2 produced by fish is sufficient under normal circumstances
