Depth of field depends on seven factors, not just the four that most people think of. In addition to focal length, f/stop, and distance, DoF depends on film size, print size, viewing distance, and visual acuity.
This is the only calculator that I know of that applies all seven: http://eosdoc.com/jlcalc/ Explore it and vary all 7 variables.
You can't just go with a given size for the CoC.
Then go with the results of the DoF calculator and/or the DoF markings on the camera lens if it has any.
