Estimating partition size

I am going through book 'Definitive Cassandra'. It gives a generic approach to estimate partition size. I have few questions over it. In its approach, book says that in our calculations we need to use number of columns as (total number of columns - columns in primary key). Why should this be so? Partition key is same for all rows, so that is fine, but other members in primary key may be different for the rows in partition?

I think you misunderstood the book. If you read it again, it is referring to "the number of values per row". Not the partition size. Cheers!
