Tuning Matter ==> Parameter PCT_USED in a Table

Dear Listers,

I've download a presentation talking about Calculating PCT_USED . the formula is quite simple :
PCT_USED + PCT_FREE < 100
PCT_USED = PCT_FREE + 1 row size

but I have no idea to calculate the size of 1 row in a table .

is there anyone who knows to calculate it ? or any alternative formula to calculate PCT_USED ?

Thanks a lot in advance : )
