I found excellent answer,

http://prafull-blog.blogspot.ca/2012/06/how-to-calculate-record-size-of-hba
se.html

Quote:

"So to calculate the record size:
Fixed part needed by KeyValue format = Key Length + Value Length + Row
Length + CF Length + Timestamp + Key Value = ( 4 + 4 + 2 + 1 + 8 + 1) = 20
Bytes
Variable part needed by KeyValue format = Row + Column Family + Column
Qualifier + Value"


Thanks,

Fuad
