There is a default minimum amount of 1024 bytes and then the rest of the content length and properties are added to that. I believe this is done to account for the encoding of the protocol used and for performance reasons so it's not all that accurate and is more of an estimation.
You can override the minimum message size setting as part of the Policy. Take a look at http://activemq.apache.org/per-destination-policies.html and look at the minimumMessageSize property.
