<p>If the blocksize is increase to 2MB will that mean twice as many transactions? Basically how much of the space is used on the standard variables found in the block?</p>

[A block begins with a header of 80 bytes, and everything else is used for transactions.](https://en.bitcoin.it/wiki/Block) So if you increase the maximum block size from 1000000 to 2000000 bytes, the space available for transactions grows from 999920 to 1999920 bytes, which is just slightly more than double.
