title: Calculate physical size for a single row in a table with sql server
body: <p>I am creating an application to provide limited space in database as gmail account. I want to charge from customer as per their data storage space. I have googled but not found proper solution.</p>
  
  <p>I want to calculate the physical size (Hard disk space) for a single row of a particular ID from different tables in a database. I am using sql server.</p>
  
  <p>Take an example to understand this:</p>
  
  <p>We all are use gmail and have a limited space 5GB for our mail storage space on server. When we exceed the limit of storage space then we have to remove some data from our account to get free space(as also use in hard disk).</p>
  
  <p>There may some different functionality for gmail as per my thought but I need this.</p>
