title: How to determine a good initial size for SQL Transaction LOG file?
body: <p>We run SQL Server 2008 R2. The database sizes vary from 20-500 gb, and are all in full recovery mode.</p>
  
  <p>I find it hard to determine a good initial size for the transaction log files, to prevent autogrowth's. It depends on multipele factors, but can anyone give some rule of thumb on a good value for the initial size of the log? Can I see how fast a log is growing in the last xx time or something?</p>
  
  <p>Any advice on this subject is very welcome.. thanks!</p>
