LDF deafult size coming as too small

Hi experts

  Just i played in SQL Server database, I created database without .ldf like this.

create database Data3
on 
(
 Name='Data3',
 Filename='F:\Test\Data2\Data3.mdf'
)

but .ldf created automatically but size is just 576KB, but normally default size of ldf is 1024KB, what is the difference ?

Can you please guide me,

Thanks - SelvaKumarSubramaniam.Please MARK AS ANSWER, if my answer is useful to U.
