The 32-bit version of SP1 is around 755MB and the 64-bit edition comes in at around 1GB.
Says Microsoft:
Starting today, Windows 7 Service Pack 1 will be available to everyone via the Microsoft Download Center and [will] start rolling out via Windows Update.
If you prefer to have a disc, you can get one sent to you for $6 from Microsoft, including shipping.
The public beta of the SP was released in July 2010, and Microsoft launched the release candidate in October. The SP1 brings no new features, but is instead a collection of security patches and nonsecurity fixes already available through Windows Update.
