How do I know how much I have selected in GB

Question

When I try to sync I get an error telling me there's not enough room on the iPod. How do I know how many GB I have selected in iTunes before I hit sync? Is just a guessing game, or is there a way to find this out?
Thanks.

If your library is larger than the capacity of the iPod the use the update option 'Sync Music - Selected playlists'. When you open the playlist it will tell you at the bottom of the main window how much is in the playlist in terms of song, hours and GBs.
Open iTunes and create a playlist to update your iPod from, call it -My iPod for example (the dash will position it at the top of the playlists in Sources). Drag whatever content you want to have into the playlist. Now connect your iPod and when it appears in the Source list click on the iPod icon to bring up the preference tabs in the main pane. Go to the Music tab and choose Sync Music and the Selected playlists radio button. Choose the playlist you just made from the selection and click Apply. You can also sync from any existing playlists by choosing the same setting, you just need to make sure that the size of the playlists don't exceed the capacity of your iPod by looking at the information showing in the window for each one:

Syncing Music to iPod
Syncing selected playlists is just like syncing your whole library only on a smaller scale and more "selectively". When your iPod is is set to sync selected playlists it automatically picks up any changes you made to that playlist in iTunes since you last connected. Anything you added to the playlist will be added to the iPod, anything you deleted from it will be deleted from the iPod. In other words the iTunes playlist and the iPod are kept "in sync".
