User CP Form Width 
$stylevar[formwidth_usercp]

The user control panel form width StyleVar does exactly the same job as the form width StyleVar $stylevar[formwidth], except that it allows the width of the navigation panel in the User Control Panel to be taken into account.

The red arrow shows the width controlled by $stylevar[formwidth_usercp].

For a discussion of the values this StyleVar will accept, see the page relating to the Form Width StyleVar $stylevar[formwidth].
