SizeToReportContent works with Height and Width

Hi 

I have this configuration in aspnet....

<rsweb:ReportViewer runat="server" Font-Names="Verdana" Font-Size="8pt" Height="482px" SizeToReportContent="True" WaitMessageFont-Names="Verdana" WaitMessageFont-Size="14pt" Width="1213px">
</rsweb:ReportViewer>

Is it correct: SizeToReportContent="True"  and write: Width="1213px" and  Height="482px"
