As anyone that works with Microsoft products (especially older ones) knows, it can be extremely difficult to get one of their products to work well across different browsers.

In SSRS 2005’s Report Manager the reports appear to look scrunched because the size hasn’t been properly set on an iframe. Unfortunately, we have to fix part of the core’s CSS if we want the reports to properly render in the Report Manager.

We need to edit the following file:
C:Program FilesMicrosoft SQL ServerMSSQL.2Reporting ServicesReportManagerStylesReportingServices.css

Add the following code to the end of the file:

.DocMapAndReportFrame
{
min-height: 500px;
min-width: 500px;
}
