Rotativa ViewAsPDF CSS Sizing / Dimensions

Question

I am rendering an HTML View in ASP.Net MVC to PDF using Rotativa `ViewAsPdf` method. I am setting the ouput to be of A4 Size, Portrait and no margins, by setting: ``` new ViewAsPdf(MVCCfpFormatter.Members.Views.FlightPlansFullPagePrint, model) { // FileName = flightPlan.ListingItemDetailsModel.FlightDetails + ".pdf", PageSize = Size.A4, PageOrientation = Orientation.Portrait, PageMargins = new Margins(0, 0, 0, 0), PageWidth = 210, PageHeight = 297 }; ``` Then within the CSS, I am setting an element to have `210mm` width, which should spread the entire width of the page, yet in the output PDF, the `210mm` width is not representing the entire width of the PDF but less. By trial and error, the total width of the generated PDF seems to be around `246mm`. Any ideas why this could be happening?

Accepted Answer

If you are still having issues ive done more research on rotativa. You can use custom switches from wkhtmltopdf. Try and add

```
CustomSwitches = "--disable-smart-shrinking". 
```

That stops the program from auto resizing your things. From there you can adjust your html page correctly to get the size you want on the pdf.
