        }
        catch

You can use MoveWindow - to change window size and GetWindowRect - to get current position of window.

First of all add this namespaces:

 using System.Diagnostics;
 using System.Runtime.InteropServices;

Next - add P/Invoke code:

[DllImport("user32.dll", SetLastError = true)]
internal static extern bool MoveWindow(IntPtr hWnd, int X, int Y, int nWidth, int nHeight, bool bRepaint);

[DllImport("user32.dll", SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool GetWindowRect(IntPtr hWnd, ref Rect lpRect);
[StructLayout(LayoutKind.Sequential)]
private struct Rect
{
   public int Left;
   public int Top;
   public int Right;
   public int Bottom;
}

Finally after your Process.Start you can use this procedure, which changes chrome window size:

public void SetChromeSize(int width, int height)
{
   var procsChrome = Process.GetProcessesByName("chrome");   // there are always many chrome processes, so we have to find the process with a WindowHandle
   foreach (var chrome in procsChrome)
   {
      if (chrome.MainWindowHandle == IntPtr.Zero)    // the chrome process must have a window
         continue;

      var rct = new Rect();
      GetWindowRect(chrome.MainWindowHandle, ref rct);            // find and use current position of chrome window

      MoveWindow(chrome.MainWindowHandle, rct.Left, rct.Top, width, height, true);        //use MoveWindow to change size and save current position
      break;
   }
}
