Try using the ViewBox

<Viewbox>
    <RichTextBox />
</Viewbox>

Set the HorizontalAlignment and VerticalAlignment to something other than Stretch (which is the default). This will make the TextBox shrink to fit its contents. If you then stick it inside a StackPanel with Orientation of Horizontal it will not scroll vertically but be clipped by its containing panel, which I think is what you are after. If you want you containing panel to resize itself to the text, then you need to configure the panel accordingly

        Bitmap objBmpImage = new Bitmap(1, 1);

        int intWidth = 0;
        int intHeight = 0;

        // Create the Font object for the image text drawing.
        Font objFont = new Font("Arial", 20, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Pixel);

        // Create a graphics object to measure the text's width and height.
        Graphics objGraphics = Graphics.FromImage(objBmpImage);

        // This is where the bitmap size is determined.
        intWidth = (int)objGraphics.MeasureString(sImageText, objFont).Width;
        intHeight = (int)objGraphics.MeasureString(sImageText, objFont).Height;

You already have string to set textbox. Firstly, you can calculate like above to measure proper size of richtextbox. you can just set intWidth and intHeight at textbox. I think that makes you helpful.
