To size a background image for your Blogger header; the image width needs to be the width of your blog (check in Template -> Customise -> Adjust Widths), and the image height needs to be 200px.
Go to Layout, and edit the header widget (the one with the title text on it). This will allow you to upload your image.
Thanks although in the end mine was not quite this size but the information you provided helped me to work it all out - as opposed to the numerous other places I read.
