In case you haven’t noticed, the most recent “in print” papers from JGR-Space Physics have a new look, especially the PDF layout. Check it out! I think it is a fantastic and much-needed improvement to the “printed” version of the journal.
As you can see, the text is now a single column and the left side of the page has an extra-wide margin of white space. JGR-Space is no longer a two-column format journal. I like it and others tell me that it works very well on tablets and other mobile devices.
A concern has been raised about this new PDF format, however. That extra-wide margin means that the text is no longer as wide as it used to be. The concern is that figures cannot be as wide as the old double-column width format option. Your figures, however, are not limited to the width of the text, but can extend across the full extent of the page. You can still have landscape figures, too, rotated 90˚ in the PDF. In fact, figure widths are no longer limited the way they used to be, because there is no need to make them exactly match single or double column width. Any figure size is acceptable now, and the text will simply wrap around it. If a figure is too big to fit on a printed page, then perhaps it is best to either break it up into multiple figures (you do not pay extra for color figures), each highlighting some aspect of the over-sized figure, or include it as an electronic supplement (which will be available via a hyperlink from the PDF).
That said, it is aesthetically pleasing to make figures that match the text width, or that are roughly half the width so the text can wrap smoothly around it. So, during production, Wiley staff will work with you on the exact layout and sizing of your figures. You have a say in these formatting issues; please feel empowered to voice your opinion about the presentation of your work.
