I've attached a version of your filter which works for double wide, for instance 1200x600 (File->New). I've changed the front end (square line design) to Default anchors, the back end to Image Bounds anchors. I've added a Bomber for the square line design, which then repeats the square line design for wide images.

Note that this does NOT work for tall images. You will need to redesign your filter so that all the design elements (including Tiles) are fed to a Bomber, using Default anchors in all cases. The Bomber will deal with differences between height and width.

Hope this makes sense. You might want to clean up your filter a bit, it was hard to follow with nodes overlapping and often not left to right.

UPDATE: this new version still does not fix all of the design elements, but the information I've given you should allow you to fix the various issues still existing with my tweaking of your filter.

Rachel,I wonder if your double-wide technique can be applied in polar-to-rectangular remapping (Spherize)?

I'll see if I have a snip you can try it on (or you could use Planetary Noise)...
