When I load an image-set and click on "Calculate optimal size" Hugin sets the Canvas Size to 19,450 x 9,725. It appears my math is consistent with what Hugin tells me the "optimal" size is. But without exception when a pano is complete the X dimension is in the low 13,000 range.
When you create a project with the Assistant tab, Hugin downscales the canvas size from the 'optimal' size - The amount is configurable in Preferences -> Assistant -> Downscale final pano.
It does this because it speeds up stitching, and you lose hardly any information doing this with typical digital photos.
(Camera CCDs use a Bayer pattern, so for example an 8 megapixel camera only has 4 megapixels of green, and two megapixels of red and blue)
