Need help resizing Panorama for print

Hello I have a big panorama that I want to print. Currently the image dimensions in photoshop read 18.26 x 100 inches. I don't want this image to be cropped at all so I think I am going to need to add white space around the outside, and maybe a black border line. Can anyone tell me how to go about doing this? Also I would like this to actually only be 48" wide, would resizing the pano also require me to reduce the height?

Also is there a panorama print company that will accept a .tiff file? Thanks !

Your panorama is currently 100 inches wide by 18.26 inches tall - this is arbitrary because your panorama is really X pixels wide by Y pixels tall at some specified pixels per inch value (PPI). This value is based on how you would like to print the image.

Regardless, the aspect ratio of your image is: 100/18.26 or ~5.5 to 1. You can change this aspect ratio by adding whitespace or cropping if you want to, but if you do not, then changing the width to 48 inches will change the height accordingly:

100/48 = 0.48 - that is you changed the length to approximately 50% of the original - the height will change the same amount, or 18.26/2 = ~ 9 inches tall.

This is the way single row pano images work. They are usually very long compared to their height, or vice versa.

Considering the print size, you probably want to select a reasonable print width at the recommended PPI from the print lab. Or, use a standard PPI value for an inkjet printer of something like 300 - 360 PPI.

Awesome, thanks for sharing the math. Its pretty simple now that I see what goes into the process. I have the image setup for 300dpi already, will that translate over to the printer?

Yes - the PPI value (in your case 300) translates how pixels (which do not have a physical dimension) translate into real-world length and width. So, if your image is, for instance, 3000 pixels wide and you specify to print at 300 pixels per inch, then the physical size of the print itself will be:

3000 pixels / 300 pixels per inch = 10 inches.

Often, the PPI value that is specified for a particular print is determined by the printer and the anticipated viewing distance of the piece. For example, you don't need to print a billboard at 300 PPI - that would require a LOT of pixels and it would be excessive considering it would never be viewed up close.
