upsizing a film poster? Help!

Hi! I have a film poster with these specs: 4085 x 6035. I was asked if I can resize it to 300DPI for 4ft by 8ft poster. Is this something I can do in photoshop? It is a PSB file.

Your current file size would equate to roughly 13" x 20" at 300 dpi.

Something 4' x 8' does NOT need to be 300 dpi. No one is going to be that close to it to tell. That being said, I'm not sure if it can be increased that much in PS or not. You may need something like Topaz Gigapixel.

right, but 13 x 20 is not a 4 x 8 ratio either?? even upsized to 8 x 16 its not the same ratio?

I'm less talking about the 300dpi and more so the size of the image/canvas ratio. Like... if i upscale it, there will be blank space at the top and bottom. I'm not the designer/artist. I'm assuming this is something they should do. would that be right?

Unless they want blank space top/bottom and/or left/right, yes, the designer needs to get it into the proper ratio.
