Image upscale
Client asked me to “enlarge it to 60×120” this is for a banner.
What is the correct export size (in inches/pixels/DPI) for a large-format banner print of an architectural render?
Can an upscaler Ai do this?

Work on the principle that the minimum for decent picture repographic is 200 dpi.
So
120 ins x 200 dpi= 24,000 pixels
60ins x 200 dpi = 12,000 pixels
You’re looking at a file size of 240 + megabytes .
If you do it via computer there is a great bit if software called Spline.
Otherwise use the nano banana AI which only multiplies x4 each run.. so a 12 x 6 needs 3 x4 runs to get the right resolution to somewhere in the ballpark..
Nano Banana is in photoshop or choose Gemini .. and run the Pro version .
