Photoshop Max Document Dimensions

[steve_tiano]

What is the maximum allowable dimensions, in inches, a document can be in Photoshop? Is this different from InDesign's maximum allowable page dimensions?

Thank you.

Photoshop's limit is in pixels. Inches can be different depending upon the resolution, so that is arbitrary. The pixel limit is 300,000X300,000, according to this link:

It would depend on the resolution.

So 300,000 / ppi

at 600ppi - 500 inches

at 300ppi - 1000 inches

at 200ppi - 1500 inches

at 100ppi - 3000 inches

and so on.

In Designs max page size is 216 inches.
