Hello Everyone,
Started by taking a new document of size w-20 Inches & h-30 inches
Then when I gone to the canvas size, its showing w-20.002 & h-29.998
also when I'm watchingat my properties pannel its showing 20*30
I'm not able to understand this problem.
I've attached the screenshot. please let me know if anyone can solve this.
An image is just a rectangular collection of pixels. These pixels don't actually have a physical size. An image only takes on a physical size when we assign a resolution to it and thus define how many pixels per inch (PPI) there should be.
It looks like you are using 72 pixels per centimetre. Just wanted to confirm that you shouldn't be using pixels per inch.
If you really want to nerd out...
1 inch = 2.54cm
20 inches = 20 x 2.54cm = 50.8cm
50.8cm x 72 pixels per cm = 3,657.6 pixels

I've created a 20 x 30 inch document and checked every setting as you have shown in your screen shots and can't make this happen. What are your system specs and have you completely restarted your computer and photoshop? Can you make a screen recording of your steps?

1 inch = 2.54cm
20 inches = 20 x 2.54cm = 50.8cm
50.8cm x 72 pixels per cm = 3,657.6 pixels
Can't have a fraction of a pixel so 3,657.6 becomes 3,658 pixels
3,658 pixels / 72 pixels per cm = 50.8055556cm
50.8055556cm / 2.54 = 20.0021872 inches = 20.002 inches (to 3 decimal places)

@Michael Bullo - right on! When I change to pixels per centimeter I can create the same canvas size.
