# Creating right canvas size for a project

I have a project wherein I need to create a banner with a size of 205cm x 445cm. When creating a canvas for this size do I need to convert it in inches first then set the resolution to 300 pixels/inch or is it okay to just convert it directly to pixels?

When converted to inches:

455cm = 175.197 inches
205cm = 80.7087 inches


When I view the image size of this canvas I get 52559 pixels width and 24213 pixels height.

When coverted directly to pixels

205cm = 7748 pixels
445 = 16818 pixels


What canvas size do I follow when creating project like this?

• Pixels don't have an actual size, their size is relative to the screen they are being viewed on.

• This project will be printed once done. When i use inches and set the resolution to 300 my computer is having a hard time because the file is too big. Does it affect the quality of the banner when i use the converted pixels instead of the inches? Commented May 28, 2018 at 2:15
• I think this question has been asked before - see What resolution should a large format artwork for print be? Commented May 28, 2018 at 7:47

Note you can leave the Resolution field set to Pixels/Inch and input 300. Photoshop will do the calculation for you.
