How to set up canvas and grid pixels to be perfect

[inquestflash]

Hi community.

I have set up my document 400x 400, but when I put the guides, and turn on the grid, its not perfectly symmetrical to the smaller pixels within the rectangles are of the grid, is there a way to get it all lined up perfectly? and the cavas since its 400 x 400, why is the last large rectangle with half sqaure, and the other half out the canvas?

What units do you use?

How is your grid setup?

here's some information about the units and grid set up

Looks like that is what you get if you divide 400/72: 5,555555555555556

You could use a different Gridline Every and Subdivision.

And if the result has to be digital (web, video, image) why work in CMYK?

I would change it to RGB later on since the colour of what I want to do is black and white.

I changed the settings by Gridline every 100

and subdivisions every 10 

and it evevened out.

Good to hear that helped.

But I don't understand your "I would change it to RGB later on since the colour of what I want to do is black and white."

A CMYK black will become greyish when converted to RGB.
