Know the width of the file that you will be using the grid for. For instance, have a target file that is 1400 * 1400 pixels.
2
Open a new file. Go to File >> New or CTRL + N. Set an appropriate size for the target image that you are going to use the grid in. 1400 is the example here, so the size will be 50 * 50 so that it can be seen.
