I got an urge to do something with a lot of typography to practice my grid ability and really improve it. Grids should constantly be used in design, even if something is not directly grid based. If design is uneven and not fitting within the grid, the design is regarded at as bad. Now yes, some design is not supposed to be grid based, but if something is, which most of my design is, you have to make sure everything is lined up and fitting within the grid. Logos a lot of the time are not grid based, and other things are just centered on the page, which doesn’t call for guides. Whenever you have a lot of type on top of each other and next to each other, use grids. You can use guides to set up your grid in Illustrator and Photoshop, and I would challenge you to use them in your designs.
