Increase/Decrease Material Size on Surfaces

I selected a brick material to add to my project and I added it to a piece of geometry but the brick material is really small and looks odd, is there any way I could increase the size of the brick material or for someway for it to zoom in?

You can control the tiling amount by multiplying the TextureCoordinate node with a number (to control how much it is tiling) and hooking that up into all your textureinputs. If you show an example it is easier to pinpoint your problem. It sounds like either you have too many bricks in your texture or your wall unwrap is too big.

Another more cheaty way is too look into WorldAlignedTextures. There should be enough material on youtube to help you on your way.
