As in any profession you need somewhere to work. Pick somewhere quiet to setup preferably either loft or basement. Any room will do so long as there is sufficient light and power points. A one desk setup is the minimum a Graphic Designer could use comfortably especially if you’re just starting out. Also make sure you have a comfortable chair, standard or executive providing lumbar support for your back. OK, choose your weapon! Mac or PC? This is a matter of choice, both types of machine can provide excellent results using cross-platform software. The operating systems also share some compatibility between each other which is a big benefit for all Designers. A reasonable size monitor 18” and above can be used with your setup, including a comfortable keyboard and mouse. Some Designers also have a Graphic Tablet which although once thought to be an expensive market, the price for entry level graphic tablets has come down considerably. You will need at least an A3 size space on your desk for books and materials. Keep your work area tidy! This will help you stay organised and efficient a necessary standard for any Graphic Designer. I have a lot of reference material (Morgue files) and books close to hand along with paper, pens, pencils, etc. Choose your design program and learn it. Stick with it and try not to change to another program unless you find it impossible to use.
