To become a graphic designer, there are a variety of courses available, and each course varies in length from a few weeks to a few months, and even a few years depending on what is included in the course. Consider courses which include graphic design, communication design, art and design, and illustration in their course content to obtain a variety of skills. Once you have enrolled in a graphic design course, and you have the basic skills and knowledge, begin freelancing with individuals and companies to build your portfolio. Continually build on that portfolio until you are ready to begin your career. Your portfolio is a showcase of your work, so having it available to potential employees can show your skill from the get-go.
