posters should be eye catching which attract 1st look, message should be visible and attractive,When designing posters, it is worth noting that your work needs to get the message across quickly as there are only a few seconds for viewers to process the information. we should help you understand where to place certain elements and why they are so important.One of the biggest rules of poster hierarchy involves ensuring the size of icons and shapes is reflective of their importance. In other words, the most relevant symbols should stand out on the page. Remember, most people only ever see posters at a distance; if you have huge arrow on a poster for example, viewers will want to know why and this curiosity may cause them to take a closer look. Another way to attract the eye is through the use of colour. Not only does colour evoke feelings, it also helps distinguish what is important and what is irrelevant. With poster design, it is best to use bright and bold colours on a significant feature as this will draw the eye towards it thus ensuring it is a focal component in the design.
