As you travel down most urban roads or rural highways, you will likely see one of the most high-impact outdoor advertising methods available to advertisers: billboards.

 

Billboards provide companies with a larger-than-life way to promote products to thousands of people on a daily basis. They are designed to catch the attention of customers and leave a memorable impression very quickly. Unlike other advertising methods, billboards have only the few seconds it takes for the commuter to pass to make an impact.

 

Obviously, working on a full-sized mock-up of a billboard in the design planning stages would be a huge task, not to mention very expensive and time consuming. So designers use scale diagrams to produce accurate and proportional representations. Scale diagrams provide an accurate sample and allow for changes to be made efficiently and inexpensively and help create advertisements with impact and visual appeal.

 

This lesson will help you answer the following critical questions:

  • How can scale diagrams and models be used to determine unknown measurements?

  • How can scale factor be used to create scale diagrams?
