Excel is very useful to a variety of different types of people, making it meet the principle of equitable use. For example, Excel can be useful to teachers, students, business workers, moms and dads on a budget, etc. Excel can create simple spreadsheets, graphs, tables and can also generate percentages, formulas. Excel also has a low physical effort, meaning it is not too difficult to use and does not require much effort to understand. The rows and columns are also re-sizable for whatever the users wanted size. This type of technology does not meet the size and space approach and use design since it does not require any additional components (in a physical way) to accommodate to a user’s body size, posture, mobility, etc.
