5 best practices are to:
- Explain buttons with what they do.
- Make the important button stand out.
- Design buttons that everyone can understand.
- Avoid making too many buttons.
- Most importantly, make buttons look like they are buttons.

Studies by the MIT Touch Lab suggests that 10mm x 10mm is the best minimum size for buttons due to the average size of fingertips. Designing buttons must not only be pleasing to the eye, but they also need to make tactile sense for the user.
