How big should a button be UX?
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.
Should buttons be all caps?
Majority of systems do capitalize, or use title case on buttons labels. This may help in making button labels stand out as stand alone actions that aren't full sentences (e.g. Ask Question, Edit Details, Save Changes).
