What are the target area best practices for touch interfaces?

Consider making touch targets at least 48x48dp, separated by 8dp of space or more, to ensure balanced information density and usability. A touch target of 48x48dp results in a physical size of about 9mm, regardless of screen size. The recommended target size for touchscreen objects is 7-10mm.

What button width is best practice?

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.

How do I increase my touch target size?

If you are adjusting your CSS within a media query to increase the touch target, testing for a coarse pointer allows you to increase the tap targets for all touchscreen users. This gives the larger tap area whether the device is a phone or larger device.

What is the ideal padding for buttons?

Button padding is one of the most important aspects of button styling. My personal styling is to set vertical padding equal to font height, and set horizontal padding to 1.33 times vertical height. If a font height is 20px, vertical padding is 20px, and horizontal padding would be 27px.
