Touch Targets

Optimal Touch target size and spacing help people with dexterity and mobility disabilities. A user who is elderly may not have enough motor control to focus on small links.

Touch Targets

Ensure that touch targets are at least 9 mm high by 9 mm wide. (48 x 48 dp)

Separate each target by 8dp of space on all sides

Provide inactive space around the target. The button itself could be smaller than 9mm, but the space around it is also clickable and falls within the 9mm region

Pointer Targets

Pointer targets are similar to touch targets, but apply to the use of motion-tracking pointer devices such as a mouse or a stylus. Pointer targets should be at least 44 x 44 dp.

Button Positioning

While one-handed navigation is generally beneficial for people with disabilities who have only one hand available, it greatly benefits those with temporary or situational conditions such as a broken hand, or holding a baby in one hand.

Buttons should be easy to reach, regardless of device positioning (e.g., vertical or horizontal)

Strive for flexibility. Do not assume that all users have full range of motion with thumbs, or are right-handed.

  • Some Mobile OS allow for users to temporarily shift display downwards or sideways to facilitate one-handed operation
