Systems and methods for keypad button resizing are disclosed. In some implementations, a keypad including multiple characters is displayed on a display of a touchscreen device. A selection of one of the multiple characters on the keypad is received. For each character in the multiple characters on the keypad, a likelihood value that the character is a next character to be typed is predicted and a button size for the character is selected based on the predicted likelihood value. The keypad is modified based on the selected button size for each character. The modified keypad is displayed on the display of the touchscreen device.
