Mobile devices are the hardest to design for, but why? First, look at the most obvious indicator, screen size. An average laptop has a 13 to 15-inch screen. The average phone has a 5 to 7-inch screen. Straight and simple, the desktop devices have more real estate to add your design elements, CTA (call to action), and other features.
Another major indicator is functionality. A mouse does not function the same as someone’s finger. The cursor on a desktop is very precise when it comes to clicking on links or buttons. When designing for desktops we don’t need to put much thought into spacing around clickable elements. However, when using a mobile device your finger is not as precise as a cursor. This causes problems with poorly designed mobile experiences that don’t take into account most people browse websites using their fingers on mobile devices. To solve this issue, you must design your mobile website with larger and easily accessible touch points.
