Plan for edge cases

Edge cases represent scenarios that fall outside typical use but will inevitably occur. Empty states, error messages, and unusual content lengths all require planning during wireframing. Anticipating these situations prevents awkward experiences during user testing and production use.^[1]

Error text placement deserves specific attention in wireframes. Field validation messages, system notifications, and confirmation dialogs all need designated locations. Wireframes should show where these messages appear and how they interact with surrounding content without causing layout shifts.

Accessibility considerations should also be part of edge case planning. Alt text for images, proper link descriptions, and button labels that make sense without visual context all improve the experience for users relying on assistive technology. Including these details in wireframes ensures accessibility is built into the product rather than added as an afterthought.
