W3C WAI: Understanding SC 2.5.8 Target Size Minimum
Documents pointer-target minimum size and spacing expectations, including 24 by 24 CSS pixel target size, spacing exceptions, equivalent controls, and the importance of reducing accidental activation for touchscreen and other pointer users.
Pattern Decisions This Source Supports
| Pattern | Supported decision | Required contract | Claim note |
|---|---|---|---|
| Drag and drop | Choose drag and drop when the design problem is moving an object from a source to a destination, position, group, or order. | Dragging starts only from the intended handle, object, or selected set, not from unrelated scroll or text-selection movement. | Supports target size and spacing expectations for drag handles, drop targets, and equivalent controls. |
| Long press | Choose long press when the design problem is a sustained-contact gesture and its threshold, feedback, cancellation, and equivalent action path. | Long press starts only from a target that intentionally supports sustained contact. | Supports target size and spacing expectations. |
| Pull to refresh | Choose pull to refresh when the design problem is the vertical top-of-scroll drag that refreshes the current data set. | Pull-to-refresh begins only when the intended scroll container is at its top boundary and the user drags downward beyond normal scroll tolerance. | Supports target size and spacing expectations for the manual refresh control and adjacent actions. |
| Swipe action | Choose swipe action when the design problem is a horizontal item-level gesture that reveals or commits row-scoped commands. | Swipe action starts only from the intended row and horizontal axis; vertical scroll and pull-to-refresh win when movement is primarily vertical. | Supports target size and spacing expectations for revealed row actions and equivalent controls. |
| Touch gesture | Choose touch gesture when the design question is the recognition, feedback, fallback, and cancellation behavior of touch input itself. | The gesture starts only from the intended target or gesture region, not from unrelated content. | Supports target size and spacing requirements for pointer and touchscreen activation. |
