Safe standing is a measure of design in stadia to ensure that spectators are able to stand safely during events. It is important in the context of association football in the United Kingdom, where a series of fatal incidents led to legislation requiring major clubs to develop all-seater stadiums during the 1990s. Since then, fan groups have campaigned against the ban on standing accommodation, arguing that new design options would allow designated standing areas to be built in compliance with all safety laws and guidelines. As these options are outlawed in England and Wales, safe standing in practice originated in continental Europe, primarily Germany. This occurred because although UEFA and FIFA required all-seater stadiums for international competition, it was not mandatory for domestic matches.

A terrace or terracing in sporting terms refers to the standing area of a sports stadium, particularly in the United Kingdom and Republic of Ireland. It is a series of concrete steps, with intermittent safety barriers installed at specific locations to prevent an excessive movement of people down its slope.
