opening=* indicates the minimum width of an opening, entrance or exit of a multi-stage or chicane shaped barrier, like (motor) cycle barriers, to which the tag is added.

The value should be specified in metres (e.g. opening=1.5) following the existing specification on tagging metric values like width values. If the opening/entrance/exit widths of individual grid/barrier elements are different, only the smallest of these opening widths should be tagged since the smallest distance will determine the general passability (Example: If the "entrance" is 3 m wide and the "exit" only 2 m, use opening=2).

For simple types / designs of cycle barriers, simply specifying maxwidth:physical=* may be sufficient – see cycle_barrier=* for different designs and which tags should be combined.

Usually this key should combined with spacing=*. overlap=* could also be a suitable addition, depending on the barrier design.
