W.A. Thow's 1984 publication entitled "The Rings of Twelve" listed details of some 85 such rings. The intervening years have seen twelve-bell ringing continue to flourish in many centres and through subsequent augmentations, the total number now stands at 145.

Until 1991 Twelve was the maximum number of bells used in a diatonic change-ringing instrument; in that year the first augmentation beyond twelve was realised with the installation of a ring of Sixteen at St Martin's Birmingham. Two further Sixteens now exist: at Perth (Western Australia) and Christ Church Cathedral, Dublin, as does a ring of Fourteen at Winchester Cathedral.
