In the catalogue, printers´ marks against the chart number indicate whether a chart is in the international Chart Series, or whether on ARCS or Leisure Edition of the chart is available. The title of a chart is listed as given on the chart itself; alternative or secondary names are in brackets. If a chart has inset plans, details are listed below those of the chart itself. In the case of a sheet of plans, the details are listed below those of the chart itself. in the case of a sheet plans, the details are listed below the general title of the chart.

The size of the majority of Admiralty charts is about 980 x 640 mm, measured between the inner neat-line; these charts are sold single-folded. A small number are half this size, corresponding to the folio size of 710 x 520 mm, and are sold unfolded, increasingly, Admiralty charts are produced to International AO size (841 x 1189 mm); these are folded twice to bring them to the folio size. The size of various miscellaneous charts and diagrams listed in part 3 vary. A few are necessarily larger than single-folded size (for example, to provide cover from one major navigational feature to another, or to comply with on internationally agreed format) but these are folded again to bring them to the folio size.
