Build:Space Station Size
11.1 Size
Space stations are considerably larger than starships. For the purpose of Spacedock calculations, consider the station to be eight sizes larger during the design process than its actual rating. (Ex: Deep Space Nine is a Size 4 station, but it considered to be a Size 12 during the design process.) This applies to all design calculations except for the bridge (referred to as the Operations Center for stations).
The station's mass and SUs are determined by Table 3.1: Vessel Size Scale. Physical dimensions may also be taken from this table. However, stations with an open style of construction, such as Deep Space Nine, will have larger overall dimensions, so move a line (or two) down the table to reflect the dimensions of such a station. Conversely, stations with a compact design, such as (the actual) Spacedock, will have smaller dimensions, so move up a line (or two) on the table.
