The clear space is to ensure that the Serco brand retains its integrity and strength within the medium it is being used.

The clear space (indicated by the solid line) is the minimum area around the Serco logo that must remain clear of typography or any other graphic device. 

The formula for the clear space is shown here and applies to all sizes of identity reproduction. It is calculated by using the size of the ‘O’ in the Serco wordmark and varies in direct proportion to the size at which the logo is reproduced.
