Produced as a woodcut, i.e. the details cut into a block of wood before printing, the map was always in the same size and format as the very wood block used: 41 x 29 cm in stereographic projection to a scale of about 1:5,600,000.

The dots used on the map are mile-indicators for actual travelers to Rome - or for travelers of the mind.
