IMS's 'For tamper 58 / 58.4' B70 basket compatibility list names ROCKET — a basket maker's published (measured) fitment placing Rocket-brand machines in the 58mm standard. This is the measured basis for the diameter here.

Presents the Giotto Fast as part of 'Rocket's dual-boiler legacy' — a PID, dual-boiler E61 domestic machine (1.8 L boiler, rotary pump, plumb-in or reservoir). The catalogue does not print a portafilter diameter for the Giotto specifically, which is why this sits at the measured tier rather than manufacturer-verified.
