The 52mm portafilter standard

52mm is La Pavoni's spec for its current-production lever machines — the stated 'filter holder internal diameter (with filter)'. Third-party tampers and baskets for these levers are commonly marketed as 51mm or 51.5mm. Neither 58mm nor 54mm parts fit, and vintage (pre-millennium) La Pavoni levers use a smaller format again.

Portafilter standards to scale. A few millimetres is the difference between a part fitting and not — a 51mm basket will not seat in a 58mm portafilter, and vice versa.
