The Ideal Tamper Size For Your Machine The ideal tamper should be slightly smaller than the inside diameter of the portafilter basket so that the tamper does not bind while compressing grounds - essentially there should be a little extra space between tamper and basket.

We recommend measuring the exact inside diameter of the portafilter basket and then selecting a tamper at least .75 mm smaller.
