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.
How do I know what size tamper I need?
- Measure the portafilter across the diameter (the centerline).
- Change your reading to a decimal unit
- Convert the inches to millimeters by multiplying by 25.4 (2.33 x 25.4 = 59.18 mm)
- Get a tamper that’s 0.75 mm smaller by subtracting (59.18 – 0.75 = 58.43 mm)
