# Which tamper size fits your machine?

> What size tamper you need — 58, 57, 54 or 52mm — why it must match your portafilter, and the tampers we cover with the machines each fits.

A tamper has one job: press the coffee into a level, even puck across the *whole* basket. So it has to **match your basket's diameter** — a tamper that's too small leaves an untamped ring around the edge where water channels straight through, and one that's too big won't enter the basket at all. The rule is simple: **buy the tamper size that matches your portafilter**.

## Match the tamper to your portafilter size

Tampers are sold by the portafilter standard they're made for. The four you'll meet on common machines:

- **58mm** — the commercial standard (La Marzocco, Rancilio, Lelit's 58mm line, Gaggia, most E61 machines). The most common tamper size.

- **57mm** — Lelit's LELIT57 line (Anna, Diana). One millimetre narrower than 58, and not interchangeable with it.

- **54mm** — Breville / Sage home machines. A 58mm tamper will not fit (see [why 58mm doesn't fit Breville](https://espressofit.com/guides/breville-54mm-vs-58mm/)).

- **52mm** — La Pavoni's current levers. Third-party tampers for these are often marketed as 51 or 51.5mm; the basket body is the thing to match, so check the machine's page.

A snug tamper is worth it: the closer it is to the basket's inner wall, the more even the puck. Precision tampers are therefore cut to a tolerance rather than to the round number, and the makers publish it: IMS recommends "a precision tamper sized between 58.4mm and 58.5mm" for its 58mm baskets, and VST specifies "58.40 +0.00 -0.05mm diameter flat face" for its 15g and larger sizes. You still buy by the nominal size, so a "58mm" machine takes a "58mm" tamper — the decimals are the manufacturing spec, not a different product.

## How we verify

Each tamper's size and fitment is quoted from the maker's own listing on its entry. See [how we verify compatibility](https://espressofit.com/methodology/) or the [portafilter sizes guide](https://espressofit.com/guides/portafilter-sizes/).

The two tolerance figures quoted above come from the manufacturers directly: IMS states "we highly recommend using a precision tamper sized between 58.4mm and 58.5mm" on its [Rancilio](https://www.imsfiltri.com/rancilio-precision-filters-showers.html) and [Rocket](https://www.imsfiltri.com/rocket-espresso-precision-filters-showers.html) compatibility pages, both read firsthand 2026-08-23; VST gives "58.40 +0.00 -0.05mm diameter flat face tamper" for its 15g through 25g baskets on its [own store page](https://store.vstapps.com/products/vst-precision-filter-baskets), read firsthand 2026-08-23.
