What fits a 57 mm Lelit
By Lin · How we pick · Full Fit Finder
One millimetre is enough to make an entire aftermarket useless to you. Lelit’s 57 mm format sits just inside the 58 mm commercial standard, so the tampers, baskets and bottomless portafilters that fit almost every prosumer machine will not fit yours. Listings rarely make this obvious — most say “fits most espresso machines”, and that means 58 mm.
Machines in the 57 mm group
- Lelit Anna (PL41) — ★ 57 mm, not 58 mm. Lelit’s 57 mm format (LELIT57) is one millimetre off the commercial standard, so 58 mm tampers, baskets and bottomless portafilters will not fit. The aftermarket is noticeably narrower — check every listing says 57 mm.
Every size for this group
| Part | Size | Why it matters | |
|---|---|---|---|
| Portafilter | 57 mm | ★ One millimetre off the 58 mm commercial standard. A 58 mm portafilter will not fit, and this catches people out constantly. | Find one ↗ |
| Filter baskets | 57 mm | Sold as LELIT57. Fewer precision-basket options exist than for 58 mm — check the listing states 57 mm explicitly. | Find one ↗ |
| Tamper | 57 mm | A 58 mm tamper will not seat correctly. Buy 57 mm. | Find one ↗ |
| Dosing funnel | 57 mm | Match the portafilter size, not the commercial standard. | Find one ↗ |
| Puck screen | 57.3 mm | ★ Note the figure: puck screens for this group are commonly sold as 57.3 mm, not 57.0 mm. Sized to drop inside the basket. | Find one ↗ |
| Distribution / leveller | 57.35 mm | ★ Lelit’s own leveller (PLA472A) is specified at 57.35 mm. This group is sold under 57, 57.3 and 57.35 mm depending on the part — read the exact figure on every listing rather than assuming “57”. | Find one ↗ |
| WDT tool | Universal | Not size-specific. | Find one ↗ |
| Knock box | Universal | Not size-specific. | Find one ↗ |
| Scale | Universal | Any timer scale works. | Find one ↗ |
The 57 mm Lelit format has a genuinely narrower accessory market than 58 mm — owners on Home-Barista describe hunting for parts as the main frustration of the machine. Two things follow. If a listing only says “fits most prosumer machines”, assume it means 58 mm and skip it. And read the exact number: parts for this group appear as 57, 57.3 and 57.35 mm depending on what they are.
