Portafilter, basket, tamper, puck screen and funnel sizes for 19 machines, with the source for each figure. No prices and no affiliate links on this page.
The reason it exists: most “54 mm” machines do not take a 54 mm tamper. Stock baskets taper toward the base, so a true 54 mm tamper binds on the wall about 0.7 mm above the coffee — a gap you cannot see by eye, which is why so many tampers get returned. 53.3 mm is the size that fits. The Lelit Anna is a second trap: 57 mm, one millimetre off the commercial 58 mm standard, so nothing from the 58 mm aftermarket fits it.
Every size below comes from one of these. Manufacturer pages first, then specialist retailers and community threads where the manufacturer does not publish the figure.

Machines are listed only where more than one independent source agrees, and rows say so where sources conflict. Makers change formats without renaming models — check your own manual before buying.
Barista Express: Built-in grinder: some magnetic dosing funnels block the auto-dose cradle. Check the listing says it clears the grinder.
Barista Express Impress: The assisted tamp mechanism expects the stock basket depth — precision baskets can change the tamp feel.
Barista Pro: Built-in grinder: check dosing funnels clear the auto-dose cradle.
Barista Touch: Sources conflict on this model. Most retailers list it in the 54mm family; confirm against your manual before buying.
De’Longhi Dedica / Dedica Arte (EC680 · EC685 · EC885): The Dedica ships with a pressurised basket, which masks grind quality. Moving to a non-pressurised 51 mm basket is the usual first upgrade — but it only pays off once you have a real grinder.
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.
De’Longhi Linea Classic (EM450M): Sold with pressurised baskets. The 51 mm parts that fit the Dedica fit this machine too, but check the listing names your model — De’Longhi uses more than one portafilter format across its range.
Profitec GO: Shares the Profitec 58 mm portafilter with the Pro 300 / 400 / 500 / 600 / 700, so parts are interchangeable across that range.
Profitec MOVE: E61-group machine, so it takes the same 58 mm portafilter as the rest of the Profitec E61 range.
De’Longhi’s 51 mm is its own ecosystem. Parts sold for Breville (54 mm) or prosumer machines (58 mm) will not fit, so filter every listing by 51 mm.
| Part | Size | Why it matters |
|---|---|---|
| Portafilter | 51 mm | De’Longhi uses its own 51 mm size. Neither 54 mm (Breville) nor 58 mm (commercial) parts will fit. |
| Filter baskets | 51 mm | ★ The stock basket is pressurised — it forces crema regardless of grind, which hides both good and bad grinding. A non-pressurised 51 mm basket is the standard upgrade, but only makes sense with a real grinder. |
| Tamper | 51 mm | Must be 51 mm. The plastic scoop-tamper in the box is the single biggest limiter on this machine. |
| Dosing funnel | 51 mm | Sits on the portafilter rim so grounds do not spill. |
| Puck screen | 51 mm | Sits on top of the puck. Sold for the Dedica in 51 mm, typically around 150 µm mesh. |
| Distribution / leveller | 51 mm | Levels the grounds before tamping. Adjustable-depth versions let you match the shallow 51 mm basket. |
| WDT tool | Universal | Needles break up clumps. Not size-specific — and it matters more here than on any other machine, because the basket is small. |
| Knock box | Universal | Not size-specific. |
| Scale | Slim preferred | The Dedica is very narrow with little clearance under the spouts — a slim scale fits best. |
Accessories are shared across this whole family. Anything sold for the Barista Express, Barista Pro or Bambino will fit the Bambino Plus, and vice versa.
| Part | Size | Why it matters |
|---|---|---|
| Portafilter | 54 mm | Bottomless (naked) portafilters for this family are 54 mm. A bottomless basket shows channelling you cannot see otherwise. |
| Filter baskets | 54 mm | Stock sizes run roughly single 8–11 g, double 16–18 g, triple 18–22 g. Precision baskets (IMS, VST) are made in 54 mm for this family. |
| Tamper — stock basket | 53.3 mm | ★ The single most common mistake. Stock Breville baskets have slightly tapered walls, so a 53.3 mm tamper is the correct fit — not 54 mm. |
| Tamper — precision basket | 54.0 mm | Precision baskets have straight walls, so they take a true 54.0 mm tamper. Note that some brands also sell 54.3 mm in this family — that extra third of a millimetre is enough to catch on the wall in some basket and tamper combinations, so 54.0 mm is the safer default unless a maker states otherwise for your exact basket. |
| Dosing funnel | 54 mm | Magnetic funnels sit on the portafilter rim. On machines with a built-in grinder, check it still clears the auto-dose cradle. |
| Puck screen | 53.3 mm | Sits on top of the puck. Sized slightly under the basket so it drops in — 53.3 mm, not 54 mm. |
| Distribution / leveller | 53–53.3 mm | Levels the grounds before tamping. Same tapered-wall logic as the tamper. |
| WDT tool | Universal | Needles stir the grounds to break clumps. Not size-specific — any WDT works. |
| Knock box | Universal | Not size-specific. |
| Scale | Check clearance | Any timer scale works, but the Bambino/Bambino Plus drip tray is shallow — a slim scale fits better under the spout. |
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.
| 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. |
| Filter baskets | 57 mm | Sold as LELIT57. Fewer precision-basket options exist than for 58 mm — check the listing states 57 mm explicitly. |
| Tamper | 57 mm | A 58 mm tamper will not seat correctly. Buy 57 mm. |
| Dosing funnel | 57 mm | Match the portafilter size, not the commercial standard. |
| 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. |
| 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”. |
| WDT tool | Universal | Not size-specific. |
| Knock box | Universal | Not size-specific. |
| Scale | Universal | Any timer scale works. |
58 mm is the commercial standard, so most third-party tampers, baskets and screens made for prosumer machines will fit.
| Part | Size | Why it matters |
|---|---|---|
| Portafilter | 58 mm | These machines use the commercial 58 mm standard, so the whole aftermarket is open to you. |
| Filter baskets | 58 mm | Typically 18–22 g doubles. IMS and VST precision baskets are widely available in 58 mm. |
| Tamper | 58.0–58.5 mm | 58.5 mm gives a tighter fit in most 58 mm baskets; 58.0 mm is the safe default. |
| Dosing funnel | 58 mm | Magnetic ring that sits on the portafilter rim. |
| Puck screen | 58.5 mm | Sits on top of the puck to keep the shower screen clean. |
| Distribution / leveller | 58 mm | Levels grounds before tamping. |
| WDT tool | Universal | Not size-specific. |
| Knock box | Universal | Not size-specific. |
| Scale | Universal | These machines have deeper drip trays, so scale height is rarely a problem. |
A puck screen sits on the coffee, inside the basket, so it has to drop in rather than seat on the rim — and the size sold for each group reflects that rather than the group's nominal number. Three of the four are not the number on your machine.
| Group | Basket | Puck screen | |
|---|---|---|---|
| 51 mm De’Longhi group | 51 mm | 51 mm | Matches the basket. |
| 54 mm Breville / Sage group | 54 mm | 53.3 mm | 0.7 mm under the basket, so it drops inside rather than sitting on the rim. |
| 57 mm Lelit group | 57 mm | 57.3 mm | Sold 0.3 mm over the nominal 57 mm — check the figure, not the machine's name. |
| 58 mm commercial-standard group | 58 mm | 58.5 mm | Sold 0.5 mm over the nominal 58 mm — check the figure, not the machine's name. |
So the rule that works for tampers — go under the nominal size — does not carry over. For the 54 mm group the screen is under; for the 57 and 58 mm groups it is over. Read the figure for your group rather than converting from the machine's name.
What this page does not tell you is whether a puck screen improves the shot. That question is argued about at length and I have not found a source solid enough to cite either way, so it is not answered here. Sizes are checkable; that is what this page is for.
