Find a listed part
Start with your exact machine.
Match the model code on the machine label or manual. These records cover U.S. versions.
Browse all 19 machine records ↓Choose a machine to see its size and listed parts.
Check this first
Size is the first check.
A portafilter holds the filter basket and locks into the machine. Two holders can have the same diameter and different locking tabs.
- Match the machine. Check its full model code.
- Match the part. Look for a manufacturer fit listing.
- Check the basket. Its depth, rim, and tamper clearance also matter.

The full reference
Portafilter sizes by machine
A matching diameter does not confirm fit. “Exact model listed” means the maker names the model code. “Model family listed” is a broader claim. These are source checks, not physical tests. Each row links to its size source and each part’s fit source.
Amazon links here are affiliate links. They open Amazon search results, not verified listings, so check the exact part and fit. Source prices are not Amazon quotes.
Three separate fit checks
What a size label can tell you
“54 mm” describes a size family. It does not describe every surface that must fit.
Decide whether a bottomless portafilter is worth it →- Portafilter → machine
- Check the exact holder and model code. The locking tabs must match the machine’s group head. Tab shape, thickness, and position can differ at the same diameter.
- Basket → portafilter
- Check the basket rim and depth against the holder. A deep basket may not clear a spouted holder. A pressurized system can have additional fit requirements.
- Tamper → basket
- Use the basket maker’s recommended tamper size. A nominal 58 mm system does not tell you whether a 58.0, 58.4, or 58.5 mm base will move freely.

How we checked
Source review, with clear limits
We reviewed 15 manufacturer or official regional product pages. We recorded the published size and expanded compatibility lists where available. We matched only the named codes or the stated model family. We did not transfer compatibility by brand, diameter, or a related-product link.
This release covers 19 selected U.S. machine models and 9 parts. It is not a complete accessory catalog. It does not cover modified group heads, every regional revision, or all replacement baskets. A listed match can change if the maker revises a part.
We have not physically tested these pairs. Check the current manufacturer listing before purchase. If a source changes, its dated record needs a new review. Report a correction or request a model.

Portafilter fit questions
What portafilter size does the Breville Barista Express use?
The U.S. Barista Express BES870 uses the listed 54 mm system. Breville names BES870 for its BEA204WLW0ZNA1 naked portafilter, BEA202WLW0ZNA1 tamper, and SP0001520 two-cup single-wall basket. A generic 54 mm label does not establish fit.
Do the Bambino and Barista Pro use the same size?
Breville lists 54 mm parts for the U.S. Bambino BES450, Bambino Plus BES500, and Barista Pro BES878. The reviewed Breville holder, tamper, and basket listings name all three. Check the exact accessory code, especially if you replaced the original basket.
Will any 58 mm portafilter fit a Gaggia Classic Pro E24?
No universal match is established by a 58 mm label. Gaggia lists a 58 mm portafilter for the Classic Pro E24, but the reviewed Gaggia bottomless accessory page does not publish an exact model fit list. Confirm the holder and machine revision with Gaggia before buying.
Is a 54 mm basket a 54 mm tamper specification?
It is a size family, not an exact clearance measurement. A tamper must move inside the basket without binding. The basket's internal shape and the tamper's actual base size matter. Use the basket maker's tamper specification for a precision replacement.
Which portafilter fits the Ninja Luxe Café?
SharkNinja lists replacement portafilter 562UO600 for the Luxe Café Premier ES601 and Pro ES701. The reviewed part page does not state a diameter or confirm a bottomless replacement. This finder preserves that distinction.
Will the De’Longhi DLSC085 fit every 51 mm machine?
The maker lists the La Specialista and Dedica Maestro families. That claim covers the families used by EC9250M and EC950M in this chart. It does not establish fit for Stilosa, every Dedica model, or another brand's 51 mm machine.
