Which portafilter, basket and tamper fit your espresso machine
Product links go to manufacturer sites; this site is not affiliated with any brand. How links work
Aftermarket portafilters, baskets and tampers are sold by size, and a size that is close is not close enough. This site lists the sizes each machine's accessories have to match, taken from the manufacturer's manuals and specification pages. Every figure links to its source with the date it was checked, and where a size can't be sourced, the page says so instead of estimating one.
Start with your machine
The compatibility checker shows the portafilter size, basket inner diameter, tamper and group gasket for each machine it covers, with a source for every figure.

How sizes are sourced
Each figure comes from a manufacturer manual, specification sheet or parts listing. The page links to that document and shows the date it was retrieved, and figures are re-checked on a regular schedule. Where the manufacturer publishes nothing, a figure is used only if two independent specialist retailers publish the same value; it is labelled "Retailer-published" and cites both.
Terms such as portafilter and filter basket are explained in the glossary.
