About espressosizes.com

espressosizes.com is a reference for home espresso accessory sizes: which portafilters, filter baskets, tampers and gaskets fit which machines.

Every measurement is cited on the page where it appears, with the date it was last checked. Where a manufacturer publishes nothing, a figure is used only when two independent specialist retailers publish the same value, and it is labelled "Retailer-published" with both citations. Otherwise the page says the figure is not published rather than estimating one.

Pages are written with AI assistance and checked against the cited manufacturer documents before they are published. The site does not test, review or rank products.

This site is not affiliated with any brand. Brand and model names are used only to identify products.
