Which kind are you buying?

This is the index of every kind of product on the site. Each card is a category, and each names the one measured figure that changes most between the products in it, so you can see before you click which number to compare.

Choose the kind first, then the number that decides it. For an espresso machine, decide whether the grinder is built in or bought separately, then check width against your counter. For a grinder, choose hand or electric, then check height against the space under your cabinets. A scale has to be small enough to sit on the drip tray under the cup. A kettle is chosen by how much water it holds and whether it keeps a set temperature, and a filter brewer by the cups it makes at once and what it sits on. Station furniture is chosen by footprint and load, then height against the cabinets. Accessories have to fit what you already own, such as a tamper sized to your basket. Coffee beans have no width, so roast level and origin decide.

Each card opens a category page with every product in it, as a list and as a side-by-side spec table that shows where each figure comes from. If you already know the product, the folded list at the foot names every one.
