A laptop's product page tells you the processor and the price. It rarely tells you how wide the machine is, whether the memory can be replaced, or whether there is a real network port. We read each maker's specification document and re-type those facts into one catalogue: 29 current chassis so far, from Lenovo, Apple, Dell and ASUS, with more brands being added.

## Size and weight

We don't test laptops. Dimensions, ports, memory and battery capacity come from the manufacturer's document for each chassis; measured performance and battery life belong to labs that measure them, and we link to those where it matters. A dash in any table means the document doesn't say, and we don't guess.
