Laptops: sizes, ports and memory, from the makers' spec documents
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.
