Filing & organisation

Lever arch or ring binder?

A lever arch file uses a two-ring lever mechanism and holds a lot of paper, typically several hundred sheets, so it's the workhorse for household records and archives. It sits upright on a shelf and has a finger hole in the spine for pulling it out.

A ring binder is slimmer, with two or four rings, and is better for things you flick through often, such as course notes, recipes or a project file. Four-ring binders keep pages flatter and less likely to tear. D-ring binders hold a little more than round rings of the same size.

Pockets, dividers and wallets

Punched pockets (clear plastic sleeves with holes along one side) protect documents you don't want to hole-punch, such as certificates or letters you might need to scan. Index dividers, numbered or tabbed, split a file into sections. Expanding files have concertina pockets and a flap, good for receipts, warranties and anything you need to carry.

UK filing is built around A4 and the standard two-hole punch spacing of 80mm, so check that folders and pockets match.
