Paper lid or sipper lid

A paper lid seals for carrying. A sipper lid has a drinking aperture, for a drink consumed on the move. Most lid questions we get come down to that one line.
Which sizes each one fits
Paper lids fit 200 and 250 ml glasses, and one paper lid closes both 350 and 450 ml. Plastic sipper lids fit 150, 200, 250 and 350 ml. Neither fits the small tea sizes, which are drunk on the spot, or the 300 ml glass.
Order the lid by the glass it closes, not by the lid's own size. The products page has the full compatibility matrix.
Choosing between them
A cloud kitchen sending a drink out with a rider wants it sealed, so a paper lid. A café handing a coffee to someone walking to the station wants them to drink through the lid, so a sipper. At 200, 250 and 350 ml both lids fit, so one glass can go out either way.
Lids are not printed. The brand goes on the glass.
