Drinking Cups, Mugs and Lids

How much it holds and what it is made of

Capacity is in fluid ounces: about 3.5 ounces is an espresso or demitasse cup, 12 ounces a standard coffee mug, and 16 ounces a large mug or tumbler. Ceramic and stoneware hold heat and feel substantial, glass shows the drink and does not stain, and double-wall stainless steel keeps drinks hot or cold for hours but cannot go in a microwave. Wine glasses and everyday glassware are measured the same way. Check the dishwasher and microwave lines before relying on either.

Lids, saucers and sets that match the cup

Travel mugs and tumblers need a lid that seals: a push-on lid resists splashes, a screw-on lid with a gasket resists leaks, and a lid with a sliding slot is for sipping rather than for a bag. Disposable portion cups and their lids are sold in cartons for food service, and a lid must match the cup's diameter and style. Coffee sets may include saucers and a metal rack. Sets are counted by piece, so read the list for cups, saucers and racks.

Questions about Drinking Cups, Mugs and Lids

Can I put a stainless steel travel mug in the microwave?

No. Metal walls block microwaves and can damage the oven. Pour the drink into a ceramic or glass mug to reheat it, and use the steel mug only for keeping a drink hot or cold.

What size mug is standard for coffee?

A typical coffee mug holds about 12 ounces, while espresso cups hold around 3 ounces and large mugs 16 ounces or more. A coffee maker's own cup measure is smaller, often about 6 ounces, so check what your machine fills.

Do glass mugs handle boiling water?

Only borosilicate or glass labeled heat resistant does. Ordinary drinking glass can crack with sudden temperature change, so pour hot liquids gently or warm the glass first. Double-wall glass keeps hands comfortable.
