Travel cups commonly range from about 10 ounces up to 40 ounces. Individual options mentioned in listings include sizes such as 11 oz and 20 fl oz, with other sizes available within that general range.
Many travel cups are made from stainless steel (often food‑grade 18/8 stainless steel). Components for children’s cups and some lids or seals are also made from plastics and silicone.
Travel cups often advertise leakproof or spillproof lids and valves — for example, leak‑proof slider lids and one‑way valve straw lids. In practice, most are spill‑resistant when lids are assembled correctly; misassembly or damaged parts can still cause leaks, so follow manufacturer instructions and check seals regularly.
Common lid types include slider lids, straw lids (often with one‑way valves), flip‑top lids, twist‑off lids, and multi‑position screw‑on lids that offer separate straw and drink openings or multiple sip modes.
Kid‑focused cups typically have smaller capacities, removable or peel‑open straws for easy cleaning, one‑way valves or spillproof features to reduce leaks, and sometimes soft bases or small handles to help kids hold and stabilize the cup.
