The best travel mugs for one person hold a single serving of coffee or tea, usually 12 to 20 oz, and fit a car cup holder. This guide covers six insulated stainless steel mugs in that range: two 12 oz mugs, two 16 oz mugs, an 18 oz mug and a 20 oz mug. They differ in lid style, handle, hold time and how you clean them.
Every detail here comes from each product’s Amazon listing, and we did not test these travel mugs in person. Scores follow the four criteria in the How We Score section, and our Editorial Policy explains how we handle listing data.

How to Choose the Best Travel Mug for One Person
Match the size to one serving
A 12 oz mug suits a small cup of coffee, while 16 to 20 oz gives you a large mug or a refill. The picks here run from 12 oz to 20 oz.
Compare the listed hold times
Hot hold times range from 2 hours to 8 hours across these listings, so check the number if your drink sits for a long commute or a workday.
Choose a lid you can use one handed
Slider, flip top and drink through lids all open differently. Pick the style you can work while driving or walking, and check that the listing calls it leakproof.
Check the base width and height
Compare the listed base width with your car cup holder. The listings here give base widths from 2.9 to 3.6 inches, so measure your holder if it is narrow.
Read the cleaning notes
Some mugs go fully in the dishwasher, some only the lid and some are better rinsed by hand. A wide mouth also makes hand washing easier.
