How the comparison works

Your choices are compared with each model’s product details. A missing or conflicting value stays unknown and cannot satisfy a choice you select. The starting order helps you browse; it does not rate real-world performance.

Source dates appear with each link below. A source date does not confirm today's price or stock.

The cap is part of the bottle’s size

Klean Kanteen’s capacities span 355 to 1900 ml. Cap styles are available for all 10 configurations, but shared capacity does not make their dimensions interchangeable. At 946 ml, TKWide with Chug Cap is 11.58 in high and weighs 530.8 g; TKWide with Twist Cap is 10.36 in high and 518.2 g. Both are 3.65 in wide.

At 800 ml, Reflect with Bamboo Cap is 2.9 in wide, while Wide with Loop Cap is 2.87 in wide. Capacity alone cannot answer a holder-fit question. These are Klean Kanteen’s complete-configuration measurements, without a cup-holder or leak trial.

Leave room for the holder and use the right lid instructions

Compare outer width with the actual holder opening, then consider taper, depth and the shape of the bag pocket. TKWide with Loop Cap has a 4.65 in width; Wide with Loop Cap is 4.34 in wide at the same 1900 ml capacity. A width filter narrows candidates but cannot prove the bottle will seat securely.

Follow the selected cap’s restrictions for hot, carbonated or other liquids. Neither a cap name nor a capacity figure tells you which drinks are permitted, and exchanging caps changes the configuration you originally compared.

Before you buy

Why are there two 32 oz TKWide bottles?

They differ by cap. With the Chug Cap it stands 11.58 in tall and weighs 530.8 g; with the Twist Cap it's 10.36 in and 518.2 g, so the cap you pick changes how it sits in a holder.

Can I put hot or fizzy drinks in the Twist Cap bottles?

Not without reading Klean Kanteen's instructions for that cap first. All three Twist Cap bottles come with a steel straw, per their page titles, and cap limits for hot or carbonated drinks aren't part of this comparison, so keep hot and fizzy drinks out until the maker's instructions say otherwise.

Will a bottle fit any holder wider than the bottle?

Not necessarily. Widths here run from 2.87 in on the 27oz Wide to 4.65 in on the largest TKWide below, but a holder's taper, depth and opening shape decide the fit, so measure the holder as well as the bottle. Nearly three times, at 64 oz. Klean Kanteen's insulated TKWide weighs 836.3 g and the Non-Insulated Wide 292.6 g, both holding 1,900 mL. All five TKWide bottles are titled Insulated; even the 355 mL one weighs 329.1 g. If weight matters more than insulation, the 800 mL Wide, Classic and Reflect, none titled Insulated, weigh 213.6 to 243.7 g.
