Shopping for a Stanley tumbler boot and not sure which size to grab? You're in good company. "Will this boot fit my cup?" is the question we hear most, whether it's about a 40 oz Quencher, an Owala FreeSip, or a big 64 oz jug. This Stanley tumbler boot size guide walks through every size we carry, which cups each one is made for, and how to finish the look with a charm and a bow.
Stanley Tumbler Boot Size Quick Answer
Here's the short version before we dig in:
- Standard boots (3" diameter, about 2" tall): made for 20 oz to 40 oz cups with a base like the 40 oz Stanley Quencher, including the HydroJug Traveler 20–40 oz.
- 2.75" Shorty Waffle Boots™ (about 1.375" tall): a lower-profile boot tested on the Stanley Quencher 20–40 oz and other handled tumblers.
- 3.25" Shorty Boots: made for slimmer bottles like the Owala FreeSip and HydroJug Sport. These do not fit the Stanley Quencher.
- Bertha Boots: cut for 50 oz and 64 oz cups that are too wide for a standard boot.
Every boot is flexible silicone that protects the base from dents and scratches, quiets the clank on desks and counters, and holds snugly so it won't slide off when you lift your cup.
Standard Stanley Boot Size for 20 oz, 30 oz and 40 oz Cups
If you own a 40 oz Stanley Quencher, start with our standard size tumbler boots. They're sized for a 3" base, so they suit the most popular handled 40 oz cups and anything with a similar base, including the HydroJug Traveler 20–40 oz. With hundreds of designs (waffle, scallop, macrame, clear and more), this is where most of our customers shop.
Wondering about the Stanley 30 oz boot size? Standard boots are sized for 20 oz to 40 oz cups with a base like the 40 oz Quencher, and each product page lists its own fit notes, so give it a quick check before you order. A cozy holiday favorite right now is the Red Velvet Shimmer Waffle Boots™, a rich shimmery red that looks right at home on a red, cream or black cup.
2.75" Shorty Waffle Boots™: A Lower-Profile Stanley Boot
Love your cup's print and don't want to cover it? The 2.75" Shorty Waffle Boots™ sit lower on the cup, about 1.375" tall, so more of the design stays in view while the base still gets protection.
Our Black 2.75" Shorty Waffle Boots™ are tested to fit the Stanley Quencher 20–40 oz, Stanley IceFlow 20 and 30 oz, Simple Modern Trek and Pivot 30 and 40 oz, BrüMate Era 30 and 40 oz, and HydroJug Traveler 20–40 oz. Standard 3" boots also fit the HydroJug Traveler 20–40 oz, so the shorty is a great lower-profile pick if you switch between cup brands.
Does a Stanley Boot Fit Owala? Meet the 3.25" Shorty Boot
A boot sized for the Stanley Quencher isn't the right match for an Owala. Bottles like the Owala FreeSip have a different base, so we made the 3.25" Shorty Boots just for slimmer bottles.
The 3.25" Shorty is tested to fit the Owala FreeSip 24, 32 and 40 oz, HydroJug Sport 40 oz, BrüMate MultiShaker and Trio, Stanley Slim Bottle 34 oz, Stanley Camp Mug 8 and 24 oz, and the Stanley Aerolight IceFlow 36 oz. One important note: it does not fit the Stanley Quencher. Bright picks like Electric Orchid and classic White are easy wins for an Owala boot.
Do Stanley Boots Fit HydroJug?
It depends on which HydroJug you have. Standard 3" boots and 2.75" Shorty Waffle Boots™ both fit the HydroJug Traveler 20–40 oz. The 3.25" Shorty Boot does not fit the Traveler. The HydroJug Sport 40 oz is a bottle, so it takes the 3.25" Shorty Boot instead. When in doubt, measure the bottom of your cup and compare it to the size notes on the product page.
Boots for Big Cups: 50 oz and 64 oz Bertha Boots
Standard boots won't stretch over a 50 oz or 64 oz base, so bigger cups get the Bertha. The 50 oz Bertha Boot is sized for the Simple Modern 50 oz tumbler, and the 64 oz Bertha Boot is cut for the wide base of 64 oz tumblers, with options from Clear to Highland Cow and Floral. A full big cup is heavy, so the base takes the biggest hit every time you set it down. A boot is the best protection you can give it.
Finish Your Stanley Boot Look with a Charm and a Bow
Here's the good news: once your boot fits, the rest is easy. Our handle charms, straw toppers and bows work on cups of every size and brand. Start with the Large Bow Charm on your handle (it comes in Red, Pink and Purple), then keep it tonal. Pair the Red Bow Charm with the Red Velvet Shimmer boot and top it all off with a GOLDEN Glitter Tumbler Bow for a polished holiday look.
