20 oz vs 30 oz YETI® Tumbler: Which Size Should You Choose?
The 20 oz and 30 oz YETI® tumblers are two popular choices for personalised everyday drinkware.
The 20 oz tumbler holds approximately 591 mL, while the 30 oz version holds approximately 887 mL. Both are designed to fit most cupholders and include a splash-resistant MagSlider™ lid. The lids help contain splashes but are not completely leakproof.
The best size depends on how much you normally drink, where you will use it and whether you prefer a lighter or larger cup.
Browse both sizes in our personalised YETI® tumbler collection.

Why Choose the 20 oz Tumbler?
The 20 oz tumbler is the better all-round option for many customers.
It offers enough capacity for:
- Morning coffee
- Iced coffee
- Water
- Soft drinks
- Tea
- Everyday cold beverages
Its smaller size makes it easier to carry between home, work and the car.
It is a strong choice for:
- Office workers
- Teachers
- Commuters
- Everyday coffee drinkers
- Client gifts
- Employee gifts
- Customers who prefer a more compact tumbler
A name, monogram or business logo can be prominently engraved without the product feeling oversized.
Why Choose the 30 oz Tumbler?
The 30 oz tumbler is ideal for customers who want more capacity and fewer refills.
It is particularly useful for:
- Large iced coffees
- Longer drives
- Full workdays
- Outdoor events
- Larger cold drinks
- People who regularly finish a 20 oz drink too quickly
The taller body also provides more room for longer designs and vertically arranged artwork.
Consider a 30 oz tumbler when you want to include:
- A large logo
- A detailed illustration
- A longer name
- A logo and accompanying text
- A prominent double-sided design
Which Is Better for Coffee?
The 20 oz tumbler will suit most standard coffee orders and everyday hot drinks.
Choose the 30 oz version when:
- You make a large coffee at home.
- You drink coffee slowly throughout the morning.
- You regularly purchase large iced coffees.
- You want extra capacity for milk and ice.
- You prefer fewer refills.
Remember that the MagSlider™ lid is not completely leakproof. Keep the tumbler upright when carrying it.
For a twist-on, leak-resistant lid and handle, consider a product from our YETI® coffee mugs collection.
Which Is Better for Water?
The 30 oz tumbler provides more capacity, but it may not be as convenient to carry as a closable bottle.
For water at a desk, in the car or around the house, either size can work well.
For worksites, sport, walking or outdoor activities, a personalised YETI® drink bottle may be more practical.
Which Fits Better in a Car?
Both models are designed to fit most cupholders, but vehicle cupholders are not universal.
Before ordering:
- Measure the cupholder opening.
- Check available height beneath the dashboard or console.
- Consider whether the taller cup may interfere with controls.
- Check whether you need to remove it while changing gears.
- Consider the weight when the cup is completely full.
The 20 oz model is generally the safer choice for smaller vehicles or crowded centre consoles.
Which Is Better for Engraving?
Both sizes provide excellent engraving opportunities.
Choose the 20 oz for:
- Names
- Initials
- Monograms
- Simple logos
- Short messages
- Small illustrations
Choose the 30 oz for:
- Larger artwork
- Detailed logos
- Longer names
- Vertical designs
- Multiple design elements
- More prominent personalisation
Single-sided and double-sided options may be available depending on the selected product.
Which Makes the Better Gift?
The 20 oz tumbler is the safer general gift because its size suits a wide range of users.
The 30 oz tumbler may be better for someone who:
- Loves large iced drinks
- Travels long distances
- Works long hours
- Spends time outdoors
- Already carries large drinkware
- Prefers fewer refills
Add a name, photograph, logo, message or artwork to make either size personal.
