Choosing the right tumbler size can boost your hydration and simplify your routine. But how many ounces do tumblers actually hold?
Tumblers typically range from 20 to 64 ounces1, with 30 oz and 64 oz being the most common sizes offered by brands like RTIC and Yeti.
Let’s explore popular sizes, how they fit into daily life, and how to choose the one that suits your needs.
What Are the Most Common Tumbler Sizes Available?
Tumbler sizes aren’t one-size-fits-all. I’ve used everything from 20 oz to 64 oz.
The most popular sizes are 20 oz, 30 oz, and 64 oz, with 30 oz being the most common everyday option.
Size Overview
| Size | Typical Use Case | Portability |
|---|---|---|
| 20 oz | Coffee, short outings | Very portable |
| 30 oz | Daily hydration, work, commuting | Fits car holders |
| 64 oz | Long trips, hiking, sharing | Bulky, less portable |
Each size fits different hydration habits and activities.
How Does Tumbler Capacity Affect Your Daily Hydration Needs?
Hydration is personal. I choose based on my day.
A 30 oz tumbler2 covers most daily needs with fewer refills; a 64 oz size supports extended outdoor activities.
If you drink coffee or water throughout the day, a 30 oz tumbler is a great balance. For longer trips or events, the 64 oz keeps you hydrated longer.
What Size Tumblers Does RTIC Offer?
RTIC focuses on utility and capacity.
RTIC mainly offers 30 oz and 64 oz tumblers, both featuring double-wall insulation3 and spill-resistant designs.
RTIC Tumbler Specs
| Model | Capacity | Dimensions (inches) | Key Features |
|---|---|---|---|
| RTIC 30 oz Tumbler | 30 oz | 4" W x 4.5" D x 8" H | Ceramic-lined, spill-proof, car-friendly |
| RTIC 64 oz Road Trip | 64 oz | Larger (not cup holder-sized) | All-day cold retention, large capacity |
Both are made from 18/8 stainless steel and keep beverages hot or cold for hours.
How Do Different Brands Compare in Tumbler Capacities?
RTIC isn’t alone. I’ve compared other top brands too.
RTIC, Yeti, and Hydro Flask all offer tumblers in 20 oz, 30 oz, 40 oz, and 64 oz options4.
Brand Comparison
| Brand | Available Sizes (oz) | Notes |
|---|---|---|
| RTIC | 30, 64 | Affordable, rugged design |
| Yeti | 20, 30, 46, 64 | Premium pricing, similar build |
| Hydro Flask | 20, 30, 40, 64 | Stylish, outdoor-focused |
All brands use double-wall vacuum insulation and durable stainless steel.
How to Choose the Right Tumbler Size for Your Lifestyle
Choosing a tumbler is about matching it to your habits.
Pick your size based on your activity, liquid needs5, and how often you want to refill.
Selection Tips
- 20 oz: Best for coffee, short drives
- 30 oz: Ideal for work, gym, or daily hydration
- 64 oz: Best for long hikes, events, or all-day use
Smaller sizes are easier to carry; larger ones reduce refill frequency.
What Are the Dimensions and Features of Popular Tumblers?
Size isn’t everything. I also look at features.
Popular tumblers like RTIC’s 30 oz model offer spill resistance, car cup compatibility, and long-lasting insulation6.
Key Features to Look For
- Spill-proof lids
- Car cup holder fit
- Ceramic or BPA-free linings
- Dishwasher-safe components
- Double-wall vacuum insulation
These make daily use easier and cleaner.
Conclusion
Tumblers range from 20 to 64 oz. Choose based on activity, refills needed, and portability to find your perfect fit.
