Common Smoothie Cup Sizes Explained
Smoothie cups typically range from small sample sizes to large meal-replacement portions. Here’s a breakdown of the most popular options on the market.
8 oz (240 ml) – Small or Kids’ Size
This is ideal for children’s menus, tasting promotions, or low-calorie smoothies. These small smoothie cups are affordable, easy to store, and great for sampling programs.
12 oz (360 ml) – Regular
The 12 oz smoothie cup is a standard size used across many independent smoothie shops and national chains. It offers a balanced portion for regular fruit smoothies or protein blends.
- Commonly used for base menu smoothies
- Excellent for controlled calorie servings

If you're starting with a small menu, the 12 oz option is a safe, cost-effective default.
16 oz (470 ml) – Large
The 16 oz smoothie cup is arguably the most popular size in the smoothie industry. It allows room for more ingredients, additional toppings, or nutrient-dense blends like green smoothies and protein shakes.
- Best for regular or high-volume customers
- Ideal for cold smoothies with granola, fruit bits, or chia
- Used widely in Smoothie King cup sizes as the “middle” or “regular” option in their three-tiered size system

Choosing the Right Smoothie Cup Size for Your Menu
Your smoothie cup size strategy should be based on what you sell, how your customers behave, and what kind of pricing model you want to use. Here’s how to approach it:
- Basic smoothies or kids' options: 8 oz or 12 oz smoothie cups are perfect for lower-cost menu items and calorie-conscious offerings.
- Standard fruity or green smoothies: 16 oz smoothie cups are the industry sweet spot big enough to satisfy, small enough to keep margins healthy.
- Protein shakes or detox blends: 20 oz cups and up work well for customers looking for meal replacements or pre/post-workout fuel.
- Custom tiered sizes: You can create small-medium-large options to mirror big brands like Smoothie King or Planet Smoothie, helping customers intuitively navigate your menu.
If you’re launching a new smoothie bar, offering two to three cup sizes for example, 12 oz, 16 oz, and 20 oz can give you the flexibility to upsell without overwhelming operations.
How Cup Size Affects Packaging Material Choice
The size of your smoothie cups can directly affect which packaging materials are most suitable:
- Small cups (8–12 oz): These typically work well with thinner PET or PLA materials, and flat lids. Ideal for smoothies without toppings.
- Medium to large cups (16–20 oz): Require stronger cup walls (e.g., thicker PET or PP), dome lids to accommodate toppings or whipped cream, and wider straws.
- Extra-large cups (22–32 oz): Best paired with reinforced bottoms, tight-sealing lids, and anti-leak materials especially important for delivery or takeaway.
If you're using custom printed smoothie cups, larger sizes also offer more surface area for logo placement, slogans, or QR codes.
Custom Printing and Branding per Cup Size
Branded cups are one of the most powerful marketing tools in your store. Customers walk around with them, take photos, and post them online turning every drink into free advertising.
Here’s how cup size supports your branding goals:
- 12 oz smoothie cups: Great for compact logos, color branding, and icons
- 16 oz smoothie cups: The most versatile for full-color wrap designs, perfect for mid-size exposure
- 20+ oz cups: Maximize visual impact with taglines, loyalty offers, or event promotions
Pairing cup sizes with smart label design is a cost-effective way to grow brand visibility without spending extra on advertising.
Conclusion
Choosing the right smoothie cup sizes isn’t just about holding your product it’s about optimizing portion control, cost efficiency, and customer satisfaction.
