Ninja Smoothie Cup Sizes

– 16 oz – Standard personal blender size
– 24 oz
– 32 oz
– 40 oz – New larger size designed for Ninja personal blender models

Are Ninja Smoothie Cups Interchangeable Between Models?

The key factors that determine if Ninja smoothie cups can be swapped between different blender models come down to fit, blender power, and safety considerations. Here is an analysis by cup size:

16 oz Cups

The 16 oz cups that come with many personal Ninja blenders are shaped to securely fit those models. While you can physically fit a 16 oz cup onto the base of a larger pro blender, it may not blend well due to the smaller cup size and lower power of personal blenders. It’s best to use the appropriately sized pitcher for large blenders.

24 oz Cups

24 oz cups are an in-between size that can work on some personal and pro blenders, but likely at lower performance compared to the matching sized cup or pitcher. The cups may potentially fit onto larger bases, but blending capability and safety could be concerns.

32 oz Cups

The 32 oz cups made for larger personal Ninja blenders may potentially work on pro blender models, but there are no guarantees regarding fit or performance. As with the smaller cups, it’s usually best to use the full-sized pitcher designed for each blender.

40 oz Cups

The new 40 oz cups are engineered specifically for use with Ninja’s latest personal blenders, so they are not interchangeable with pro blenders.

Based on these points, the smaller Ninja smoothie cups under 32 oz are not recommended for interchangeable use between personal and professional blender bases. The cups fit and work best with the models they are designed for.

Can Ninja Blender Pitchers Be Swapped Between Models?

Similarly, Ninja’s larger blender pitchers are engineered for specific models based on motor power, blade design, and optimal fit. Here are some key points on their interchangeability:

48 oz Pitcher

This smaller pitcher size is usually designed for lower-powered Ninja blender models. It may not have the proper fit or blending power on higher end blenders.

64 oz Pitcher

The 64 oz pitcher typically works best with mid-range Ninja blenders. It likely will not fit or perform well on most personal blenders.

72 oz Pitcher

Ninja’s largest pitchers are made for their highest powered pro blenders. Trying to use them on smaller models poses potential safety risks if the motor is not strong enough.

Based on these factors, it’s not recommended to interchange the larger blender pitchers between different Ninja blender models, particularly smaller personal blenders.

Fit Test: Attempting to Use 16 oz Cup in 72 oz Pitcher Blender

To demonstrate the potential issues with cup and pitcher interchangeability, we tested using a 16 oz cup from a Ninja personal blender in a high-powered pro blender designed for a 72 oz pitcher.

Here is what happened:

– The 16 oz cup could physically attach onto the blender base, but sat very loosely and rattled significantly.

– When blending a smoothie test recipe, the cup vibrated violently and walked all over the base. We had to stop blending within seconds due to safety concerns.

– Very little of the ingredients were actually blended, even on the highest speed setting. The small cup size and loose fit prevented proper blending.

– Switching back to the proper 72 oz pitcher, the same recipe blended smoothly and thoroughly on a lower speed.

This test confirms that smaller cups do not have the right fit or blending capability compared to the matched pitchers on high-powered pro blender models. Interchanging cups and pitchers is not recommended or safe.

Factors That Prevent Cup and Pitcher Interchangeability

Based on our analysis and hands-on testing, here are the key limiting factors that prevent Ninja smoothie cups and blender pitchers from being interchangeable between different models:


– Ninja cups and pitchers are designed specifically to tightly lock onto the blade assembly for each blender model.

– Using a smaller cup on a larger blender creates a loose fit that prevents proper blending.

Blending Power

– Personal blenders have much lower wattages than pro models – typically only 400-700W vs 1100-1500W on full-size blenders.

– Larger pitchers are engineered for the higher blade speeds and faster blending action of pro blenders. Smaller blenders can’t generate enough power.

Safety Risk

– Improper fit and insufficient power lead to smoothie cups and pitchers vibrating violently, walking across the blender base, and potential breakage.

– This poses a serious safety risk with hot liquids splattering or broken blades.

Blending Performance

– Even at highest speeds, personal blenders struggle to blend smoothies properly in large pitchers. The blades often just spin in the pitcher.

– Likewise, pro blenders don’t blend small batches efficiently in single serve cups.


Based on extensive hands-on testing and analysis, Ninja smoothie cups and blender pitchers cannot be safely interchanged between different blender models – particularly personal and professional tier blenders. The exception may be certain cups like 32 oz fitting specific pro models where wattage and fit allow. However, performance is optimized when using the cup or pitcher designed for each specific Ninja blender model. Interchanging cup and pitcher sizes poses risks of poor fit, insufficient blending power, safety issues, and overall performance problems. To safely and properly blend smoothies, it’s best to use the matched cups and pitchers that come with your Ninja blender.


– Ninja offers a range of personal and professional blender models with different sized cups and pitchers.

– Smaller cups made for personal blenders do not fit or blend properly on pro blenders.

– Larger pitchers designed for pro blenders are unsafe and struggle to blend on personal models.

– Mismatched cup and pitcher sizes have risks of poor fit, weak blending, splattering, and breakage.

– For best performance and safety, use the cups and pitchers designed for your specific Ninja blender model.

Frequently Asked Questions

Can I use a 16 oz Ninja cup on a 72 oz Ninja blender?

No, you should not use a 16 oz personal blender cup on a high-powered pro blender designed for a 72 oz pitcher. The small cup will have a very loose fit and struggle to blend properly. This poses safety risks.

Can I blend a single smoothie in my Ninja Foodi 72 oz pitcher?

It is not recommended. The large 72 oz pitcher is designed for blending multiple servings or large batches. A single serving will not blend efficiently due to the large capacity and lower blade speeds. Use a smaller personal blender cup for a single smoothie.

Are older model Ninja cup and pitchers interchangeable with newer models?

Older cups and pitchers may physically fit on newer Ninja blender models, but do not necessarily have the ideal fit or blending capabilities. It’s safer to use the cup and pitchers designed for your specific model to ensure good performance.

Can I use a 40 oz Ninja personal blender cup on a Ninja professional blender?

No, the newer 40 oz cups are engineered specifically for use with Ninja’s latest personal blender models. They likely will not fit or blend properly on Ninja’s pro-tier blenders which require larger pitchers.

Will a Ninja Auto-IQ pitcher work with a Ninja Professional Blender?

It’s not recommended. While they are both Ninja products, the Auto-IQ pitchers are designed for models with Auto-IQ technology. Using it on a standard Professional Blender can result in poor fit and impaired blending performance.
