The KitchenAid 150 and KitchenAid 125 stand mixers differ primarily in their capacity, motor power, and price. The 150 is a larger, more powerful model with a 6.9-quart bowl and 325-watt motor designed for serious home bakers, while the 125 is a more compact, everyday mixer with a 4.5-quart bowl and 300-watt motor at a more accessible price point.
Here's everything you need to know to choose the right KitchenAid stand mixer for your baking projects and kitchen space.
KitchenAid 150 Stand Mixer
The KitchenAid 150 is a high-performance stand mixer built for serious home cooks and bakers who frequently work with large batches. Its powerful motor and extra-large capacity make it ideal for handling dense bread doughs, big batches of cookies, or small-scale commercial prep work, all while maintaining the brand's iconic style and durability.
- What it is: A professional-grade, high-capacity stand mixer for heavy-duty home and semi-pro use.
- Key features: Large 6.9-quart stainless steel bowl, a robust 325-watt motor, 10+ speed settings with precise controls, and the brand's signature planetary mixing action for thorough ingredient incorporation.
- Price: Around $500 to $600.
- Dimensions & Capacity: Accommodates very large batches with its 6.9-quart bowl, but requires significant countertop space due to its larger size and weight.
- Materials/Construction: Features a durable, all-metal construction that ensures stability and longevity, even under heavy load. Includes a flat beater, wire whip, and dough hook.
- Pros: Powerful motor handles tough doughs with ease. Extra-large bowl is perfect for batch baking and large families. Exceptionally stable and durable build quality. Compatible with all KitchenAid attachments for great versatility.
- Cons: Higher price point. Heavy and requires a dedicated spot on the counter. May be less efficient at mixing very small quantities.
The KitchenAid 150 is the right choice for frequent bakers, large families, or anyone who never wants to be limited by their mixer's power or capacity.

KitchenAid 125 Stand Mixer
The KitchenAid 125 is the brand's reliable workhorse for everyday home bakers. It delivers the same iconic performance and quality KitchenAid is known for but in a more compact and budget-friendly package. Its 4.5-quart bowl and 300-watt motor are perfectly suited for most standard baking tasks, from whipping cream to mixing cake batter and kneading bread dough for a single loaf.
- What it is: A versatile and compact stand mixer designed for everyday baking needs in a home kitchen.
- Key features: 4.5-quart stainless steel bowl, a capable 300-watt motor, 10-speed settings for various tasks, and planetary mixing action.
- Price: Typically priced between $350 and $450.
- Dimensions & Capacity: Its 4.5-quart bowl can handle standard recipes (e.g., up to 7 dozen cookies), and its smaller footprint makes it ideal for kitchens with limited counter space.
- Materials/Construction: Built with a sturdy die-cast metal body for durability and stability. Includes the essential flat beater, wire whip, and dough hook.
- Pros: More affordable price point. Smaller size is easier to store and fits well in most kitchens. Powerful enough for the vast majority of home baking tasks. Compatible with the same wide range of attachments as larger models.
- Cons: Smaller capacity limits the size of batches you can make. The motor might labor with very dense, large doughs compared to the 150.
The KitchenAid 125 fits perfectly for casual-to-regular bakers, smaller households, and anyone who wants premium performance without a professional-grade footprint.

KitchenAid 150 vs. KitchenAid 125 Comparison
Capacity & Size
The most obvious difference is size. The KitchenAid 150 comes with a generous 6.9-quart bowl, capable of mixing dough for up to 8 loaves of bread or 13 dozen cookies in a single go. This makes it a fantastic tool for holiday baking, large gatherings, or a small home bakery.
In contrast, the KitchenAid 125 has a 4.5-quart bowl, which is still quite spacious for everyday needs, handling recipes for about 7 dozen cookies or a standard loaf of bread. Its smaller physical footprint is a huge plus for those with compact kitchens or limited storage, as it's easier to move and doesn't dominate the counter.
Power & Performance
The KitchenAid 150 is equipped with a 325-watt motor, while the 125 has a 300-watt motor. While the 25-watt difference seems minor, the 150's motor is engineered to handle larger volumes and denser mixes - like stiff brioche or whole wheat doughs - for longer periods without straining. It provides consistent power when you need it most.
That said, the 300-watt motor in the KitchenAid 125 is more than capable for nearly all home baking tasks. It kneads bread, whips meringues, and mixes batters efficiently. You would only notice a difference if you repeatedly make very large or incredibly dense doughs.
Materials & Construction
Both models stay true to KitchenAid's reputation for quality. They feature robust, die-cast all-metal bodies that provide stability and minimize vibrations during use. This heavy construction ensures they won't "walk" across your counter, even when kneading heavy dough. The bowls are stainless steel, and the internal gears are metal, promising years of reliable use. The main difference in feel comes from sheer scale - the 150 is noticeably heavier and more substantial, giving it a professional presence, while the 125 feels just as sturdy but more manageable.
Price & Value
The KitchenAid 150 typically costs $150–$200 more than the 125, placing it in a premium category. The value is clear for those who will actually use its enhanced capacity and power. For prolific bakers, it's a sound investment that saves time and supports ambitious culinary projects.
The KitchenAid 125 offers exceptional value for the average home baker. You get the revered KitchenAid performance, durability, and access to the ecosystem of attachments for a lower initial cost. For most people, it's all the mixer they will ever need.
Which One Should You Choose?
Both mixers are excellent products, but they are built for different types of users and kitchens.
Choose the KitchenAid 150 if:
- You regularly bake in large batches for a big family, parties, or bake sales.
- You frequently make dense bread doughs and need a motor that won't strain.
- You have ample counter space and don't plan on moving the mixer often.
- You see your mixer as a long-term investment for serious-to-professional baking.
Choose the KitchenAid 125 if:
- You bake for a smaller household (1-4 people) on a weekly basis.
- Your kitchen is compact and you need a mixer with a smaller footprint.
- You want the classic KitchenAid quality and performance at a more accessible price.
- Your baking repertoire includes cakes, cookies, and standard bread recipes.
Frequently Asked Questions
What is the main difference between the KitchenAid 150 and 125?
The primary difference is capacity and power. The 150 has a larger 6.9-quart bowl and a more powerful 325-watt motor, making it ideal for large, heavy-duty batches. The 125 has a smaller 4.5-quart bowl and a 300-watt motor, designed for standard everyday home baking.
Is the KitchenAid 150 worth the extra money?
Yes, if you frequently bake in large quantities or work with very dense doughs. For serious bakers who often find their current mixer too small, the power and capacity of the 150 are well worth the investment. For casual bakers, the 125 provides more than enough performance for a lower price.
Can the KitchenAid 125 handle bread dough?
Absolutely. The KitchenAid 125 is fully capable of kneading bread dough for standard home recipes, typically for one or two loaves at a time. It may struggle only with exceptionally large or very stiff, low-hydration doughs where the KitchenAid 150 would excel.
Do the same attachments work on both the 150 and 125 models?
Yes, both models use the same power hub for attachments. This means the pasta maker, meat grinder, ice cream maker, and various other official KitchenAid attachments are compatible with both mixers, making them equally versatile.
Can I mix small batches in the KitchenAid 150?
You can, but it may be less efficient. The large size of the 6.9-quart bowl and the reach of the attachments are optimized for bigger volumes. Mixing a very small amount, like a single egg white, might result in the ingredients being pushed to the side of the bowl rather than being properly incorporated.
How much bigger is the KitchenAid 150?
Dimensionally, the 150 is taller, wider, and significantly heavier than the 125. It requires a dedicated spot on the counter, whereas the 125 is more easily stored in a pantry or cabinet if counter space is tight.
Which KitchenAid is better for a beginner?
The KitchenAid 125 is generally the better choice for a beginner. It offers the full KitchenAid experience - power, reliability, and versatility - at a more approachable price and manageable size, without overwhelming a new baker with excess capacity.
Do both mixers come in a variety of colors?
Yes, both the 150 and 125 are typically available in a range of classic KitchenAid colors to match any kitchen decor, although specific color availability can vary by retailer and model line.
