When planning a kitchen or bathroom remodel, one of the most important elements to consider is cabinetry. At Reliable Design-Build-Remodel, we know that selecting the right cabinet sizes can make or break your space’s functionality and aesthetics. Whether you’re starting from scratch or simply updating your cabinetry, having a clear understanding of standard cabinet measurements helps ensure that your remodel runs smoothly and meets your expectations. Let’s walk through the most common questions homeowners ask about standard cabinet sizing.

What are standard cabinet sizes?
Standard cabinet sizes are established to make installation more efficient and ensure consistency across manufacturers. For base cabinets, the standard height is 34.5 inches without the countertop, and 36 inches with it. These are typically 24 inches deep, allowing for ample storage while maintaining ergonomic access. Wall cabinets generally come in heights of 12, 18, 24, 30, 36, and 42 inches, with a standard depth of 12 inches, although 15- to 24-inch depths are available for specialty uses. Tall pantry or utility cabinets usually stand at 84, 90, or 96 inches high and are 12 to 24 inches deep. These standard dimensions help create a balanced and functional kitchen layout.
What is the standard size of built-in cabinets?
Built-in cabinets—whether in a kitchen, living room, or bathroom—generally follow the same rules as stock cabinetry, though they may be custom-fitted to your specific space. In kitchens, built-ins typically align with the standard base and wall cabinet measurements for a cohesive look. However, in other parts of the home, such as living rooms or offices, built-ins can vary greatly. For example, built-in bookcases are often 12 to 15 inches deep with adjustable shelves, while built-in entertainment units may be 18 to 24 inches deep to accommodate electronics. At Reliable Design-Build-Remodel, we often tailor built-ins to your needs while referencing standard measurements for consistency and ease of use.
Are 42 inch cabinets too big?
It depends on your ceiling height and personal storage needs. In kitchens with 9-foot ceilings, 42-inch upper cabinets are not only appropriate but often preferred. They take advantage of the vertical space, allowing for more storage and a streamlined appearance. However, in homes with 8-foot ceilings, 42-inch cabinets can overwhelm the room or make it feel cramped, especially without proper lighting. They can also be difficult to access without a step stool. If you’re unsure whether 42-inch cabinets are the right choice for your space, our team at Reliable Design-Build-Remodel is happy to provide guidance and design solutions that balance height, function, and aesthetics.

Is it cheaper to buy cabinets or have them built?
Prefabricated or stock cabinets are generally more cost-effective than custom-built ones. They’re mass-produced in standard sizes, which reduces labor and material costs. Semi-custom cabinets offer more flexibility in design and sizing, and fall somewhere in the middle price-wise. Custom cabinets, on the other hand, are built to your exact specifications—ideal for unique layouts or specific design preferences—but they come at a premium. At Reliable Design-Build-Remodel, we help clients weigh the pros and cons based on budget, layout, and desired look. Sometimes a blend of stock and custom cabinetry offers the best of both worlds: affordability and personalization.
What is the most acceptable width of kitchen cabinet in a house?
The width of kitchen cabinets can vary depending on their purpose, but base cabinets typically come in increments of 3 inches, ranging from 12 inches to 48 inches wide. Wall cabinets follow a similar width pattern. The 30-inch and 36-inch widths are especially popular because they offer substantial storage without dominating wall space. For drawers, widths between 12 and 36 inches are common, depending on the contents—cutlery, utensils, pots and pans, etc. Our team at Reliable Design-Build-Remodel ensures that cabinet widths in your home are tailored to maximize functionality while maintaining a cohesive flow in the overall design.
What is the standard size of corner cabinets?
Corner cabinets present a unique challenge in kitchen design, but standard sizing does exist to simplify the process. For base corner cabinets, the most common style is the blind corner or the L-shaped cabinet. A standard blind corner base cabinet typically measures 36 inches to 42 inches wide on the exposed side and 24 inches deep. L-shaped corner cabinets also usually have 36-inch arms, forming a right angle. Wall corner cabinets follow similar patterns and typically measure 24 inches wide on each wall-facing side. Many homeowners opt for solutions like Lazy Susans or pull-out trays in corner cabinets to enhance accessibility. At Reliable Design-Build-Remodel, we make sure your corner cabinets aren’t just functional, but also a seamless part of your kitchen’s style.
