how deep are base cabinets in kitchen

Based on the search results, here's a detailed overview of standard and custom depths for kitchen base cabinets:

📏 ​Standard Base Cabinet Depth​

​Standard Depth:

Most factory-made stock base cabinets have a uniform depth of ​24 inches​ (measured from the front edge to the wall) .

Note: Countertops typically extend 1–2 inches beyond the cabinet front, making the total countertop depth ​25–26 inches.

🔧 ​Custom Depth Options​

While 24 inches is the industry standard, custom or specialty cabinets may vary:

​Shallow Cabinets (18 inches)​:
Ideal for small kitchens or tight spaces where standard cabinets would obstruct movement .

​Deep Cabinets (30 inches)​:
Used in large kitchens for extra storage, but may make accessing items at the back difficult .

​Custom Widths:
Base cabinets come in widths ranging from ​12 to 48 inches​ (e.g., 12", 15", 18", 21", 24", 30", 36") to fit various layouts.

⚠️ ​Key Considerations​

​Toe Kick: A recessed space at the bottom of base cabinets, standardized at ​3 inches deep, allows comfortable standing near countertops.

​Appliance Alignment: Ensure appliances (e.g., refrigerators, ovens) align with cabinet depths to avoid protrusions.

​Building Codes: Some jurisdictions restrict cabinet depths for safety or accessibility reasons.

💎 ​Summary Table​

For optimal functionality, pair 24-inch base cabinets with ​12-inch-deep wall cabinets​ and maintain ​18 inches of clearance​ between countertops and upper cabinets.
