A 10-foot wall (120 inches) typically fits 3–5 base cabinets depending on widths. A common layout: two 36-inch cabinets + one 24-inch cabinet = 96 inches + filler strips to fill the remaining 24 inches. Or: four 30-inch cabinets = 120 inches exactly. Always plan for an appliance gap (typically 30 inches for a standard range and 30–36 inches for a refrigerator).

Base cabinets: 34.5 inches tall (plus a 1.5-inch countertop = 36 inches total). Upper wall cabinets: 30, 36, or 42 inches tall, mounted so the bottom is 54 inches from the floor (18 inches above the countertop). Tall pantry/utility cabinets: 84 or 96 inches tall, same depth as base cabinets (24 inches). Upper cabinets are typically 12 inches deep; base cabinets 24 inches deep.

Countertop runs on all base cabinet walls. Measure the linear feet of base cabinets on each wall and add 1–2 inches of overhang beyond the cabinet face. For an L-shaped kitchen with 10-foot and 8-foot walls, you need approximately 18–20 linear feet of countertop (including the corner piece). Stone countertops are sold by the square foot; laminate by linear foot.

Measure each wall where you want cabinets. Subtract appliance widths (refrigerator, range, dishwasher). Divide the remaining space by your planned cabinet widths. Work from corners outward, placing corner cabinets first. Use filler strips to fill odd gaps. Most kitchens use a mix of 24", 30", and 36"-wide base cabinets with 30"-wide upper cabinets being the most common.
