Largest Electric Cooktop: Sizes, Brands, and What Fits (2026)

The largest widely available electric cooktops are 36 inches wide — fitting a 34.5-inch countertop cutout and providing five or six cooking zones with room for large stockpots, griddles, and simultaneous multi-dish cooking. Beyond 36 inches, specialty models at 45 and 48 inches exist from brands like Viking and Thermador, but they are rare, expensive, and require custom cabinetry. This guide covers the full size spectrum of electric cooktops (30, 36, 45, and 48 inches), how radiant and induction technologies compare at larger formats, the bridge-element feature that makes large cooktops especially versatile, installation and electrical requirements, pricing, and how to decide whether you actually need the largest size or whether a well-configured 30-inch model serves you better.
