Three cab sizes are available on the 2026 Chevy Silverado 1500, each built for a different balance of passenger room and overall truck length. The regular cab is a single-row, two-door layout with seating for up to three passengers, keeping the truck compact and paired exclusively with longer bed options for maximum cargo hauling. The double cab adds a second row and rear-hinged doors, seating up to five or six passengers depending on whether you opt for front bucket seats or a bench. The crew cab gives rear passengers full-size doors and the most second-row legroom in the lineup, making it the better pick for families or crews who spend extended time on the road. Both the double and crew cabs offer under-seat storage in the rear, and front bench seats include their own under-seat storage area.
The crew cab leads the lineup with 43.4 inches of rear legroom, compared to 35.24 inches in the double cab, while the regular cab is a single-row configuration with no rear passengers to accommodate. See the table below for a full breakdown of interior dimensions across all three cabs.
