How many cubic feet is a Suburban?
The Suburban's cargo footprint varies by how many rows you fold or leave in place. In short, you’re looking at about 41.5 cubic feet behind the third row, up to roughly 93.8 cubic feet behind the second row, and as much as about 144.7 cubic feet with both the second and third rows folded flat.
In this article, we break down the cargo figures for the current-generation Suburban, explain how seating configuration affects space, and note what to expect across model years and trims.
Cargo space by seating configuration
The following figures reflect Chevrolet's published specifications for the current-generation Suburban (model years 2021 and newer). They show how space changes depending on how many rows are in use.
- Behind the third row: 41.5 cubic feet (approximately 1.18 cubic meters).
- Behind the second row (with the third row folded): 93.8 cubic feet (approximately 2.66 cubic meters).
- Behind the first row (with both the second and third rows folded): 144.7 cubic feet (approximately 4.10 cubic meters).
Note that real-world cargo can vary with optional equipment, floor mats, and whether the second or third rows are configured differently (e.g., captain's chairs vs. a bench). Always verify the exact specification for a given vehicle and trim.
Notes on variation
These numbers are intended to represent typical Suburban cargo capacity. Model-year updates can tweak interior dimensions slightly, and vehicle setups such as a dual-occupant seating arrangement or removable floor panels can affect the usable space. If you need precise figures for a specific build, consult the dealer window sticker or Chevrolet's official specs for that model year.
Summary
The Chevrolet Suburban offers a broad cargo range: 41.5 cu ft behind the third row, 93.8 cu ft behind the second row, and up to 144.7 cu ft with both rear rows folded. These figures provide a practical guide for families and buyers who need substantial hauling capacity, with space scaling based on how many rows are in use.
