GMC Canyon data analysis
How GMC Canyon bed length varies
Across 20 configurations recorded for the 2015 through 2026 GMC Canyon, bed length runs from 61.7 inches to 74 inches. The strongest figure belongs to the 2015 GMC Canyon (6-ft 2-in Long Bed) at 74 inches, and the weakest to the 2026 car (5-ft 2-in Bed) at 61.7 inches — a spread of 20%. A gap that wide means the model year and configuration you buy matter more than the nameplate does: quoting a single number for the GMC Canyon would be misleading.
What changed for 2026
Average bed length for the 2026 GMC Canyon is 61.7 inches, against 61.7 inches for the 2025 car — it held flat. A carry-over year like this usually means no powertrain or structural change, so an older example is the cheaper way into the same specification.
How to read this GMC Canyon data
This page lists every 2015 through 2026 GMC Canyon record we hold for this measurement — 20 rows in total, one per configuration and model year rather than a single headline figure. Figures are published as the source agency records them: we do not round, average or interpolate missing years, and a year that is absent from the table is a year with no published measurement rather than a zero. Where a manufacturer offered several drivetrains or body styles in the same year, each appears on its own row, because those variants rarely share the same numbers.
Configurations behind these GMC Canyon numbers
The 2015 through 2026 GMC Canyon entries here cover the variants 5-ft 2-in Bed, 5-ft 2-in Short Bed and 6-ft 2-in Long Bed. 2022 is the busiest model year in the record with 2 separate measured configurations, which is why a single quoted bed length figure for that year is rarely the one that matches the car in front of you. Match the row to the exact drivetrain, body style and engine on the window sticker or VIN before relying on the number, and use the comparison links below to see how those same configurations line up against rival models.
Where these GMC Canyon figures come from
Every value on this page is loaded from federal open data — EPA fuel economy submissions, NHTSA vehicle and crash-test records, and manufacturer specification filings — rather than dealer listings or copied editorial content. The GMC Canyon record refreshes as the agencies publish, which typically means new model-year rows appear in the autumn and crash-test results follow through the model year as vehicles are tested. Because certification data is filed per configuration, treat any single headline number for this vehicle with caution: the figure that applies to a specific car depends on its engine, drivetrain, body style and model year, all of which are listed separately above. If a number here disagrees with a brochure, the brochure is usually quoting the best available configuration rather than the one being sold.
Frequently Asked Questions About Canyon Bed Size
How long is the GMC Canyon bed?
The GMC Canyon bed measures 74 inches (6.2 ft) at the floor in the 6-ft 2-in Long Bed. Shorter bed configurations are listed year by year in the table above.
Will a 4x8 sheet of plywood fit in a GMC Canyon?
The GMC Canyon measures 44.4 inches between the wheel wells, so a 48-inch sheet will not sit flat between them — it has to rest on top of the wheel wells or ride at an angle. With the tailgate down and the load properly flagged, an 8-foot sheet will overhang on any short bed.
How much cargo volume does the GMC Canyon bed have?
Cargo volume is about 49.9 cubic feet with a 20.9-inch bed depth. Volume is measured to the top of the bed rails, so a level load will be less.
