GMC Canyon Bed Size Chart by Year 2004-2026 (All Models)
The GMC Canyon bed size chart varies by model year and cab configuration. The 2023–2026 Canyon has a single 61.7-inch short bed, while 2015–2022 models offered 61.7-inch short and 74.0-inch long beds.
First-generation trucks used shorter nominal box dimensions, and GMC’s 2012 brochure lists a small measurement difference from earlier years.
Use the charts below to find the bed length, interior width, wheelhouse clearance, and cab combination for your Canyon. If you’re buying a tonneau cover, bed liner, or storage system, confirm the exact model-year fitment before ordering.

GMC Canyon Bed Size Chart by Model Year
The following measurements are inside cargo-box lengths at the floor, with the tailgate closed. They are not the truck’s overall exterior length or the distance along the top bed rails.
| GMC Canyon Model Years | Cab Configuration | Factory Bed | Length at Floor |
|---|---|---|---|
| 2004–2011 | Crew Cab | Short box | 61.1 in. |
| 2004–2012 | Regular Cab | Long box | 72.8 in. |
| 2004–2012 | Extended Cab | Long box | 72.8 in. |
| 2012 | Crew Cab | Short box | 61.4 in. |
| 2013–2014 | Not sold in the U.S. | None | N/A |
| 2015–2022 | Crew Cab | Short box | 61.7 in. |
| 2015–2022 | Extended Cab | Long box | 74.0 in. |
| 2015–2022 | Crew Cab | Long box | 74.0 in. |
| 2023–2026 | Crew Cab | Short box only | 61.7 in. |
How to read the chart: A 61.7-inch bed is approximately 5 feet 2 inches long. A 74.0-inch box is approximately 6 feet 2 inches. These rounded names are useful for identifying a bed category, but they are not a substitute for a vehicle-specific accessory fitment listing.
Historical measurement note: GMC’s 2011 documentation specifies a 61.1-inch Crew Cab box, while its 2012 brochure specifies 61.4 inches. Those figures are reported as published; the documents alone do not establish that the physical box design changed. When dealing with a 2012 truck, use its model-specific parts listing and measure the actual bed.
The Canyon was absent from the U.S. new-truck lineup for model years 2013 and 2014. The second-generation truck arrived for 2015, followed by another redesign for 2023.
How 2004 to 2012 GMC Canyon Bed Sizes Differ
The first-generation GMC Canyon paired the Regular Cab and Extended Cab with a long box. Crew Cab trucks used a shorter box, giving buyers more passenger space without extending the truck to a full-size pickup’s dimensions.
Crew Cab Short Box
For the early first-generation Crew Cab, the published cargo-floor length is 61.1 inches. Archived GMC factory specifications from 2006 also list a 57.2-inch interior floor width, 42.6 inches between the wheelhousings, and 18.6 inches of inside box height.
The same 61.1-inch short-box length appears in GMC’s 2011 documentation. For 2012, however, the GMC Canyon brochure lists 61.4 inches for both 2WD and 4WD Crew Cab models. The brochure still lists 57.2 inches of inside width at the floor.
Regular and Extended Cab Long Box
The long bed measures 72.8 inches at the floor, or about 6 feet 1 inch. GMC lists that length for both Regular Cab and Extended Cab configurations, including 2012 models.
The first-generation long box has a published interior width of 57.2 inches and a width of 42.6 inches between the wheelhousings. Those measurements are useful when comparing toolboxes or wide cargo, but hardware fitment still depends on the truck and accessory.
The next Canyon generation changed the long-bed length and expanded Crew Cab choices.
Which Beds Fit 2015 to 2022 GMC Canyon Cabs
The second-generation Canyon offered two cargo-box lengths. You could get a 61.7-inch short bed with a Crew Cab or a 74.0-inch long bed with an Extended Cab or a properly configured Crew Cab.
Crew Cab Short Bed
The Crew Cab short box measures 61.7 inches at the floor and provides 41.3 cubic feet of published cargo volume. It works for owners who want a full rear-seat cabin while keeping the truck’s overall length relatively compact.
The inside width between the wheelhousings is 44.4 inches. The wider floor dimension is approximately 57.8 inches. That narrower wheelhouse opening matters if you regularly carry broad, rigid items that need to sit flat on the bed floor.
Extended and Crew Cab Long Bed
The 74.0-inch long box provides roughly 12.3 inches more cargo-floor length than the short box. Published cargo volume rises to 49.9 cubic feet, with the same 44.4-inch wheelhouse clearance.
The official 2021 GMC Canyon brochure confirms all three arrangements: Extended Cab long bed, Crew Cab short bed, and Crew Cab long bed. Exact trim and drivetrain availability can differ by model year.
A long-box Crew Cab Canyon from this generation is not interchangeable with a short-box Crew Cab when selecting bed accessories.
2023 to 2026 GMC Canyon Bed Dimensions Explained
GMC simplified the Canyon lineup for the 2023 redesign. Every 2023–2026 U.S.-market Canyon uses a Crew Cab with a 61.7-inch short bed. The previous 74.0-inch long bed and Extended Cab body style are no longer offered on these model years.
The modern cargo box measures 58.1 inches wide at the floor, with 45.5 inches between the wheelhousings. Published cargo volume is 41.9 cubic feet. GMC’s detailed Canyon dimensions document the exact figures, which are also consistent with 2026 specification listings.
What Changed After the 2023 Redesign
The short-bed length stayed at 61.7 inches, but the cargo area’s shape changed. Compared with the 2022 Crew Cab short box, the redesigned bed is approximately 0.3 inch wider at the floor and 1.1 inches wider between the wheelhousings.
That distinction matters for accessories. A product designed to clamp to the bed rails or follow the inner box contours may not fit both generations, even though the advertised bed lengths match.
The Canyon and Chevrolet Colorado share a platform, but appearance, trim features, and some equipment choices differ. Our GMC Canyon vs Chevy Colorado comparison explains the broader differences without assuming every bed accessory is interchangeable.
How Wide and Deep Is the GMC Canyon Bed
Bed length tells only part of the cargo story. The width available between the wheelhousings is more restrictive than the wall-to-wall floor width when you’re loading wide boxes, equipment, or sheet goods.
| Cargo-Box Measurement | 2006 First Generation | 2022 Second Generation | 2023–2026 Third Generation |
|---|---|---|---|
| Short-bed floor length | 61.1 in. | 61.7 in. | 61.7 in. |
| Inside width at floor | 57.2 in. | 57.8 in. | 58.1 in. |
| Width between wheelhousings | 42.6 in. | 44.4 in. | 45.5 in. |
| Short-bed cargo volume | 37.0 cu. ft. | 41.3 cu. ft. | 41.9 cu. ft. |
The first-generation column represents documented 2006 specifications, not a claim that every dimension remained unchanged across 2004–2012. The 2023–2026 column reflects the current-generation published specification.
Bed Width at the Floor
The modern Canyon has a 58.1-inch floor width, compared with about 57.8 inches on the previous generation. This is the broad inside-bed measurement, not a guarantee that an item of the same width can pass through every point of the tailgate opening.
Width Between Wheelhousings
The third-generation opening measures 45.5 inches, while second-generation trucks have 44.4 inches. Both are narrower than a standard 48-inch-wide sheet laid flat between the wheelhousings. Such sheets need a suitable elevated support arrangement rather than being forced onto the floor between the wheel wells.
For comparison with the closely related Chevrolet pickup, see our Chevy Colorado bed size chart by year. Check Canyon-specific figures rather than copying Colorado measurements across models.
Bed Depth and Cargo Volume
The archived 2006 Canyon specification gives an 18.6-inch inside box height. For later Canyon generations, the manufacturer sources reviewed do not consistently publish a directly comparable bed-floor-to-rail height, so a single unverified depth figure would be misleading.
If your load depends on vertical clearance under a tonneau cover, measure the installed cover’s underside clearance and the actual bed floor. Box volume does not equal the dimensions of the largest object you can load.
Which GMC Canyon Cab Styles Have Long Beds
Bed availability depends on both the model year and cab type. A Crew Cab alone is not enough to identify bed length on 2015–2022 trucks.
First Generation 2004 to 2012
Regular Cab and Extended Cab models used the 72.8-inch long box. Crew Cab models used the approximately 61-inch short box, with the 2012 brochure giving the slightly different 61.4-inch figure.
Second Generation 2015 to 2022
Extended Cab models used the 74.0-inch bed. Crew Cab buyers could select a 61.7-inch short box or, on available configurations, a 74.0-inch long box.
Third Generation 2023 to 2026
The current-generation Canyon is Crew Cab-only with a 61.7-inch short box. There is no factory 6-foot long-bed option on these model years.
For an unknown used truck, confirm its year and cab style, then check the box directly rather than relying on a sales description.
How to Measure a GMC Canyon Truck Bed
A tape measurement is the most reliable final check before ordering an accessory. Use the specific measurement method required by the accessory manufacturer, because tonneau covers, liners, and racks do not always use the same reference points.
- Close the tailgate. Park on level ground, remove loose cargo, and latch the tailgate before measuring the cargo-floor length.
- Measure floor length. Run the tape from the inside front wall of the box to the inside face of the closed tailgate, along the bed floor. Avoid measuring the exterior body or bumper.
- Check the bed rails. If a cover manufacturer requests a top-rail measurement, measure from its stated points separately. Do not substitute the floor length automatically.
- Measure usable width. Record both the broad interior width and the narrower clearance between the wheelhousings, especially for drawers and rigid cargo.
- Confirm the fitment listing. Compare your results with the product’s exact model-year, cab, bed-length, and installation requirements.
A drop-in liner, factory cargo-management feature, or aftermarket rail system can alter the usable space or mounting points. Check those additions before finalizing an order.
What to Check Before Buying GMC Canyon Bed Accessories
Do not choose a bed accessory by the words “short bed” alone. The 2015–2022 and 2023–2026 Canyon short beds share a 61.7-inch published length, yet the newer cargo box has different width and wheelhouse measurements.
For a tonneau cover, confirm the product is listed for the exact Canyon model years and short- or long-bed arrangement. Rail shape, clamps, tailgate clearance, and any factory-installed bed equipment matter beyond nominal box length.
For a bed liner or cargo drawer, check the floor shape, wheelhouse clearance, tailgate opening, and tie-down locations. If you want to make better use of the space you already have, our guide to truck bed organization ideas covers drawers, slides, dividers, and storage options.
For a toolbox or bed rack, verify the mounting instructions and load limits for your specific installation. Cargo-box volume is not a payload rating; always use the truck’s applicable load information for weight decisions.
The safest buying sequence is to identify the year and bed, measure the physical truck, and select a part with explicit manufacturer-confirmed fitment.
Which GMC Canyon Bed Size Fits Your Needs
The GMC Canyon bed size chart has three practical takeaways. First-generation models generally paired a roughly 61-inch Crew Cab box with a 72.8-inch Regular or Extended Cab box. The 2015–2022 generation offered 61.7- and 74.0-inch beds, including an available Crew Cab long-box configuration. Every 2023–2026 U.S. Canyon uses a 61.7-inch Crew Cab short box.
For cargo planning, check the width between the wheelhousings as well as the floor length. For tonneau covers, liners, or racks, confirm exact model-year fitment rather than relying on bed length alone. If you are uncertain about a particular truck, measure its cargo box before ordering.
What GMC Canyon Bed Size Questions Do Owners Ask
How Long Is the Bed on a 2026 GMC Canyon?
The 2026 GMC Canyon has a 61.7-inch cargo bed, measured at the floor with the tailgate closed. It comes with a Crew Cab short-box configuration, so a factory long-bed option is not available for that model year.
Does the GMC Canyon Come With a 6-Foot Bed?
Yes, on older models. First-generation Regular and Extended Cab trucks used a 72.8-inch long box, and 2015–2022 Canyons offered a 74.0-inch long box. GMC discontinued the factory long-bed option with the 2023 redesign.
What Size Bed Does a 2020 GMC Canyon Crew Cab Have?
A 2020 GMC Canyon Crew Cab may have either the 61.7-inch short box or the 74.0-inch long box, depending on configuration. Check the actual truck or its original equipment information before buying a bed cover.
How Wide Is the GMC Canyon Bed Between the Wheel Wells?
The 2023–2026 GMC Canyon has 45.5 inches between the wheelhousings. The 2015–2022 generation measures 44.4 inches, while archived first-generation specifications show 42.6 inches. Use the figure for your model year when planning wide cargo.
Will a 2022 GMC Canyon Tonneau Cover Fit a 2023 Canyon?
Not necessarily. Both short beds are listed at 61.7 inches long, but the redesigned 2023 bed has different geometry. Buy or transfer a cover only if its manufacturer explicitly lists compatibility with both the 2022 and 2023 GMC Canyon.
