Toyota Tundra Bed Size Chart: All Generations And Cab Configurations 2000-2026
The Toyota Tundra has been built in three distinct generations since 2000, and the bed dimensions changed meaningfully at each redesign.
A tonneau cover, bed liner, or truck bed tent that fits a 2019 Tundra will not fit a 2023 Tundra, and a first generation Tundra from 2003 uses a completely different bed than either of them.
Matching the right accessory to your Tundra starts with knowing which generation you own, which cab style it has, and which of the three bed lengths came on that build.
This chart breaks down every Tundra bed length by generation, cab configuration, and model year, along with the width and depth measurements that determine what actually fits inside the box.

How Toyota Tundra Bed Sizes Are Measured
Toyota markets Tundra beds by their rounded length in feet, such as 5.5 feet or 6.5 feet, but two numbers matter more when you are buying accessories. The first is the floor length, measured from the front bulkhead to the tailgate, which is what determines whether a specific tonneau cover or bed tent will stretch to fit.
The second is the width between the wheel wells, which sets the maximum size of flat cargo like plywood or a 4×8 sheet of drywall that can lay flat on the floor.
Independent measurement sources sometimes report slightly different width and depth figures for the same generation because some measure wall to wall at the top of the bed rail while others measure the usable floor width lower down. Both figures are listed below where they differ, so you can match the number to the point your accessory manufacturer specifies.
First Generation Toyota Tundra Bed Dimensions For 2000 To 2006
The first generation Tundra, sold from 2000 through 2006, offered three bed and cab combinations. Toyota did not offer a Double Cab body style until the 2004 model year, and that configuration only came with one bed length.

| Cab Style | Bed Length | Approx. Length | Approx. Width | Approx. Depth |
|---|---|---|---|---|
| Regular Cab and Access Cab | 8 ft long bed | 98.2 in | 62.8 in (wall to wall) | 16.7 to 17.2 in |
| Access Cab | 6.2 ft standard bed | 74.3 to 76.5 in | 62.8 in (wall to wall) | 16.7 to 17.2 in |
| Double Cab | 6.2 ft standard bed | 74.3 to 74.7 in | 63.3 in (wall to wall) | 20.7 in |
The Access Cab standard bed length is reported inconsistently across parts fitment listings, with figures ranging from 74.3 to 76.5 inches depending on where the measurement starts. Owners cross shopping a bed cap or tonneau cover for a 2000 to 2006 Access Cab should confirm the exact figure against the specific product’s fitment chart rather than the truck’s spec sheet alone, since Toyota’s official brochures for this generation are no longer published online.
The Double Cab body style, added partway through the first generation, kept a similar floor length to the Access Cab but used a noticeably deeper box, roughly 20.7 inches compared to about 17 inches on the other cab styles.
Toyota Tundra owners researching whether their Ram counterpart uses the same accessory sizing can check the Dodge Ram bed size chart for a side by side comparison, since bed cap and rail manufacturers occasionally cross list compatible dimensions between full size trucks.
Second Generation Toyota Tundra Bed Dimensions For 2007 To 2021
The second generation Tundra ran from 2007 through 2021 and introduced the three bed lengths that carried into the current generation. This was also the first year Toyota offered a short bed on the CrewMax cab.
| Cab Style | Bed Length | Length | Available On |
|---|---|---|---|
| CrewMax | 5.5 ft short bed | Approx. 66 to 66.7 in | CrewMax only, all years 2007 to 2021 |
| Double Cab and CrewMax | 6.5 ft standard bed | Approx. 78.7 in | Both cab styles |
| Double Cab | 8.1 ft long bed | Approx. 96.5 to 97 in | Double Cab only |
Width and depth held steady through this generation at approximately 66.4 inches wall to wall (about 58.7 inches at the usable floor width) and approximately 22.2 inches deep at the rail, narrowing to about 20.9 inches at the floor. The gap between the wheel wells measures approximately 48.5 to 50 inches across the generation, which is tight enough that a full 4×8 sheet of plywood will not lay flat without resting on the wheel wells.
The second generation bed was steel, not the aluminum reinforced composite Toyota switched to for the third generation, which matters for anyone comparing rust resistance or the holding strength of bed mounted tie downs and racks.

Third Generation Toyota Tundra Bed Dimensions For 2022 And Later
The current generation Tundra, in production since the 2022 model year, kept the same three bed lengths as the second generation but changed which cab styles they pair with and switched the bed material to a composite panel over an aluminum frame.
| Cab Style | Bed Length | Interior Length | Trim Availability |
|---|---|---|---|
| CrewMax | 5.5 ft short bed | 65.6 in | Standard on CrewMax |
| Double Cab and select CrewMax | 6.5 ft standard bed | 77.6 in | Standard on Double Cab, optional on select CrewMax trims |
| Double Cab | 8.1 ft long bed | 96.5 in | SR and SR5 Double Cab only |
Width and depth carry over closely from the second generation, at approximately 58.7 inches of usable floor width and approximately 66.4 inches wall to wall, with a floor depth of approximately 20.9 inches and roughly 20.9 to 22.2 inches at the rail depending on measurement point.
Toyota’s own product pages confirm the three bed lengths and the composite bed construction without publishing exact width and depth figures, so the width and depth numbers above should be treated as approximate until confirmed against the build sheet or door jamb label of the specific truck.
How Cab Style Limits Which Tundra Bed Length You Get
Cab choice is the biggest factor in which bed length is even available to you, and this pairing has shifted with every generation.
On the current third generation Tundra, CrewMax buyers choose between the 5.5 ft and 6.5 ft beds, and the 6.5 ft option is limited to select higher trims rather than being available across the lineup.
Double Cab buyers choose between the 6.5 ft standard bed and the 8.1 ft long bed, but the 8.1 ft configuration is restricted to the SR and SR5 trims, so a Limited or Platinum Double Cab will not be available with the long bed.
This differs from the second generation, where the 8.1 ft long bed was available across more Double Cab trim levels, and from the first generation, where the CrewMax cab style did not exist at all and the 5.5 ft short bed was not offered until the redesign.
What Tundra Bed Size Means For Tonneau Covers And Tents
Bed length is the single most important number for fitting a tonneau cover, since covers are built to a specific floor length and will not stretch or shrink to cover a different generation’s box, even when the labeled bed size sounds the same. A 6.5 ft cover built for a 2015 Tundra will not fit a 2023 Tundra’s 6.5 ft bed cleanly, because the interior length and rail profile changed between generations.
The same logic applies to truck bed tents, which anchor to the bed rails and stretch across the full floor length. A tent rated for a 5.5 ft bed will sit loose and lose weather sealing on a 6.5 ft bed, and it will not fit at all on an 8.1 ft long bed.
Buyers cross shopping accessories built for other Toyota trucks can reference the tonneau cover options built for the Toyota Tacoma to understand how fitment charts are typically structured,
though Tacoma covers themselves will not fit a Tundra due to the size difference between the two trucks. The same applies to bed tents designed for the Toyota Tacoma, which use the Tacoma’s narrower rail spacing and will not transfer to a Tundra bed.
How Bed Width Affects Toolbox And Cargo Fit
Toolboxes that mount across the bed rails, known as crossover or saddle boxes, are sized to the width between the bed walls rather than the floor length, which is why the same toolbox can often fit multiple bed lengths within one generation but not across generations.
The approximately 66.4 inch wall to wall width on second and third generation Tundras is wide enough for most full size crossover boxes designed for other full size trucks, but first generation Tundra owners with the narrower 62.8 to 63.3 inch width should confirm clearance before ordering, since a box built for a modern full size bed may overhang the rails on an older Tundra.
For reference on how crossover toolbox sizing is typically presented by generation and bed width, the toolbox guide built for the Toyota Tacoma walks through the same width to fitment logic on a narrower midsize bed, which is useful context even though the specific boxes covered there are sized for the Tacoma rather than the Tundra.
Frequently Asked Questions About Toyota Tundra Bed Sizes
Does every Toyota Tundra generation offer the same three bed lengths?
No. The first generation, from 2000 to 2006, offered only two effective bed lengths, an 8 ft long bed and a roughly 6.2 ft standard bed, and did not have a CrewMax cab. The 5.5 ft short bed did not appear until the 2007 model year at the start of the second generation.
What is the widest Toyota Tundra bed for hauling flat material?
All three current generation bed lengths share the same width, so a full size sheet of plywood or drywall will not lay flat on any Tundra bed length without resting on the wheel wells, since the gap between the wells is narrower than 48 inches across every generation.
Will a bed cover made for a 2020 Tundra fit a 2023 Tundra?
Not reliably. Both are second and third generation trucks with similar bed lengths, but the composite bed panel and rail profile changed at the 2022 redesign, so covers should be matched to the specific generation rather than the labeled bed length alone.
How can I confirm my exact Tundra bed length before buying an accessory?
Check the door jamb label or original build sheet for the bed code, or measure the floor length from the front bulkhead to the inside of the tailgate with the tailgate closed, then compare that figure to the generation specific chart above rather than relying on the trim name alone.
