When buying a truck canopy or tonneau cover, guessing your bed size is the fastest way to end up with a costly mistake. Even a one- or two-inch discrepancy can lead to water leaks, poor sealing, or a cover that simply won't install.
Measuring your truck bed is incredibly easy andย takes just two minutes. Here is the foolproof way to get the exact dimensions you need.
The Golden Rule: Always Measure the INSIDE
Your truck bed length is the usable distance from the inside of the front wall (bulkhead) to the inside of the tailgate. Never measure the exterior sheet metal of the truck body.
๐ ๏ธ Step 1: Gather Your Tools
All you need is a standard metal tape measure, along with a pen and paper to record your numbers.
๐ Step 2: Find Your Start and End Points
-
The Start Point (Bulkhead): Push the metal hook of your tape measure flat against the inside front wall of the truck bed (the vertical metal wall directly behind the cab/rear window).
-
The End Point (Tailgate): We recommend doing this with the tailgate closed. Run the tape measure straight down the center of the bed until it touches the inside surface of the closed tailgate. (If you must measure with the tailgate open, pull the tape to the exact inside edge where the tailgate rests when closed).
-
Keep it Straight: Ensure the tape measure is perfectly straight and flat along the floor. Do not measure diagonally or route the tape over the wheel wells.
๐ข Step 3: Read and Convert
Note the measurement in inches. In North America, truck canopies and covers are usually categorized in feet. To find your size, simply divide your inch measurement by 12 (for example, 78 inches รท 12 = 6.5 feet).

~96 to 98 Inches = 8.0 ft. (Long Bed โ Common on Heavy-Duty Work Trucks)
โ ๏ธ Two Pro Tips to Avoid Mistakes
-
Beware of Drop-in Bedliners: If your truck has a thick, aftermarket plastic drop-in bedliner, it can eat up 1 to 2 inches of space. When measuring, try to push against the actual metal underneath, or mentally add the thickness of the plastic liner back into your total length to get the true inner dimension.
-
Double-Check with Your VIN: If you measure your bed and still feel unsure, look for the vehicle information sticker located inside the driver's side door jamb. You can also run your VIN (Vehicle Identification Number) online through a decoder to pull up the exact factory bed specifications for your specific truck.
