Whether you’re a seasoned truck enthusiast or a first-time owner, this guide will empower you with the knowledge to make the most out of your vehicle’s cargo space.
Measuring the Length of Your Truck Bed
To accurately measure the length of your truck bed, begin at the inner edge of the bulkhead—the vertical wall closest to the cab. This surface serves as the starting point for your measurement. Extend your tape measure straight to the inner edge of the tailgate, ensuring it is fully lowered if possible for the most precise reading. Avoid measuring over the top rails, as these do not represent the usable length of the bed.
When measuring, keep the tape measure taut and parallel to the bed floor to prevent inaccuracies. For trucks with bed liners or covers, measure underneath these accessories, as they can add to the apparent length but not the usable cargo space. It is also essential to note whether the tailgate is closed or open, as this affects the total length, particularly if you plan to transport longer items.
Determining the Width of the Truck Bed
Truck bed width is typically measured in two locations: between the wheel wells and from sidewall to sidewall. To measure the width between the wheel wells, place the tape measure inside the bed just above the wheel wells and measure the distance across. This measurement is critical because the wheel wells often limit the width of flat cargo.
Next, measure the overall width by extending the tape measure from the inner sidewall to the opposite sidewall, just below the top rail. This dimension represents the maximum width and is useful for determining the size of large cargo or accessories like bed extenders.
When measuring width, keep in mind:
- The presence of bed liners or protective coatings may slightly reduce internal width.
- Some truck beds have tapered sidewalls, so measure at multiple points for accuracy.
- Consider whether you need the width for cargo capacity or for accessory fitting.
Measuring the Height and Depth of the Truck Bed
To measure the height (or depth) of the truck bed, position the tape measure vertically from the bed floor to the top edge of the sidewall. This measurement indicates the maximum vertical space available for cargo and is particularly important when selecting bed covers or storage boxes.
If your truck bed has a liner, measure from the liner floor to the sidewall edge to get a precise indication of usable height. Additionally, for trucks with bed caps or tonneau covers, measure the height with these accessories installed if you intend to use them regularly.
Using a Measurement Table for Reference
Below is a table summarizing typical truck bed measurements for common pickup models. Use this as a guideline, but always verify your specific truck’s dimensions as variations exist even within the same model year.
| Truck Model | Bed Length (inches) | Width Between Wheel Wells (inches) | Total Bed Width (inches) | Bed Depth (inches) |
|---|---|---|---|---|
| Ford F-150 (Standard Bed) | 78.9 | 50.6 | 66.0 | 21.4 |
| Chevrolet Silverado 1500 (Short Bed) | 67.0 | 50.6 | 65.7 | 21.3 |
| Ram 1500 (Crew Cab Short Bed) | 67.4 | 50.3 | 65.0 | 21.3 |

Tips for Accurate Measurement
To ensure your measurements are as accurate as possible, consider these professional tips:
- Use a rigid tape measure or a laser distance measurer for better precision.
- Measure multiple times and average the results to minimize errors.
- Record measurements in both inches and centimeters if needed.
- When measuring, have an assistant hold the tape measure to maintain tension and alignment.
- Take notes on any accessories or modifications that may affect bed size.
- Photograph the measurement process for future reference or verification.
By carefully measuring each dimension of your truck bed, you can confidently select the right accessories, plan cargo loads, and ensure compatibility with storage solutions.
Determining the Length of Your Truck Bed
Accurately measuring the length of your truck bed is essential for selecting the right accessories, covers, or cargo management solutions. To measure the length, follow these steps carefully:
- Open the tailgate fully to access the bed’s interior.
- Use a tape measure that extends beyond the expected bed length (typically 6-8 feet).
- Measure from the inside edge of the bulkhead (the wall behind the cab) straight to the inside edge of the tailgate.
- Ensure the tape measure lies flat along the bed floor without sagging or bending.
- Record the measurement in inches or feet for precision.
This length measurement excludes the tailgate itself, as the tailgate position can vary and is generally not considered part of the usable bed length unless specified otherwise.
Measuring the Width of Your Truck Bed
The width of the truck bed influences the size of cargo that can fit and the compatibility with bed liners or toolboxes. To measure the width:
- Measure at the widest point inside the bed, typically near the rear where the wheel wells are furthest apart.
- Take two key width measurements:
- Between the wheel wells: Measure the distance from the inside edge of one wheel well to the inside edge of the opposite wheel well.
- Overall width: Measure from the inside of one bed wall to the inside of the opposite bed wall. This measurement is useful for flat-bed accessories.
- Use a rigid tape measure and ensure it is level and straight across the bed floor.
| Measurement Type | Location in Bed | Typical Use |
|---|---|---|
| Width between wheel wells | Narrowest internal width | For cargo that fits between wheel wells |
| Overall width | Widest internal width at bed sides | For accessories covering the entire bed width |
Measuring the Height and Depth of Your Truck Bed
Understanding the height and depth of the truck bed helps with determining cargo volume and the fit of bed extenders or liners. To measure height:
- Measure from the floor of the bed straight up to the top of the bed rails.
- Take measurements at multiple points, especially near the wheel wells and the bed’s front and rear, as variations can exist.
Depth measurement often refers to the vertical distance inside the bed, which affects how much cargo can be stacked.
- Record the height in inches for accuracy.
- For volume calculations, multiply the length, width, and height to estimate the cubic capacity of the bed.
Additional Considerations When Measuring Your Truck Bed
Several factors can influence the accuracy and relevance of your measurements:
- Bed liners and mats: If your truck bed has a liner or mat, decide whether to measure over or under it based on your intended use (e.g., fitting a cover over the liner).
- Tailgate position: Some measurements may require the tailgate to be closed, especially if measuring total length including the tailgate. Confirm your purpose before measuring.
- Irregular shapes: Some truck beds have tapered or curved walls. In such cases, take multiple measurements at different points and use the smallest dimensions for critical fitting purposes.
- Double-check measurements: Use a helper to hold the tape measure or mark measurements for accuracy.
Using Your Measurements to Select Accessories
Once you have precise dimensions of your truck bed, you can confidently select compatible products. Common accessories that require accurate bed measurements include:
- Bed liners and mats (drop-in or spray-in)
- Tonneau covers (roll-up, folding, or retractable)
- Bed extenders and dividers
- Toolboxes and storage systems
- Cargo racks and tie-down anchors
Maintaining a record of your truck bed dimensions in both inches and centimeters can facilitate easier comparison when shopping or consulting product specifications.
| Accessory Type | Critical Measurement | Measurement Notes |
|---|---|---|
| Bed Cover | Length and width (overall) | Measure with tailgate closed; include bed rails |
| Bed Liner | Length, width between wheel wells, height | Measure inside the bed without liner thickness |
| Toolbox | Width between wheel wells, height | Ensure clearance above wheel wells |
| Bed Extender | Length with tailgate down | Measure from bulkhead to tailgate end when open |
Professional Insights on Measuring Your Truck Bed Accurately
James Thornton (Automotive Engineer, Truck Innovations Inc.) emphasizes that “To measure the bed of your truck correctly, start by measuring the length from the inside of the bulkhead to the inside of the tailgate.
