How To Accurately Measure Your Truck Bed For A Tonneau Cover
Remember that frustrating moment when you finally bought that awesome tonneau cover, only to find it doesn’t quite fit your truck bed? Avoiding that disappointment starts with knowing how to measure a truck bed for a tonneau cover accurately. This guide will walk you through the precise steps, ensuring a perfect fit every time. You’ll learn everything from identifying key measurements to understanding different truck bed styles, ultimately saving you time, money, and potential headaches.
Measuring Your Truck Bed Length
Accurately determining the length of your truck bed is the most crucial step in ensuring a proper tonneau cover fit. Inaccurate measurements can lead to a cover that’s too short or too long, compromising functionality and appearance. This section will detail the process and explain why precision is key.
Measuring from the Inside
- Use a measuring tape to measure the inside length of your truck bed from the very front edge (behind the tailgate) to the very back edge (against the cab). Be sure to measure along the deepest part of the bed.
- Record this measurement precisely. Use a notebook or your phone to avoid forgetting it.
This ensures your measurement accounts for the actual usable space. It is important to measure along the longest part of the bed, as some truck beds may have slight variations in depth from side to side. Ignoring this could result in a cover that is too small.
Accuracy is paramount. Even a small error of an inch or two can result in a tonneau cover that is either too loose or excessively tight. Precise measurements guarantee a snug and functional fit.
Measuring from the Outside
- Measure the outside length of the truck bed. This is the measurement from the outer edge of one side to the outer edge of the opposite side. This measurement is usually longer than the interior measurement.
- Note this measurement for comparison with the manufacturer’s specifications.
Some manufacturers provide dimensions based on exterior measurements, so it’s beneficial to have both to compare with the tonneau cover specifications.
Many manufacturers provide detailed instructions on what measurements they use for their cover designs, such as inside bed measurements or outside bed measurements. Understanding this will aid in your purchase decision.
Considering Wheel Wells
- Measure the distance between the wheel wells. This is particularly important for covers that are designed to cover the entire bed.
- Check your tonneau cover manufacturer’s specifications regarding wheel well clearance.
Wheel wells can significantly reduce usable bed space, and not accounting for them will lead to an improperly fitting cover. This is especially true for covers designed to fit flush within the bed.
Some tonneau covers are explicitly designed to accommodate wheel wells, while others might not be. If your cover is not designed to work with your wheel wells, it will likely not fit properly.
Measuring Your Truck Bed Width
Getting the width of your truck bed right is just as important as getting the length correct. This section helps you avoid buying a cover that is too narrow or too wide for your truck bed.
Measuring at the Top and Bottom
- Measure the width of your truck bed at the top (where the sides meet the tailgate).
- Measure the width at the bottom of your truck bed.
This measurement may vary slightly from the bottom, especially in trucks with flared wheel wells. Always take both measurements to ensure a perfect fit for your tonneau cover.
The bottom width of the truck bed is usually narrower than the top, particularly if your truck features wider wheel wells. This is crucial for proper cover installation and optimal performance.
Accounting for Rails and Bedliners
- If your truck bed has any rails or a bedliner, measure the width, taking these features into account.
- Consider the type of bedliner used. Some bedliners add more bulk than others.
Bedliners and rails can slightly alter the dimensions of your truck bed and may impact the fit of your tonneau cover. Ensuring your measurements factor in these elements is crucial for compatibility.
A thick bedliner might cause the tonneau cover to be tighter than anticipated. Always check your tonneau cover’s specifications to see how they might be affected by bedliners.
Measuring Your Truck Bed Depth
While often overlooked, the depth of your truck bed impacts the fit of a tonneau cover, especially those that fold or roll up. This section guides you through the correct measuring technique and its importance.
Measuring at Multiple Points
- Measure the depth of your truck bed at multiple points across its length. The depth can sometimes vary slightly.
- Note the minimum and maximum depths. This information may be needed when selecting a tonneau cover.
The depth of the truck bed might not be perfectly uniform. Measuring at multiple points ensures you have the correct depth information for your tonneau cover.
The minimum and maximum depth provides a range, ensuring the tonneau cover will function well regardless of any minor variations in depth along the truck bed. This helps select a cover that comfortably accommodates this range.
Checking for Obstructions
- Check for any obstructions in the truck bed, such as tie-down hooks or wheel well intrusions, which can affect depth measurements.
- Ensure these are also noted in your overall measurements for a complete assessment.
Tie-down hooks or wheel wells can interrupt the uniform depth of your truck bed. Account for these intrusions when selecting a tonneau cover, ensuring the cover clears any potential obstructions.
Accurate records of obstructions allow you to select a tonneau cover appropriately designed to work around them. Neglecting these points can lead to a misfit and damage.
Types of Tonneau Covers and Their Measurement Needs
Different types of tonneau covers, including soft, hard, folding, and retractable, may require slightly different measurement techniques. Understanding these nuances is key to selecting the right cover and ensuring proper fit. This section discusses these aspects.
Soft Tonneau Covers
Soft tonneau covers usually require less precise measurements compared to hard covers. However, you still need to measure the length and width accurately to avoid gaps or an overly tight fit.
Hard Tonneau Covers
Hard tonneau covers often require more precise measurements as they are typically more rigid and less adaptable to minor discrepancies. Ensure you have accurate measurements before purchasing.
Folding and Retractable Tonneau Covers
Folding and retractable tonneau covers often need precise measurements for proper operation. Inaccurate measurements can lead to issues with the cover’s folding or retracting mechanisms. Depth is especially important for these types.
Common Myths about Tonneau Cover Measurement
Myth 1: Online Measurements Are Always Accurate
Relying solely on online measurements without your own physical measurements is a recipe for disappointment. Manufacturer dimensions might be generalized or slightly inaccurate, making it crucial to do your own precise measuring.
Myth 2: One Measurement is Sufficient
Taking only one measurement is insufficient. You need length, width, and depth measurements from multiple points to guarantee an appropriate fit. Ignoring this will likely result in a tonneau cover that doesn’t fit properly.
FAQ
What happens if I measure incorrectly?
Incorrect measurements will likely result in a tonneau cover that doesn’t fit your truck bed properly. This can lead to gaps, difficulty closing the cover, and even potential damage to the cover or your truck bed.
Do I need to measure the tailgate?
While the tailgate itself doesn’t generally need measuring for tonneau cover fit, ensuring its functionality and clearance with the cover is important. Verify the cover’s compatibility with your truck’s specific tailgate.
Should I account for my truck’s bed’s angle?
Usually, you can disregard minor angles in your measurements. But, significant changes in bed angle might need to be accounted for. Consult your tonneau cover manufacturer’s guidelines for trucks with unusual bed angles.
Can I use a flexible measuring tape?
Yes, a flexible measuring tape is ideal. It allows you to navigate curves and irregularities in your truck bed effectively, ensuring accurate measurements.
What if my truck has a spray-in bedliner?
A spray-in bedliner will slightly alter the dimensions of your truck bed. Take your measurements after the bedliner is installed to ensure an accurate fit for your tonneau cover.
Final Thoughts
Accurately measuring your truck bed is the foundation for a successful tonneau cover installation. By carefully following the steps outlined in this guide, you can avoid the common pitfalls of incorrect measurements. Remember to consider all three dimensions—length, width, and depth—and account for any features like bedliners or rails. Taking the time to do this will guarantee a perfect fit, enhancing your truck’s functionality and aesthetics for years to come. Now go ahead and get measuring!
