You’ve decided to get a tonneau cover for your truck bed and protect your cargo and interior accessories, and improve your gas mileage; so, now which size do you need? Tonneau covers are identified by part numbers associated with the Year, Make, and Model of your truck and the bed length. Measuring your truck bed for a tonneau cover is pretty straightforward. A measuring tape will help you determine the length of the bed. Let’s make sure you get the right fit. 

What to Consider When Measuring a Tonneau Cover

Before digging into measuring your truck bed, make sure you can purchase one. If your truck has any built-in or after-market accessories then you may be obligated to buy a specific tonneau cover built for those accessories. Some truck accessories prevent tonneau covers from being placed on the truck bed, such as truck racks and tool boxes. 

Also, you’ll want to consider the bed liner as it can impact the space that tonneau covers need to cover. To make sure you get the right size, measure the space inside the bed liner instead of over it as you may need to drill or cut through the bed liner when attaching the bed rails. Spray on bed liners that are shot on thick can reduce the between bed measurement.

Measure Your Truck Bed for Tonneau Covers

When measuring your pickup truck bed for a tonneau cover be sure to measure the inside dimension from the bulkhead to the tailgate. (Example: 5 feet 8 inches)
