How to Measure a Truck Bed for a Tonneau cover?

In order to snuggly fit the tonneau cover on the truck bed, you can follow these steps.

1- Determine the Type of Truck Bed

The first step is to determine the type of truck bed you have. Standard beds are typically 8 feet long, while short beds are usually 6 or 6.5 feet long.

2- How to Measure the Length of Truck Bed?

To measure the length of the truck bed, measure from the inside of the tailgate to the inside of the bulkhead (front of the bed). For example, if you have a 2019 Ford F-150 with a standard bed, the length would be 8 feet or 96 inches.

3- How to Measure the width of the bed?

Measure the width of the truck bed at the widest point. This is typically at the top of the bed near the cab. For example, if you have a 2019 Ford F-150 with a standard bed, the width at the widest point would be 70 inches.

4- Measure From the Top to Tailgate – Closed

Measure the distance from the top of the bed to the top of the tailgate when it is closed. Like, if you have a 2019 Ford F-150 with a standard bed, the distance would be 22 inches.

5- Look for Obstructions

Check for any obstructions that may affect the fit of the tonneau cover, such as bed liners or bed extenders. If you can’t remove the obstruction and your truck bed cover is long, then you need to shorten the truck bed cover.

6- Manual Guide Consideration

Consult the tonneau cover manufacturer’s guide to determine the correct size for your truck bed.

If you’re looking at a tonneau cover made by Truxedo, they may recommend a cover that fits a 2019 Ford F-150 with an 8-foot bed, a width of 70 inches, and a height of 22 inches.

7- Choose the Right Tonneau Cover

Choose the right tonneau cover that fits your truck bed and your needs. For example, if you prioritize security and weather resistance, you may choose a hardcover made of fiberglass or aluminum. If you’re looking for a more affordable option, a soft vinyl or canvas cover may be a better choice

How to Measure the square feet?

If you want to measure the bed cover in square feet, you can follow this method:

  • To measure the square feet, multiply your width(inches) x length(inches). So it will give you a proper calculation of your square footage adjustment. 
  • Also, if you want your measurements in feet, divide the values of inches by 12.

How to find Truck Bed Size?

To find your truck bed size, measure the length from the inside of the tailgate to the inside of the bulkhead (front of the bed), measure the width at the widest point, and measure the distance from the top of the bed to the top of the tailgate when it’s closed. Consult the owner’s manual or manufacturer’s website for standard bed lengths.

How to find truck bed size by VIN?

Your car’s VIN (vehicle identification number) determines the size of your truck bed. You may find the VIN by searching in the door frame on the driver’s side or at the bottom of your windshield.

The VIN is useful for indirectly determining your truck bed’s size. Using the VIN, you can gather information about the vehicle’s make, model, and year, which can then determine the most likely bed size.

For example, if you have a 2019 Ford F-150 with a VIN of 1FTEW1EP1KFA12345, you can determine that it is an F-150 made by Ford in 2019. You can consult the owner’s manual or visit the manufacturer’s website to determine the bed length using this information. In this case, the 2019 Ford F-150 comes in three-bed lengths: 5.5 feet, 6.5 feet, and 8 feet.

How should a tonneau cover fit?

A tonneau cover should fit snugly on your truck bed without gaps or sagging. The cover should be secured firmly to the bed with clamps or other fasteners to prevent any movement while driving.

When closed, the cover should not obstruct the operation of the tailgate and should allow for easy access to the truck bed. A properly fitting tonneau cover will provide maximum protection for your cargo and improve your truck’s overall appearance.
