That is a great question, and one that must be answered in order to understand the different options when it comes to truck bed sizes.
It is important to understand the differences between different trucks and how they can affect the size of the bed.
The most common type of pick-up truck is a full-size truck. These vehicles typically have beds that range from six feet in length to eight feet in length.
They have a wheelbase of anywhere from 118 inches to 160 inches depending on the model. The width of these beds range from 50 inches to 80 inches depending on the model.
Mid-size trucks typically have beds ranging from four feet in length to five feet in length. The wheelbase ranges from 109 inches to 125 inches, with widths ranging from 48 inches to 60 inches. The beds may be slightly wider or narrower than full-size trucks due to the difference in wheelbase.
Compact pickups are smaller than their full-size or mid-size counterparts, but they still come with beds ranging from four feet in length to five feet in length. These beds may have wheelbases of anywhere from 97 inches to 117 inches, with widths ranging from 44 inches to 56 inches.
In conclusion, while there are some variations in truck bed size based on model, it is safe to say that there is generally a universal size among pickup truck beds. This means that you should be able to find a size that works for your needs regardless of what kind of truck you are looking at.
