How Many Gallons of Bed Liner Do I Need to Paint My Truck?

Painting your truck is a great way to add a personal touch and make it look even more attractive. Applying bed liner to the exterior of your truck adds an extra layer of protection while also giving it a unique look. But before you can start painting, you need to figure out how many gallons of bed liner you’ll need.

The amount of bed liner you’ll need depends on several factors, including the size and shape of your truck, as well as the type of coating you want to use. Generally speaking, most trucks require between two and four gallons of bed liner, depending on their size. If your truck is larger or if you want to apply multiple coats, then you may need more.

When calculating how much bed liner you need for your truck, it’s important to consider the surface area that will be covered.

Start by measuring the length and width of your truck’s body panels and multiplying them together to get the total square footage. Then divide this number by 250 (the approximate coverage rate per gallon) to get an estimate for the amount of gallons needed.

It’s also important to factor in any additional areas that require coverage such as wheel wells or side steps. These areas may require extra product as they can be tricky to cover properly with just one coat. Additionally, keep in mind that some bed liners come in different finishes or colors which may require additional product when applying multiple coats.


When it comes to painting your truck with bed liner, there are several factors that will affect how much product is needed. To make sure that you don’t run out halfway through the job, measure the surface area of your vehicle carefully and do some calculations before making a purchase. With proper planning and preparation, you’ll have enough bed liner on hand to give your truck a great new look!
