Ram ProMaster Dimensions

When I was deciding which van to buy for my DIY camper van build, I researched the Ram ProMaster, Ford Transit and Mercedes Sprinter. Each one has it’s pros and cons, and ultimately I chose the Ford Transit – but the Ram ProMaster Dimensions for width (being the widest van on the market) really caught my eye because it allows you to sleep sideways and save space on your van layout.

When it comes to choosing the right vehicle for van life, finding the perfect balance between space, maneuverability, and reliability is crucial. Enter the RAM ProMaster, one of the most popular vans in the van life community.

The Ram ProMaster dimensions vary based on model. There are several configurations for this van, and the 2500 high roof is the most popular for van life.

In this article, I outline the interior and exterior dimensions of the Ram ProMaster that are important to consider when planning a van build.

Ram ProMaster Sizes

There are several different size options for the Ram ProMaster van which impact the overall dimensions. Models will vary based on the wheelbase and the roof height.

In general, Ram ProMaster is the widest van on the market, compared to the Ford Transit dimensions and the Mercedes Sprinter van dimensions. The Ram ProMaster is also known for having a boxier interior, which makes it easier to frame for a van conversion.

Ram ProMaster Wheelbase Options

The Ram ProMaster is available in 118”, 136”, 159” and 159” extended wheelbase.

Ram ProMaster Height Options

The Ram ProMaster comes in three height options: low roof, high roof and super high roof. The super high roof option debuted with the 2023 model, so if you’re buying an older used model this height may not be an option.

The high roof option is the most popular Ram ProMaster for van life, as it allows most people to stand up fully inside the van. However, I expect that the super high roof will become more and more popular now that it’s available on newer models. Having more interior height means you can add more van insulation and still have head clearance.

Below are two charts which show the Ram ProMaster interior dimensions, as well as the exterior dimensions, in feet.
