Measuring your RV's size is essential from selecting the right storage space or parking spot to ensuring smooth maneuverability on the road. Knowing the length, width, and height of your RV helps you avoid potential issues and complies with size limits at many campgrounds and national parks.

Do you really know how to measure your RV? This guide will walk you through the process of accurately measuring your RV, helping you make informed decisions and ensuring a safe and enjoyable experience on all your travels.

Before You Measure RV and Equipment Size

Before you start measuring your RV or camping trailer, there are a few essential steps to take. First, gather the right equipment: you'll need a long, accurate tape measure that can span the entire length of your RV. Make sure to attach all the gear you plan to bring on your trip, such as external storage units, racks, or propane tanks, as these add to the overall length. Next, measure different sections of the RV, especially if you have a fifth wheel or travel trailer.

Take measurements both with and without the towing vehicle, from the back bumper to the tongue jack, including any accessories. It’s also smart to keep these measurements handy—store them in your phone or note them down in your RV manual.

How to Measure Your RV - A Complete Guide

Accurate measurements are crucial for any RV, whether you’re ensuring it fits into a campsite or meets legal road limits. Now, let’s read the complete guide on how to measure the dimensions of different types of RVs.

Travel Trailer

Travel trailers, ranging from compact teardrop models to more spacious versions, offer flexibility and convenience for RV enthusiasts. They typically range in length from 16 to 20 feet and have an average width of 8 feet, making them suitable for towing with most family vehicles.

How to Measure a Travel Trailer?

1. The Length:
   For standard travel trailers, R-Pods, folding camping trailers, molded fiberglass trailers, and teardrop trailers, measure the body length from the front bumper to the rear bumper. Do not include the tongue or hitch, as these parts are not covered by most trailer covers.
2. The Height:
   Measure from the roofline of the trailer down to the ground. This measurement should include any permanent fixtures like antennas or AC units if your cover accounts for these features.

Fifth Wheel

Fifth wheels are spacious towable RVs that offer more living space and comfort than travel trailers. They connect to the bed of a pickup truck, providing greater stability and a better turning radius. Fifth wheels can range from under 20 feet to 40 feet in length, with heights typically between 11’6” and 13’6” due to federal regulations.

How to Measure a Fifth Wheel?

1. The Length:
   Measure from the tip of the nose to the rear bumper, excluding the hitch. This helps determine parking, storage, and towing requirements.
2. The Height:
   Measure from the ground to the highest point, including any accessories like AC units or antennas. Manufacturers often list both 'Exterior Height' and 'Exterior Height (with A/C)', so check both for accuracy.
3. Additional Measurements:
   Measure the height when hitched to ensure there’s no “nose high” setup. Consider any extra attachments to ensure safe travel and avoid low-clearance routes.

How to Measure a Camper Van's Length and Width?

Class A Motorhome

Class A motorhomes are the largest and most spacious RVs.They vary in size, with lengths ranging from 25 to 45 feet and heights typically between 11 to 13 feet. Their width, usually between 8 and 8.5 feet, ensures they fit safely within highway lanes, but slideouts can add extra width when parked.

1. Measure the Length:
   Measure the body of the Class A motorhome from bumper to bumper. This measurement is crucial for determining the RV's fit in campsites and parking spaces and for planning your travel routes.
2. Measure the Height:
   Measure from the roofline to the ground to determine the total height of the motorhome. Be sure to include any roof-mounted accessories like air conditioning units or antennas.

Class B Motorhome

Class B motorhomes, or camper vans, are the smallest, typically ranging from 17 to 25 feet in length, 9 to 11 feet in height, and around 8 feet in width. Their smalle size makes them ideal for weekend trips and navigating city streets with ease. However, they may not be the best choice for full-time living or larger families.

1. Measure the Length:
   Measure from the front bumper to the rear bumper to determine the total length. This measurement is essential for parking, storage, and understanding how much room you have to maneuver.
2. Measure the Height:
   Measure from the ground to the highest point on the roofline. Include any roof-mounted accessories, such as air conditioning units or antennas.

Class C 

Class C motorhomes are a versatile choice, falling between the larger Class A motorhomes and the smaller Class B camper vans. Built on a cutaway van chassis, these RVs typically range from 25 to 35 feet in length and can accommodate up to eight people. With an average length of about 28 feet, a width of 8 feet, and heights reaching up to 10.8 feet, Class Cs offer a spacious interior without being overly cumbersome.

1. Measure the Length:
   Measure the length of the Class C motorhome from the front bumper to the rear bumper. This will help determine the vehicle's fit in various parking spots and storage areas.
2. Measure the Height:
   Measure from the roofline to the ground to get the overall height. Include any roof-mounted accessories like air conditioning units or antennas, though most covers are designed to accommodate these extras.
