A General Guide to Measure your RV for an RV Cover


The standard system of measurement used is always feet and inches (n’ n”). When ordering a cover, manufacturers and suppliers provide length ranges for you to initially choose from (e.g., 41′ – 44′ or 26’1″ – 28’6″), but height and width specifications can be found if you want to confirm these before purchasing the cover.

Length: Measure the longest point from the front to the rear of the RV. Always include bumpers, the spare tire and the ladder (specific instructions for each type of RV are given below). Hitches and tongues are not included. Propane tanks are not usually covered either but covers for these are available separately.

Height: Measure the RV sidewalls, from the top of the roofline down toward the outside frame. Do not stop at the top of the wheel well! Exclude any roof-mounted accessories, vents, and A/C units, as well as ground clearance.

Width: Stand facing the front of your RV, then measure from side to side at the widest point. Exclude mirrors and awnings.

Important Tip: if your length measurement is on the cusp of the higher end of the length range for the cover you have your eye on, there is no need to go up to a bigger size. This is because RV covers are made with extra fabric. The extra fabric makes it easier to gather and fold the cover under when tightening the cinch ropes and straps, and it ensures that RVs on the longer side of the scale still have complete coverage. Additionally, covers are made a little bigger to account for any roof-mounted accessories, vents and A/C units. Going with the next size up could mean having a cover that is much too big!

For example: Say your RV measures 28’6″, and your choice of length ranges is between 26’1″ – 28’6″ or 28’7″ – 30’1″, you will want to order the smaller version of the cover (26’1″ – 28’6″). However, if your RV length measures 28’7″, then you will want to order the larger version (28’7″ – 30’1″).
