RV Leveling Calculator

Calculate the block height needed at each wheel to level your RV based on how far off-level it is front-to-back and side-to-side.

How to Use This Calculator

Enter front-to-back off level (inches) using a bubble level on a flat surface inside the RV.
Set side-to-side off level (inches), wheelbase, and track width.
Review the required block height for each wheel position to achieve level.
Level side-to-side first, then front-to-back -- use interlocking leveling blocks for stability.

What each input means

Front-to-Back Off Level: Positive = front is higher, negative = rear is higher. Measure with a level on the floor.
Side-to-Side Off Level: Positive = left side is higher, negative = right side is higher.
Wheelbase: Distance between front and rear axles in inches. Used for reference.
Track Width: Distance between left and right wheels in inches.

Front Block Height: Height to raise the front wheels. 0 if front is already lower.
Rear Block Height: Height to raise the rear wheels. 0 if rear is already lower.
Left Side Block Height: Height to raise the left wheels. 0 if left is already lower.
Right Side Block Height: Height to raise the right wheels. 0 if right is already lower.
Wheel Positions Needing Blocks: Number of wheel positions that need leveling blocks (0-4).
