What Roof Tent Size Fits My Car?
Calculate roof tent load compatibility using roof tent weight, total occupants weight, and vehicle dynamic roof load limit.
Enter your measurements
Before choosing a product, measure roof tent weight, total occupants weight, and vehicle dynamic roof load limit. The what roof tent size fits my car tool uses those values to calculate roof tent load compatibility and makes the limiting measurement clear.
- Roof tent weight — Required
- Total occupants weight — Required
- Vehicle dynamic roof load limit — Required
- Rack dynamic load limit — Required
- Vehicle static roof limit — Required
Roof tent load compatibility
Enter the measurements above to calculate roof tent load compatibility.
How the calculation works
V12 calculation: dynamicLimit=min(vehicleDynamicRoofLimit,rackDynamicLimit); travelPass=tentWeight≤dynamicLimit; staticLoad=tentWeight+occupantWeight; campPass=staticLoad≤vehicleStaticRoofLimit; overallPass=travelPass AND campPass. This is the implementation specification for this calculator.
Worked example
Example: Roof tent weight = 6.05 kg; Total occupants weight = 16.48 kg; Vehicle dynamic roof load limit = 61.11 kg; Rack dynamic load limit = 118.59 kg; Vehicle static roof limit = 76.66 kg. Result: Fits; Camp Pass = Pass; Static Load = 22.53 kg; Travel Pass = Pass.
Before you decide
Enter the dimensions that will exist in real use, not an approximate catalogue category. This page calculates the stated geometry or quantity only; product-specific construction or installation details can still affect the final choice. For what roof tent size fits my car, the limiting result on this page is roof tent load compatibility.
Direct measurement/geometry calculation. No external reference is required for the arithmetic itself; the result is derived only from the user-entered measurements and the formula stored in calculationLogicJson.
