Size guide
How to choose the right size dog crate
Choosing the right size dog crate is critical for your dog's comfort, safety, and well-being during travel. The crate should provide enough space for your dog to sit, stand, turn around, and lay down in a natural position. However, it shouldn't be so large that your dog can slide or be tossed around during travel, which can lead to potential injury.
Measure your dog
You need to measure your dog to make sure that the crate you buy will be the right size. Here’s how to do it!

Not sure if the crate will fit? Here's how to check:
1. Depth:
Measure from the back of your rear seats to the end of the trunk floor. If you have a hatchback or SUV, also check where the trunk door starts to slope in.
2. Height:
Measure from the trunk floor to the lowest point of the door, hatch, or ceiling. Watch out for low-hanging edges that could block the crate.

3. Threshold height:
Does your trunk have a raised edge (threshold)? Thule Allax fits thresholds up to 40 mm.

Thule Allax threshold compatible fits thresholds over 40 mm (up to 170 mm for XS, 245 mm for S, M compact, M, L compact).
