Rear leg height
Commonly measured from the floor to the groin/inside rear leg while the dog is standing naturally. The exact manufacturer method may differ.
One important rule
There is no single measurement system for every dog wheelchair. Different manufacturers use different measurements and sizing methods. This page teaches you the basics so you can measure confidently — always use the chosen manufacturer's official sizing guide before ordering.
Before you measure
Keep your dog comfortable
Use a flat, non-slip surface. Let your dog stand naturally if they safely can. Support them gently if needed and never force a painful position.
Measure twice
Keep the tape straight, don't pull it tight into the coat or skin, and repeat each measurement. Photos or a short video can help a fitter see exactly how you measured.

2
Body length
Keep the tape straight rather than following every curve of the dog's back. Check exactly which start and end points your manufacturer asks for.
3
Body width
Measure the comfortable width requested by the wheelchair maker. Too narrow can rub; too wide can affect stability and alignment.
4
Weight
Use a recent accurate weight. Many adjustable wheelchair ranges use weight together with one or more body measurements to choose a frame size.
Watch the correct measuring method
🎥 Use the wheelchair maker's own demonstration
Wheelchair brands do not all measure the same way. Choose the maker first, then open its verified measuring instructions and videos. This avoids copying measurements from the wrong system.
The Hub can add more trusted demonstrations as they are verified, without asking owners to guess which method applies.
Common measuring mistakes
- Measuring while the dog is twisted, crouched or struggling.
- Following the curve of the body when a straight measurement is required.
- Guessing where a measurement starts or ends instead of checking the manufacturer's diagram.
- Ordering from weight alone when the manufacturer asks for additional measurements.
- Assuming measurements for one wheelchair brand automatically match another.
- Forcing an amputee or painful dog into a standard standing position instead of getting fitting advice.
Now choose the correct sizing guide
Once you understand how to measure, use the wheelchair maker's own verified instructions before you buy.
