Finding a saddle where the shape of the panels and tree match the shape of your horse’s back, is not as simple as choosing narrow, medium or wide.
One of the problems that you can encounter is “bridging.” This is when the front and back of the saddle make contact with the horse’s back, but there is a gap below where the rider sits. This means that the pressure is concentrated at the front and the back, and not spread evenly across the horse’s back. In other words, it’s a recipe for a sore back.
How can you tell if your saddle is bridging? If you do a visual inspection of the saddle and look down the pommel area you will see daylight under the panels. However there are other ways to check for bridging.
Reading sweat/dirt marks on your saddle pad.

Thermographic imaging
Thermographic images show heat. In the context of saddle fitting, heat correlates with pressure.

A few caveats about bridging
Two things to keep in mind about evaluating bridging in saddles is that
- Sometimes sweat patterns that indicate bridging may be caused by a horse that is hollowing its back. That could be caused by saddle fit but it may also mean that the horse needs to be encouraged to engage its abdominal muscles and raise its back, and
- A saddle that might bridge slightly when a horse is standing still may fit fine when the horse is in motion and it raises its back.
So, if you suspect your saddle is bridging, call a saddle fitter!
