When ordering your Equipedic Saddle Pad please be aware of the advertised "Length" VS  "Needed for Saddle Length"  The example at the right is for the standard Equipedic western pad which is advertised as 30" Length.  Thats true as the overall maximum length of the pad is 30"  BUT  you want to know how long it is where your saddle sits.  So that would be 28 at the spine tapering to  29" at the base of the foam insert making the maximum length saddle on this pad no more than 25-26 inches.

For the Endurance pad which is advertised as having a 28" Length, the actual length at the spine is 26"  tapering to 28" at the base of the foam insert in the pad. So in order to get your needed minimum of 1" pad sitting front and back of the saddle, the maximum length saddle on this pad would be 24".
