Pad size is a bit of a hot topic among those who make pulled wool saddle pads. Some offer any size or shape, while others (including myself) are wary of making pads that are too large. This is because oversized pads can wear out prematurely or even rip around the cinch area from repeated friction. Even a 32 x 32 inch pad can wear out prematurely. For this reason, I suggest 30 x 30 inches as a base size and 30 x 32 for those with long skirted saddles. 30 x 32 is also a good option for those who want to see more of the pad design while riding without compromising the lifespan of their pad. To understand why oversized pads can be problematic, we can look at the history of these pads as well as what other pads are available in modern times.
These saddle pads originated decades ago and were a staple among working cowboys and ranchers across the American west. Wool was chosen as it is thermoregulating, breathable, and provides great shock absorption during long rides. Often times the wool was latched onto a coffee sack, canvas bag, or whatever material might be available at the time. Historically, these pads were meant to be approximately the same length of the saddle skirt or an inch or so longer. This was largely to prevent pine needles, burs, or other materials from getting stuck in the wool during rides in rough terrain and also in part to cut down on weight and unnecessary bulk and weight.
For a modern saddle pad, 30 x 30 is actually a very standard size. For instance, a standard size 5 Star pad is 30 x 28, a standard size Impact Gel pad is 30" by 28-30", and a generic Weaver felt pad comes in 27 x 27, 30 x 30, or 31 x 32. These pads also have wear leathers to protect the pad from friction, sweat, and rubbing from the fender and cinch. It is not possible to attach wear leathers to a pulled wool saddle pad (a couple pad makers have tried, it just doesn't work), therefore it is even more important to factor in size in order to prevent premature wear to your pad.
