i dunno, some saddles are pretty obviously too narrow or such. Eg. Gullet should be at least 3-4" wide and bars/forks should make something like an 80-90 degree angle. Many saddles, esp older types, seem more suited to the width of a greyhound, not any kind of horse!
If OP were to take some easily bendable wire and lay it across the rear of her withers and down over the horse's shoulder and if she took another piece of wire to run along the back beside the spine from wither to lumbar, then she would know how wide & what shape the horse's shoulders & back are, and laying this wire against the saddle should give an idea how right or wrong it is for the horse.
OP there's also a mob Balance International, who have a lot of great saddle fitting info on their site.
Once you ensure you have a comfortable, well fitting saddle for the horse, you still need to make sure it's positioned properly and check it's fit every few months or so, as horses & saddles change shape over time.
