Tree Sizes

There are 2 sizes

Standard tree: Fits most horses with a distance of 9" or less between the center of each longissimus dorsi muscle. Great for horse with A-frame shaped backs and/or normal to high withers. 

Shire tree: Fits most horses with a distance greater than 9" between the center of each longissimus dorsi muscle and great for horses with mutton withers and very flat backs

Why does this matter?

A metal stirrup bar is attached to the layers of leather that make up the tree. If the stirrup bar is too narrow for the horses back, it can cause pinching & will be impossible to adjust the saddle to a level and balanced position as the saddle will be uphill no matter how you have the panels adjusted.
