Equestrian Advanced Calculators
Configure Parameters
Take a flexible piece of copper wire, shape it directly over the horse's withers (approx 2 inches behind the shoulder blade), trace the contour onto a sheet of paper, and measure the internal angle using a standard protractor.
Standard medium tree. Suitable for most Quarter horses, Cob types, and thoroughbred crosses.
Horse Care Tips
- Always confirm saddle clearance with a professional saddle fitter.
- Check for a minimum of 2-3 fingers clearance over the spine/withers when rider is in saddle.
- Saddle fits will change as the horse gains/loses muscle through work seasons.
