Please reference the following measurements for general sizing guidance. As each product is hand-made, please allow up to an inch tolerance. If your horse is between sizes we recommend that you go down to the nearest size for the best fit. All Bobby’s bridles are very adjustable. If you have a hard-to-fit horse, Bobby is proud to offer customization to any bridle for a small up-charge. Please call us if you have any questions about getting the perfect fit.
