We have full size guides and charts on our size guide page here However we appreciate size guides can become confusing when there are such a vast array of product choices. We have staff that can help and guide you, please email admin@horzehoods.com or watsap: +44782351047 If for your horse please send breed, height and rug size along with a photo. If for yourself you are welcome to send us your information. All our sizes and conversions are in 'dress size' not 'jeans waist size'. Use your dress size to convert if shopping overseas. You will find all conversions for international sizes on our size guide page lined above.
