Measuring Your Horse For A Blanket
Most blankets are measured in inches with average sizes measuring 69" to 84". To find your horses size, take a measuring tape and start at the center of your horses chest and run it down his or her side to the point of the buttocks (where the cheek meets the tail). Be sure to include the widest part of the shoulder, and keep the tape level and taut.
Keep in mind that every horse is different and that this is a guide only.
