A properly fitted rug is essential for your horse's comfort and wellbeing. Too small and it will rub and restrict movement; too large and it will slip, twist, and potentially cause injury. This comprehensive guide will teach you how to measure your horse accurately and choose the perfect rug size every time.
Why Rug Fit Matters
An ill-fitting rug can cause serious problems:
Too Small
- Rubs on shoulders, withers, and chest
- Restricts movement and causes discomfort
- Doesn't provide adequate coverage
- Can cause pressure sores and hair loss
- Tears more easily due to strain
Too Large
- Slips and twists, potentially tangling legs
- Excess fabric can cause tripping
- Doesn't stay in correct position
- Allows cold air and rain underneath
- Can cause panic if horse gets caught
How to Measure Your Horse
What You'll Need
- Soft measuring tape (fabric, not metal)
- Helper (makes measuring easier)
- Pen and paper to record measurements
- Your horse standing square on level ground
The Standard Measurement Method
Step 1: Position Your Horse
- Stand horse square on level ground
- Ensure they're standing naturally
- Head should be in normal position
Step 2: Find the Starting Point
- Locate the center of the chest
- Where the base of the neck meets the chest
- This is where the rug will sit at the front
Step 3: Measure Along the Side
- Place tape at center of chest
- Run tape along the horse's side
- Follow the natural line of the body
- Measure to the point of the buttock
- Keep tape parallel to the ground
- Don't pull tight—allow natural drape
Step 4: Record the Measurement
- Note measurement in inches or centimeters
- Round to nearest inch/3cm
- This is your rug size
