Enter your temperature, tell us about your horse, and we'll suggest a starting blanket weight
Find Your Blanket WeightHow to use this guide. This is a starting point for new horse owners and anyone who wants a refresher on blanketing. If you already know your horse, adjust as needed: not every horse needs the same blanket, and not every horse handles the same weather the same way. As you get to know your horse in different weather, you will learn what he needs, and this guide will help you get there.

Tick any that apply. Clipped, older or underweight, or thin-skinned: go up one weight, and only one, however many you tick. Leave them all blank for an unclipped horse in good condition. Turnout weights already assume your horse is outside.
Horse is clipped
A clipped coat holds less heat, so go up one weight.Senior or underweight
Older horses and horses in poor condition hold heat less well, so go up one weight.Thin-skinned breed
Thoroughbreds, Arabians and fine-boned warmbloods often need one weight heavier.Colder than usual
A cold snap colder than horses in your area are used to, like an Arctic blast. We will suggest a liner.Light Sheet
A light sheet offers wind and rain protection without overheating.
💡 When in doubt, blanket lighter. A horse that is too warm sweats under the blanket, and a damp coat chills him. Check under the blanket at the base of the neck and behind the shoulder: dry and comfortable is right, sweating means go lighter, shivering means go heavier. Adjust as the forecast changes.
All Blanket Weights
Brands name their weights differently, so go by the grams, not the name. Some blankets called “medium” have 150g of fill.
