Choosing a blanket is not simply a matter of picking the heaviest option on the rack. Your horse's coat, body condition, workload, shelter, weather, and time spent outdoors all affect what protection is appropriate. The right blanket should support comfort without causing sweating, rubs, or restricted movement.
A practical horse blanket guide starts with three decisions: choose the right blanket type for indoor or outdoor use. Match the fill and durability to the weather, and measure carefully for a secure, comfortable fit. Seasonal inspection and proper drying matter just as much as the initial purchase.
Before comparing insulation levels, it helps to understand how sheets, stable blankets, and turnout blankets are designed for different conditions. That distinction gives you a sound foundation for choosing dependable coverage throughout the year.
Types of Horse Blankets: A Complete Guide to Sheet, Stable, and Turnout
Choosing the right blanket starts with the horse's environment. A clean, dry stall calls for different protection than a windy pasture, and not every cold day requires insulation. The three categories below cover most everyday blanketing needs, but the best choice depends on weather, shelter, coat, workload, and your horse's individual condition.
| Type | Fill weight | Waterproof | Best use case |
|---|---|---|---|
| Sheet | Zero fill | Usually no, unless specifically labeled waterproof | Stabling, keeping a clean coat, or adding a light outer layer |
| Stable blanket | Insulated, commonly light to heavy | No | Warmth and coat protection indoors or in a dry, sheltered area |
| Turnout blanket | Insulated, commonly light to heavy | Yes | Outdoor turnout in rain, snow, wind, or wet winter conditions |
Each type serves a distinct purpose. Sheets keep a horse clean in the stall with zero insulation and are not typically waterproof. Stable blankets add warmth indoors but are not built for wet weather. Turnout blankets combine insulation with a waterproof, breathable shell for outdoor protection through rain, snow, and wind.

Blanket Weights and Denier Ratings Explained
Blanket weight and denier describe two different kinds of protection. Fill weight indicates insulation, while denier describes the strength of the outer fabric. Understanding both helps you choose a blanket suited to your horse, weather, and turnout routine.
What do horse blanket weight ratings mean?
Blanket weight is measured in grams of fill, the insulating material inside the blanket. A sheet has 0 grams of fill and provides a light outer layer without meaningful insulation. Lightweight blankets generally contain 100 to 200 grams, medium blankets contain 200 to 300 grams, and heavyweight blankets contain 300 to 400 grams. Extra-heavy blankets contain 400 grams or more and are intended for especially cold conditions. These ranges are summarized in FarmHouse Tack's blanketing guide.
Use the fill rating as a starting point, not an automatic temperature prescription. Your horse's age, body condition, coat, clipping status, shelter, wind, rain, and acclimation all affect the right choice. Horses begin growing a longer, thicker winter coat in July and shed the shorter summer coat in October, so reassess your plan as the season develops. A blanket that works in early fall may not provide enough protection later in winter.
What is the difference between 600D and 1200D horse blankets?
Denier, abbreviated D, measures the thickness and durability of the fabric yarn. A 600D blanket is commonly suited to light or moderate turnout, while 1200D fabric offers greater resistance to wear, snags, and rough daily use. For horses that turn out in demanding conditions or frequently damage blankets, 1680D fabric provides an even more durable option. Denier does not tell you how warm a blanket is, so a 1200D shell can still be lightweight if it has little fill.
Match denier to behavior and environment. A calm horse in a well-managed paddock may do well in 600D. A horse that plays hard, lives with companions, or encounters brush and fencing may benefit from 1200D or 1680D construction.

How to Measure Your Horse for the Perfect Blanket Fit
The best way to determine the correct blanket size is to measure your horse, not rely on height alone. A well-fitted blanket should cover the body without restricting the shoulders, shifting backward, or leaving exposed areas vulnerable to cold and moisture. Use a flexible cloth measuring tape, and have a helper keep your horse standing squarely on level ground.
- Start at the center of the chest. Place the end of the tape at the center of your horse's chest, where the front edges of a blanket would meet. Keep the tape level as you measure along the side of the body.
- Measure to the point of the buttock. Run the tape over the shoulder and along the horse's side to the point of the buttock, the rounded area at the back of the hindquarters. Record the measurement in inches. This number is the starting point for the blanket size, so measure carefully rather than rounding up or down by guesswork.
- Use height only as a rough check. A horse's height in hands can help you compare general size, but it is not a precise sizing method. Two horses of the same height may have very different body lengths, shoulder shapes, barrel widths, or toplines. Let the chest-to-buttock measurement guide your choice, then compare it with the manufacturer's size chart.
- Evaluate the shoulder slope. Look at the shape of the shoulder where the neck meets the body. A sloped shoulder may need a blanket with enough room and shaping to move comfortably, while an upright shoulder may fit better in a different cut. The front of the blanket should lie smoothly without pulling across the withers or pressing into the shoulder.
- Check body width. Decide whether your horse is relatively narrow or wide through the chest and barrel. Width affects how the blanket hangs and whether it slides, gaps, or restricts movement. A blanket that matches length but lacks the right shoulder and chest room may still be a poor fit.
- Inspect the fit after fastening. Allow normal movement, then check that the blanket stays centered and that straps lie flat without twisting. Look beneath the chest, at the withers, behind the shoulders, and around the hindquarters for pressure or rubbing. Proper fit matters because an incorrect size or poorly positioned strap can cause rubs and sores, as noted by Penn State Extension.
Recheck the fit after your horse walks, grazes, and rolls. A blanket that looks correct while standing still may shift during turnout, so regular inspections help you catch problems before a small pressure spot becomes an injury.
Seasonal Blanket Care and Rotation Tips
A blanket works best when it stays clean, dry, secure, and suited to the weather. Build a simple rotation so one blanket can be in use while another is being cleaned, repaired, or fully dried.
Spring: Remove layers gradually and store them correctly
As temperatures rise, remove heavier blankets gradually rather than leaving a horse overheated in winter weight. Once a blanket is no longer needed, brush off hair and debris, then clean it before storage. Follow the manufacturer's care label. For machine-washable blankets, Jeffers recommends cool water no warmer than 85 degrees F, mild soap, and a gentle cycle. Rinse thoroughly and let the blanket dry completely before folding it.
Inspect closures, surcingles, leg straps, stitching, and waterproof areas while the blanket is clean. Repair small tears and replace damaged hardware before next fall. A dry, breathable storage container helps prevent mildew and keeps blankets ready for the next cold season.
Summer: Use lighter protection and store heavy blankets
Many horses need only a fly sheet for summer protection, while heavy winter blankets should remain clean, dry, and out of the way. Do not seal away a blanket that is even slightly damp. Rain, sweat, and washing moisture can create an ideal environment for odor and mildew. If a blanket becomes wet during use, remove it, dry the horse, and air out the blanket before putting it back on.
Fall: Inspect before the first cold weather
Bring stored blankets out early enough to check their fit and condition before the first cold snap. Look for weakened seams, missing fasteners, and clogged or damaged straps. A practical rotation includes a primary turnout blanket, a backup when possible, and a lighter option for milder days. Choose the type and weight for the horse, forecast, activity, and shelter available, not simply the calendar.
Winter: Check the horse and blanket every day
Never put a blanket on a wet horse. Wait until the horse is dry, because moisture trapped beneath the blanket can chill the horse. A wet or muddy coat also loses insulating value, so a blanket should not be treated as a substitute for dryness and grooming. If a horse becomes wet under a blanket from rain or sweating, remove it, dry the horse, and air the blanket before reuse. Penn State Extension recommends removing blankets regularly to inspect for twisted straps, rub marks, and other damage.
On warmer winter days, remove the blanket to prevent sweating. Check the shoulders, withers, chest, belly, and hindquarters for heat, dampness, or rubbed hair. Adjust or change the blanket when conditions change, and keep a clean, dry option available. For selection and seasonal rotation, browse our full selection of horse blankets and sheets.
When to Blanket Your Horse (and When to Skip It)
Blanketing is not a decision made from the thermometer alone. Start with your horse's natural insulation, body condition, age, coat, shelter, and exposure to wind or wet weather. A healthy horse grows a winter coat and carries a layer of fat beneath the skin, two natural defenses that provide meaningful insulation. A woolly horse with a thick coat may retain enough heat that adding a blanket is unnecessary, or even counterproductive.
Use the horse, not one temperature, as your guide
There is no universal temperature at which every horse needs a blanket. As a practical starting point, blanketing deserves serious consideration when a horse has no shelter and the temperature or wind chill falls below 5 degrees F. However, a healthy, acclimated horse with a full coat and access to shelter may need much less help. Karen Waite, MS, PhD, notes that such horses, with a body condition score of at least 4 on the 1-to-9 scale. Might only need a blanket when temperatures drop below 10 degrees F to 0 degrees F. Read the expert guidance from The Horse for that context.
At the other end of the range, 50 degrees F weather usually does not call for a blanket on a healthy. Dry, acclimated horse with shelter and a normal winter coat. A blanket can cause sweating, leaving the horse damp beneath it and vulnerable to chilling later. Watch the horse's comfort and coat condition rather than blanketing automatically whenever the forecast feels cool.
Which horses need extra protection?
- Thin or poorly conditioned horses: A body condition score of 3 or less makes a horse a candidate for blanketing because it has less fat for insulation.
- Young and senior horses: Very young horses and older horses may need extra warmth, especially during prolonged cold or bad weather.
- Clipped horses: A horse body-clipped for showing has lost part of its winter coat and generally needs a blanket suited to the conditions.
- Recently relocated horses: A horse moved from a southern climate needs time to acclimate before facing a northern winter.
Blanketing works best alongside good management. Roughage fermentation in the hindgut creates internal heat, so many owners offer more hay during cold weather. Follow the feeding plan recommended by your veterinarian or equine nutrition professional. Finally, keep reassessing body condition, shelter, wind, precipitation, and behavior as the season changes. If the horse is sweating, shivering, unusually quiet, or losing condition, adjust the plan and seek veterinary advice.
Frequently Asked Questions
What kind of horse blanket does my horse need?
Choose based on your horse's coat, age, health, body condition, shelter, climate, and exposure to wind or precipitation. A waterproof turnout blanket suits outdoor weather, while a stable blanket or sheet is intended for sheltered use. Horses with thick winter coats may not need a blanket, but clipped, elderly, young, underweight, or unacclimated horses often need additional protection. Reassess the choice as conditions change.
At what temperature should I blanket my horse?
There is no single temperature that applies to every horse. Consider wind, rain, shelter, coat, and individual health rather than relying on the thermometer alone. Blanketing may be necessary when a horse has no shelter and temperatures or wind chill fall below 5 degrees F, according to Penn State Extension. A horse that is sweating under a blanket is too warm and needs prompt attention.
How do I determine the correct horse blanket size?
Measure in inches from the center of the chest to the point of the buttock, then compare that measurement with the manufacturer's size chart. Height in hands is only a rough reference. Check that the blanket allows comfortable movement without pulling across the chest, shifting, or leaving gaps. Proper fit matters because an incorrect size or poorly adjusted strap can cause rubs and sores, as Penn State Extension notes.
When should I change a horse blanket?
Change it when temperature, precipitation, turnout conditions, or your horse's comfort level changes. Remove the blanket on warm days to prevent sweating, then dry and air both the horse and blanket before replacing it. If the blanket becomes wet, take it off, dry the horse, and air out the blanket. For continuously blanketed horses, inspect regularly for twisted straps, damage, and rub marks.
Can horse blankets be washed?
Yes. Follow the care label first, remove excess hair and dirt, and use a mild soap on a gentle, cool wash cycle when the manufacturer permits machine washing. Let the blanket dry completely before storing or putting it back on your horse. A clean, fully dry blanket helps preserve its materials and prevents trapped moisture from chilling the horse.
