Winter Horse Blanket Guide + Horse Blanket Weight Chart

Winter Horse Blanket Basics (So the “Weight” Part Makes Sense)

When people say “winter blanket weight,” they’re talking about the amount of fill (insulation) inside the blanket—usually measured in grams (g). More grams = more trapped air = more warmth. That’s different from:

• •Denier (D): The toughness of the outer fabric (e.g., 600D vs 1200D). Higher denier usually means more tear resistance.
• •Waterproofing/breathability: How well the outer shell blocks rain/snow while letting sweat vapor escape.
• •Neck style and coverage: A blanket with a neck cover can feel warmer than the same fill weight without one.

Also remember: horses regulate temperature best when they can raise their hair coat (piloerection). A blanket flattens the coat—so the horse may actually need more insulation than you’d think on cold days if they’re blanketed continuously.

What changes your horse’s blanket needs (more than the thermometer)

You’ll make better choices if you evaluate these factors first:

• •Body condition: Thin horses need more warmth; overweight horses often need less.
• •Age/health: Seniors, PPID (Cushing’s), PSSM, hard keepers, and horses with limited turnout often need extra.
• •Coat: A trace clip vs full body clip is a huge swing in warmth needs.
• •Shelter and wind exposure: Wind is the blanket “multiplier.” A calm 25°F can feel easier than a windy 35°F.
• •Moisture: Cold + wet is where under-blanketing gets risky fast.
• •Temperament and movement: A horse pacing the fence line runs warmer than one standing at a hay net.

Real scenario

A full-clipped Thoroughbred in a windy paddock at 30°F needs a very different setup than a fuzzy Icelandic in the same weather. Breed and coat style matter—sometimes more than the temperature.

Horse Blanket Weight Chart (Fill in Grams) + How to Actually Use It

Here’s a practical horse blanket weight chart you can use as a starting point. It assumes an average adult horse in decent weight, with turnout, and access to some shelter. Treat it like a baseline—then adjust in the next section.

Horse blanket weight chart (starting point)

0g (Sheet / Rain Sheet)

• •Approx temp range: 50–65°F (10–18°C) with rain/wind, or mild cool nights
• •Best for: keeping horse dry, cutting wind, keeping coat clean

50–100g (Lightweight)

• •Approx temp range: 40–55°F (4–13°C)
• •Best for: horses that run warm, mild climates, unclipped horses in wind/rain

150–200g (Medium-Light)

• •Approx temp range: 30–45°F (-1–7°C)
• •Best for: average horses, partial clips, typical fall-to-early-winter conditions

250–300g (Medium)

• •Approx temp range: 20–35°F (-6–2°C)
• •Best for: many blanketed horses in true winter, moderate wind

350–400g (Heavy)

• •Approx temp range: 10–25°F (-12–-4°C)
• •Best for: seniors, hard keepers, clipped horses, windy turnout

450–500g+ (Extra Heavy)

• •Approx temp range: below 10°F (-12°C) or extreme windchill
• •Best for: fully clipped, thin, or medically fragile horses in harsh conditions

Pro-tip: If your barn uses “light/medium/heavy” labels, ask for the actual fill grams. “Medium” can mean 200g at one brand and 300g at another.

Adjust the chart fast: the 3-question check

Use the chart, then ask:

1. Is my horse clipped?

• •Trace clip: add ~+100g
• •Full body clip: add ~+200g (sometimes more)

1. Is it wet/windy?

• •Add ~+50–150g equivalent (or prioritize a better waterproof, windproof turnout)

1. Is my horse a hard keeper/senior?

• •Add ~+100g or use layering for flexibility

Breed + Body Type Examples (Because a Chart Isn’t the Whole Story)

Different breeds and “types” manage cold differently. Here are realistic examples you can map to your horse.

Thoroughbred (TB) / TB-cross: often needs more help

TBs frequently have thinner skin, less natural insulation, and can be prone to dropping weight in winter.

• •Example: 1,100 lb TB gelding, trace clip, 25°F windy turnout
• •Likely setup: 250–300g turnout + optional 100–200g liner if he chills
• •Watch for: weight loss, tense posture, “cold back” under the blanket

Quarter Horse: many run warm, but individuals vary

Stock breeds often do well with moderate blanketing unless clipped or older.

• •Example: 1,200 lb QH mare, unclipped, 35°F with rain
• •Likely setup: 0g rain sheet or 100g turnout depending on wind/shelter
• •Watch for: sweating under heavier blankets during sunny daytime warm-ups

Draft breeds: blanket lightly (and check often)

Drafts can overheat surprisingly fast because they generate heat and often have dense coats.

• •Example: Percheron cross, thick coat, 28°F calm, good shelter
• •Likely setup: no blanket or 0g if wet conditions
• •Watch for: sweating at the shoulders and behind elbows—classic over-blanketing signs

Arabs: can be sensitive to cold + weight maintenance

Some Arabs run hot, but many are leaner and can struggle to hold weight.

• •Example: 900–1,000 lb Arab, senior, mild PPID, 20°F nights
• •Likely setup: 300–400g turnout; consider layering to avoid frequent blanket swaps

Ponies (Welsh, Shetland, etc.): usually need less, but beware rain + wind

Ponies are built to survive weather. Over-blanketing can be a problem.

• •Example: 12.2h Welsh pony, unclipped, 40°F rainy and windy
• •Likely setup: 0g waterproof sheet (to keep hair loft functional and avoid soaking)

Specialty: Friesians, Warmbloods, gaited breeds

• •Friesians: can sweat under too much blanket; also prone to skin issues—breathability matters.
• •Warmbloods: often fine with medium weights unless clipped.
• •Icelandics/Fjords: usually minimal blanketing unless clipped or in wet wind.

Step-by-Step: How to Choose the Right Blanket Weight (Without Guessing)

This is the method I’d use if I were helping a client make a barn-ready blanket plan.

Step 1: Start with your barn’s “worst typical day”

Not the average day—the day where horses most often get uncomfortable:

• •Cold rain + wind
• •Sudden temperature drop after a warm week
• •Wet snow that soaks a coat

Pick a baseline turnout that can handle that day (usually a waterproof turnout).

Step 2: Decide your “baseline turnout” weight

Most owners do well with one of these strategies:

• •Strategy A (minimal blankets):

1 waterproof turnout + 1 heavier turnout Good for barns that can change blankets daily.

• •Strategy B (layering):

1 waterproof turnout shell (0g) + liners (100g/200g/300g) Best for changing conditions and reducing bulk.

• •Strategy C (set it and monitor):

1 medium turnout (200–300g) used most winter Works in moderate climates, but riskier in temperature swings.

Step 3: Add a stable blanket only if you truly need it

A stable blanket is not waterproof and is meant for indoors. Use it if:

• •Your horse is clipped and stalls overnight
• •Your barn is drafty/cold
• •You need extra warmth without extra waterproof bulk

Step 4: Confirm with the “under-the-blanket check”

Twice daily for a week when winter starts, put your hand:

• •Behind the elbow (sweat check)
• •At the withers (core warmth)
• •Under the shoulder (rub and heat check)

What you want:

• •Warm skin, dry, relaxed horse

What you don’t want:

• •Dampness, hot spots, or a horse that feels cool at the core

Pro-tip: A horse can feel warm at the neck but still be chilled at the core. Always check at the withers/chest area, not just the shoulder.

Blanket Fit Guide: Getting the Size, Shoulder Room, and Coverage Right

A perfect weight blanket still fails if the fit is wrong. Poor fit causes rubs, restricts movement, and can even become unsafe.

How to measure blanket size (quick + accurate)

You’ll need a soft tape measure.

1. Stand your horse square.
2. Measure from the center of the chest (where the blanket front sits).
3. Run the tape along the side to the point of the buttock (where the blanket ends).
4. The measurement in inches is your blanket size (rounded to the nearest even number).

Common sizes:

• •Ponies: 60–72
• •Average horses: 72–81
• •Big-bodied: 81–87+

Fit checkpoints (do these before turning out)

• •Front closure: Should sit at the chest without gaping; you should fit a hand in comfortably.
• •Shoulder freedom: Horse should be able to graze and walk without the blanket pulling tight across the point of shoulder.
• •Withers clearance: No pressure on withers; a withers pad can help but shouldn’t be a crutch for the wrong size.
• •Length: Ends around the top of the tail, not hanging like a skirt.
• •Surcingles: Crossed, not twisted; you should fit a flat hand between strap and belly.
• •Leg straps: Adjust so the horse can move freely but not step through.

High-wither horses and narrow chests (TBs, some Arabs)

Look for:

• •High-wither cut
• •Shoulder gussets
• •Adjustable front closures (V-front or similar designs)

Broad-chested horses (QHs, drafts, some warmbloods)

Look for:

• •Roomier chest design
• •Strong front hardware
• •Belly coverage that doesn’t pinch

Common fit mistakes (that cause most rubs)

• •Too tight at the chest → shoulder rubs and restricted stride
• •Too long → blanket shifts and twists
• •Too loose in front → shifting + wither pressure
• •Neck cover mismatch → gaps that funnel rain down the shoulders

Pro-tip: If you see consistent shoulder rubs, don’t just add padding—try a different cut (gusset/V-front/high-wither) first.

Layering Like a Pro: Warmth, Flexibility, and Fewer Blanket Changes

Layering isn’t just “more blankets.” It’s a system to adapt to changing temps while keeping the horse dry and comfortable.

Why layering works

• •Traps air in multiple layers (similar to human winter clothing)
• •Lets you adjust warmth without swapping the entire turnout
• •Keeps the waterproof shell as the outermost layer

The safest layering order (most situations)

1. Base layer (optional): wicking sheet or thin stable sheet (useful for clipped horses)
2. Insulation layer: liner or stable blanket (100–300g)
3. Outer shell: waterproof turnout (often 0g)

Avoid putting a stable blanket on the outside—if it gets wet, it becomes heavy and cold.

Step-by-step layering decisions (simple rule set)

Use your baseline turnout shell and adjust insulation:

1. If it’s wet/windy: prioritize waterproof shell first.
2. If horse is dry but cold: add +100–200g liner.
3. If horse is sweaty: remove insulation or switch to a lighter liner.
4. If temps swing day/night: use a liner you can remove midday.

Example layering plans

Plan for a clipped TB in a variable climate

• •40–50°F: 0g shell or 100g turnout
• •30–40°F: 0g shell + 200g liner
• •20–30°F: 0g shell + 300g liner (or 300g turnout)
• •Below 20°F: 0g shell + 300g liner + neck cover (if needed)

Plan for an unclipped QH with good shelter

• •40–55°F rain: 0g shell
• •30–40°F: 100–200g turnout
• •20–30°F windy: 250–300g turnout (or add liner)

Pro-tip: Liners reduce “blanket pile-up” at the chest compared to stacking multiple full blankets with bulky front closures.

Turnout vs Stable Blankets, Denier, and Waterproofing (What to Buy and Why)

Blankets fail most often because owners buy the wrong type, not the wrong grams.

Turnout blankets

Use for outdoor wear. Look for:

• •Waterproof + breathable outer shell
• •Higher denier if your horse plays hard or lives with blanket-shredders
• •Good shoulder design (gussets, V-front)

Best for: pasture turnout, wet snow, rain, wind

Stable blankets

Not waterproof. Designed for indoor warmth without overheating.

Best for: stalls, dry cold barns, layering under a turnout shell

Sheets

• •Rain sheet (turnout sheet): waterproof, usually 0g
• •Stable sheet: non-waterproof, thin
• •Cooler: wicks moisture after work/bathing (not for turnout unless designed for it)

Denier recommendations (quick guide)

• •600D: fine for gentle horses or supervised turnout
• •1000D–1200D: good “daily driver” toughness for many barns
• •1680D: for rough turnout, big herds, or chronic blanket damage

Waterproofing reality check

“Waterproof” isn’t forever. It’s a combination of:

• •Coating/membrane integrity
• •Seams (taped vs not)
• •DWR (durable water repellent) finish maintenance

If your horse comes in damp across the back after rain, that blanket is no longer doing its job.

Product Recommendations + Smart Comparisons (Budget to Premium)

I’m not in your barn, so think of these as “what to look for” recommendations—plus a few common, reliable picks many owners use.

1) Best versatile system: turnout shell + liners

Why: Most adaptable, usually cost-effective long-term.

Look for:

• •0g waterproof turnout with liner loops/attachments
• •100g and 200g liners (add 300g if you’re in a cold region or have clipped horses)

Good for:

• •Owners dealing with big temperature swings
• •Clipped horses
• •Barns where you can adjust layers

2) Best for minimal hassle: one medium turnout (200–300g)

Why: Simplest for moderate winters.

Look for:

• •Strong hardware, good shoulder design
• •Solid waterproof rating
• •Optional neck cover compatibility

Trade-off:

• •Less adaptable on warm days and cold snaps

3) Best for tough turnout: high-denier turnout (1200D+)

Why: If your horse lives with playful buddies, fabric matters.

Look for:

• •Reinforced shoulders
• •Quality leg straps and surcingles
• •Good warranty or proven durability

4) Best for sensitive skin/rub-prone horses

Look for:

• •Smooth lining (nylon/polyester)
• •Shoulder gussets / V-front
• •Optional shoulder guard (lycra) for chronic rubbers

Quick comparisons (what matters most)

• •Liners vs stacking blankets: liners reduce bulk and pressure points
• •Neck cover vs no neck: neck adds warmth, but can increase sweating; great for clipped horses in wind
• •Cheap waterproof vs quality waterproof: leaks cost more in vet bills and lost condition than a better turnout does

Pro-tip: If you can only splurge on one feature, choose a reliably waterproof turnout with a cut that fits your horse’s shoulder and withers.

Common Mistakes (And How to Fix Them Fast)

Mistake 1: Over-blanketing because “it’s winter”

Overheating is common and can lead to sweating, chills later, and skin funk.

Signs:

• •Damp shoulders/chest
• •Restlessness, drinking less
• •Hot ears + sweaty behind elbows

Fix:

• •Drop one layer or 100–200g
• •Check mid-day temps (sun can heat blankets fast)

Mistake 2: Under-blanketing a clipped or thin horse

Signs:

• •Shivering
• •Tight tucked posture, reluctant to move
• •Weight loss despite good feed

Fix:

• •Add insulation (liner or heavier turnout)
• •Prioritize windproof + waterproof outer layer

Mistake 3: Bad fit “because they’ll grow into it”

They won’t. They’ll just get rubs.

Fix:

• •Re-measure
• •Switch cuts (high-wither, gussets, V-front)
• •Use a shoulder guard while you correct fit, not instead of it

Mistake 4: Leaving wet blankets on

Wet + cold is the perfect setup for chilling and skin issues.

Fix:

• •Have a backup turnout or at least a dry sheet
• •Rotate and dry properly

Mistake 5: Ignoring daily checks

Even the best blanket can slip, tear, or create pressure points.

Fix:

• •Quick AM/PM hands-on check at withers, chest, behind elbows

Pro-tip: Blanket problems are easier to fix on day 2 than day 20—catch rubs early before they become sores.

Expert Tips: Comfort Checks, Skin Health, and When to Change Your Plan

The 60-second blanket comfort exam

Do this when you bring your horse in or before you turn out:

1. Hand under the blanket at the withers: warm, dry?
2. Check behind elbows: dampness = too warm or poor breathability/fit
3. Look at shoulders: hair broken or flat spots?
4. Check blanket position: centered, not pulling back?
5. Feel ears and limbs: cold legs are normal; cold core isn’t

Skin and coat health in blanket season

Blankets create a microclimate—moisture + friction = skin trouble.

Reduce risk by:

• •Keeping horse clean and dry before blanketing
• •Using breathable materials
• •Washing blankets and checking for detergent residue (itching)
• •Treating rain rot early (don’t trap moisture)

Special situations

Hard keepers

• •Often do better with a consistent baseline plus layering
• •Weigh tape or body condition score every 2–3 weeks in winter

Seniors

• •May have poorer circulation and muscle mass
• •Often benefit from heavier weights sooner, especially at night

PPID (Cushing’s)

• •Coat can be abnormal; sweating patterns can be misleading
• •Work with your vet on clipping and blanket strategy

Horses in work

• •A sweaty horse under a turnout is a fast track to chills
• •Use coolers correctly, then switch to stable/turnout layers when dry

Putting It All Together: Sample Blanket Setups for Real Barn Life

If you want a practical “shopping + planning” blueprint, here are setups that cover most winter needs.

Setup A: The versatile layering kit (best for most owners)

• •1 waterproof 0g turnout shell (liner compatible)
• •1 100g liner
• •1 200g liner
• •Optional: neck cover, especially for clipped horses
• •Optional: lightweight stable sheet for indoor use

Best for:

• •Temperature swings
• •Clipped horses
• •Owners who like control without owning 6 turnouts

Setup B: The two-turnout kit (simple, reliable)

• •1 waterproof 100–200g turnout
• •1 waterproof 350–400g turnout

Best for:

• •Barns where staff changes blankets based on weather
• •Horses that don’t need fine-tuned adjustments

Setup C: Minimalist (mild winter, good shelter)

• •1 waterproof 0g rain sheet
• •Optional: 1 200g turnout for cold snaps

Best for:

• •Unclipped easy keepers
• •Ponies (often)

Quick Reference: What to Do When Your Horse Is Too Hot or Too Cold

If your horse is too hot

• •Remove one layer or drop 100–200g
• •Improve breathability (better turnout shell)
• •Consider removing neck cover
• •Check fit—tight chest/shoulder friction can make sweating worse

If your horse is too cold

• •Add a liner (start with +100–200g)
• •Improve wind protection (better shell, neck cover)
• •Increase forage availability (hay is internal heat)
• •Evaluate health/weight (thin horses lose heat faster)

Pro-tip: Hay is heat. If your horse is cold and safe to eat more forage, increasing hay is often more effective (and healthier) than simply piling on blankets.
