Horse rugs come in an overwhelming range of types, weights and sizes. Turnout rugs, stable rugs, fly sheets, coolers, day sheets and rain sheets all have different jobs, and choosing the wrong one can leave your horse too hot, too cold or uncomfortable.
South Africa's climate adds another layer to the decision. A horse on the Highveld may face frosty winter nights, while a horse in the Western Cape deals with cold, wet winters, and a horse in KwaZulu-Natal may need more protection from flies and humidity than from cold.
This guide explains the main types of rug, what fill weights mean, how to measure your horse and how to check that a rug fits.
Does Your Horse Need a Rug?
Horses are well adapted to regulating their own temperature. A healthy horse with a natural winter coat, access to shelter and plenty of forage often copes well without a rug in much of South Africa.
A rug may be helpful if your horse:
- Has been clipped
- Is older, underweight or struggles to hold condition
- Has a fine coat, as many Thoroughbreds do
- Has no access to shelter from wind and rain
- Is exposed to cold, wet and windy weather at the same time
- Needs protection from flies, midges or the sun
Over-rugging is a common mistake. A horse that is too warm under a rug can sweat, become uncomfortable and lose condition. To check whether your horse is comfortable, slide your hand under the rug behind the withers. The skin should feel warm and dry, not hot and damp or cold.
Types of Horse Rugs
| Rug type | What it is for |
|---|---|
| Turnout rug | Waterproof, breathable rug for horses living out or turned out in the paddock |
| Rain sheet | Lightweight turnout rug with no fill, to keep a horse dry without adding warmth |
| Stable rug | Warm rug for use indoors; not waterproof |
| Fly sheet | Lightweight mesh rug that protects against flies, midges and sun |
| Cooler | Wicking rug that helps a sweaty or wet horse dry off after exercise, washing or travel |
| Day sheet | Light cotton or fleece sheet used to keep a horse clean, often at shows |
Many rugs can be paired with a matching neck cover for extra warmth or protection.
Understanding Rug Weights
The warmth of a rug is usually described by its fill weight, measured in grams. The higher the number, the warmer the rug.
| Weight | Typical fill | When it is used |
|---|---|---|
| No fill | 0 g | Rain protection without warmth |
| Lightweight | Up to about 100 g | Cool, wet or windy weather and chilly nights |
| Mediumweight | About 150–250 g | Cold weather and clipped horses |
| Heavyweight | About 300 g or more | Very cold conditions and fully clipped horses |
Exact ranges vary between manufacturers. In much of South Africa, lightweight and mediumweight rugs are the most useful. Heavyweight rugs are usually only needed for clipped horses in the coldest areas, such as on frosty Highveld nights.
You may also see the outer fabric described in denier, such as 600D or 1200D. Denier refers to the thickness of the fibres, and a higher denier generally means a tougher, more tear-resistant fabric. If your horse is rough on rugs or shares a paddock with playful companions, a higher-denier turnout rug may last longer.
How to Measure Your Horse for a Rug
Rug sizes are based on the length of your horse. To measure:
- Stand your horse square on level ground.
- Use a soft tape measure.
- Start at the centre of the chest.
- Run the tape along the side of the horse, over the widest part of the shoulder.
- Finish at the point of the buttock, at the back of the hindquarters.
Many rugs are sized in feet and inches, while others are sized in centimetres. Use this table to convert your measurement:
| Rug size | Approximate length | Often fits |
|---|---|---|
| 4'6"–5'0" | 137–152 cm | Small ponies |
| 5'3"–5'9" | 160–175 cm | Larger ponies and cobs |
| 6'0"–6'3" | 183–191 cm | Small to average horses |
| 6'6"–6'9" | 198–206 cm | Average to large horses |
| 7'0" and up | 213 cm and up | Large horses |
Horses of the same height can need different rug sizes, depending on their build, so always measure rather than guessing from height. Some brands, particularly American ones, measure and size their rugs differently, so check the manufacturer's size chart before you buy.
If your horse falls between two sizes, the cut of the rug matters. Some brands are more generous through the shoulder, while others suit finer horses.
How to Check That a Rug Fits
A well-fitting rug should:
- Sit just in front of the withers without pressing on them
- Allow you to slide your hand flat under the rug at the withers and shoulders
- Fasten across the chest without pulling tight or gaping
- Reach the top of the tail, covering the hindquarters
- Have belly straps that cross under the belly with about a hand's width of space
- Have leg straps, if fitted, linked through each other to prevent rubbing
- Allow the horse to move, graze and lie down comfortably
Watch for rubbing on the shoulders, chest and withers, particularly with a new rug. A rug that is too small can rub and restrict movement, while one that is too big can slip and become a safety hazard.
Caring for Your Rugs
- Remove rugs daily to check your horse's body and skin for rubs, injuries and changes in condition.
- Repair small tears promptly before they become large ones.
- Clean rugs regularly, following the manufacturer's washing instructions.
- Reproof turnout rugs when they start to lose their waterproofing.
- Store clean, dry rugs in a sealed bag or container to protect them from rodents and insects.
Buying Second-Hand Rugs
Second-hand rugs can be excellent value, especially if your horse needs several types. Before buying, check:
- The size, by measuring the rug rather than relying on the label
- The condition of straps, buckles and clips
- For turnout rugs, whether the outer is still waterproof
- For tears, worn patches and damaged lining
Always wash a second-hand rug thoroughly before putting it on your horse to reduce the risk of spreading skin conditions.
Frequently Asked Questions
Should I rug my horse at night in winter?
It depends on your horse, its coat, whether it is clipped, its shelter and your local conditions. Many unclipped horses cope well without a rug, while clipped or older horses may benefit from one on cold nights. Check your horse regularly and adjust rather than rugging by habit.
What size rug does a 16-hand horse wear?
Many 16-hand horses wear a rug of around 6'3" to 6'6", but the right size depends on the horse's build. Always measure your horse before buying.
Can a stable rug be used outside?
No. Stable rugs are not waterproof and can become wet, heavy and cold if used outside in the rain. Use a turnout rug for horses that are turned out.
Do fly sheets help protect against African horse sickness?
Fly sheets and masks can reduce your horse's exposure to midges, which spread AHS, but they are not a substitute for vaccination. Read our guide to African horse sickness for more on prevention.
