Pasture, Acreage, Fencing and Turnout Planning
Land and fencing are the largest one-time costs of keeping horses at home. This guide covers how much land a horse needs, how to manage pasture so that it lasts and how to choose and price a fence.
How many acres per horse?
A widely cited rule of thumb is 1.5 to 2 acres of good pasture per horse if it is the main source of feed, more in dry regions and less when you also feed hay. In drought-prone or poor-soil areas a horse can need 5 acres or more. Land that is too small gets grazed to the dirt, turns to mud and weeds and spreads parasites. The Acres per Horse Calculator adjusts the number for your climate, pasture quality, and how much hay you feed. The Pasture Turnout Finder helps you plan the hours of turnout for your situation.
Dry lots and limited turnout
Not every horse should have free access to lush grass. Easy keepers and horses prone to laminitis need limited grazing, a grazing muzzle or a dry lot. A dry lot is a bare paddock where horses get hay instead of grass; give them enough room to move, drainage and shade, and a good surface such as gravel or geotextile fabric with stone dust in the high-traffic areas.
Keeping the pasture healthy
- Rotate horses between paddocks so that grass can recover; leave grass at least 6 to 8 inches tall before regrazing, and take horses off when it is grazed to about 3 to 4 inches.
- Drag or pick up manure to cut parasites. See Deworming Strategy.
- Test the soil and fertilize and lime on that basis.
- Remove poisonous plants such as red maple leaves, ragwort and yew, and check for hazards after storms.
- Keep horses off wet ground and in winter to protect the sod.
Choosing a fence
A good horse fence is visible, strong enough to resist leaning and has no places to catch a hoof or a head. Barbed wire is a common cause of serious injury and is not recommended for horses.
| Fence type | Typical cost | Upkeep | Notes |
|---|---|---|---|
| Wood board | High | Painting, replacing boards | Visible and sturdy; horses may chew |
| Vinyl or PVC rail | Highest | Low | Long life, can shatter under impact |
| Woven wire (no-climb) | Medium | Low to medium | Good for foals and small animals; add a top rail for visibility |
| Electric tape or rope | Low | Needs power and checks | Easy to move; make it visible |
| Pipe or steel | High | Low | Used in paddocks; check for sharp edges |
Most horse fences are 4.5 to 5 feet tall, and taller for stallions or jumpers. Posts are typically spaced 8 to 12 feet apart for board fence, depending on type. The Fence Type Finder narrows the options, and the Horse Fence Cost Calculator estimates materials and total cost from the perimeter, number of rails or strands, gates and posts.
Estimating the perimeter
A square pasture of 1 acre (43,560 square feet) is about 209 feet on a side, so its perimeter is about 835 feet. Larger and more rectangular fields need more fence per acre, and a long thin field uses more than a square one. Convert areas with the Acres to Hectares Converter and lengths with the Feet to Meters Converter when you work with metric plans.
Gates, shelter and water
- Use gates wide enough for equipment, at least 12 feet, and put them in corners away from low spots.
- Provide a run-in shelter or trees that offer protection from wind, sun and rain.
- Make sure there is clean water in every field, and plan for freezing.
- Think about flies and insects; see the Fly Control Finder.
Common mistakes
- Overstocking a small pasture.
- Using wire that a horse cannot see.
- Putting a gate where the ground turns to mud.
- Leaving out the cost of gates, corner posts and labor.
Frequently asked questions
How many acres does one horse need?
Roughly 1.5 to 2 acres of good pasture if it is the main feed, more in dry areas and less when you feed hay and limit turnout. A dry lot can supplement land that is limited.
What is the safest horse fence?
Fences that horses can see and that do not trap a hoof or head, such as wood board, vinyl rail, or woven wire with a top rail. Barbed wire is not recommended.
How long is the perimeter of an acre?
A square acre is about 209 feet on a side, so around 835 feet of fence. Other shapes need more.
