Duck Run Size Calculator
Enter your duck count, breed size, and yard conditions to estimate outdoor duck run square footage, practical run dimensions, fence length, roof netting, splash-zone space, and bedding or drainage material for a cleaner setup.
For standard backyard ducks, start with about 15 square feet of outdoor run space per duck. Small ducks can often start around 10 square feet each, while heavy breeds, muddy yards, and confined flocks should be planned larger.
A six-duck flock can start around a 9 ft × 10 ft run. Four ducks might use a 6 ft × 10 ft run, while ten ducks often need about 10 ft × 15 ft before adding extra space for water tubs, shade, feeders, and muddy-season rotation.
Ducks need water deep enough to clean their bills, and that water often creates wet soil nearby. Put drinking water and tubs on gravel, hardware cloth, pavers, or another washable drainage zone, and cover the run against local predators.
Build larger than the calculator's baseline if ducks stay in the run most days, your yard has clay soil, the flock includes heavy breeds, or you want grass to recover. Extra space is the easiest upgrade to appreciate later.

Use about 15 square feet per standard duck as a practical starting point. Add more for large breeds, muddy soil, winter confinement, or if ducks spend most daylight hours in the run.
For 4 standard ducks, start around 60 square feet, such as 6 ft by 10 ft. If the run has a water tub or poor drainage, make it larger.
For 6 standard ducks, start around 90 square feet, such as 9 ft by 10 ft. A larger run will stay cleaner and give the ducks more room to forage.
A 4 ft tall covered run can work for ducks, but a 6 ft or taller walk-in run is easier for people to clean and maintain. Predator protection matters more than height alone.
Some flocks free-range during supervised daylight, but a secure run is still useful for predators, bad weather, travel days, garden protection, and times when you need the ducks contained.
In many yards, yes. Netting, wire, or a roof helps protect ducks from hawks, raccoons, foxes, dogs, and other predators. Use materials appropriate for your local predator pressure.
