Good cattle pen design comes down to flow. Cattle come in from pasture, stand in a holding pen sized for the herd, move down a lane into a crowding area built for small groups, go single file to the chute, and leave into a sorting pen without anyone climbing a fence. Size holding pens at about 20 square feet per mature cow (34 for a pair), crowding pens at about 12 square feet per cow, and hang the gates in the corners.
The details are where pens go wrong: a crowding tub loaded with 20 head when it should hold 8, a bud box used as a holding pen, a chute pointed into the evening sun. None cost more to get right on paper, and all of them cost you every working day once the pipe is welded.
Below is the layout the way a builder walks it, with the sizes the extension services publish. If you want someone to walk your ground and draw the pens on the dirt with you, call (254) 870-8898 for a free on-site estimate.
The six parts of a working facility
Ohio State’s Beef Quality Assurance handling and facilities bulletin splits every working facility into six sections: holding pens, an alley from the pens to the working area, a crowding pen or tub, a single-file working alley, the headgate or squeeze chute, and a loading area.
A small setup can combine some of these. On 40 acres with 15 cows, the holding pen might double as the sorting pen. But each job still happens somewhere, and a pen that feels awkward to work usually left one of the six out.
Where to put the pens
The Ohio State bulletin recommends a high, well-drained site with slopes under about 10 degrees (roughly two inches of fall per foot), close to water and power, and not right beside a house because of dust, flies and noise. It also points out that the easiest place to pen cattle is a pasture corner, ideally where several pastures meet. The pasture fence next to the corral takes extra pressure at the gather, so it wants bigger posts and more bracing than the rest of the line.
Around Waco, drainage is the one people underrate. Blackland clay holds water, turns to grease, and shrinks and swells enough to move posts. A pen set in the low corner because it was handy will be a mud hole every wet spring, and cattle will not move well over footing they do not trust. Take the high ground even if it adds a hundred feet of lane. If flat clay is all you have, plan dirt work and base under the tub, alley and chute before any pipe goes up. Ohio State suggests rough concrete in the crowding tub, working alley and restraining area if a full slab is out of budget.
West of the Brazos and into Bosque County it flips: thin soil over limestone, easy drainage, and a rock hole for every post. Our guides to setting posts in clay and setting posts in rocky ground cover both.
How big should a holding pen be
This is where extension numbers help most, because guesses tend to run small.
| Pen | Calves to 600 lb | Yearlings, 600 to 1,200 lb | Mature cows, cow-calf |
|---|---|---|---|
| Holding pen | 14 sq ft per head | 17 sq ft per head | 20 sq ft per head |
| Crowding pen or tub | 6 sq ft per head | 10 sq ft per head | 12 sq ft per head |
| Working alley width (straight sides) | 18 in | 22 in | 26 in |
Source: University of Arkansas Cooperative Extension, Beef Cattle Handling Facilities. The same page gives corral fence heights of 60 inches for gentle cattle and 72 inches for flighty ones, with posts 36 to 48 inches in the ground.
For pairs, Ohio State adds the cow and calf figures: 20 plus 14 is 34 square feet. Their worked example is a 30 by 40 foot pen, 1,200 square feet, holding about 35 pairs.
Say you run 60 pairs outside Crawford. Sixty times 34 is 2,040 square feet. You could build one 40 by 52 pen, but two pens of about 30 by 35 (1,050 square feet each) usually work better: split the herd, work half, and still have somewhere to hold the rest. More small pens beat fewer big ones almost every time.
Ohio State also recommends water and some shade in at least one holding pen, which doubles as the place for a sick or newly bought animal. In a Central Texas July, that shade matters if cattle will stand for long.
Sorting pens off the chute
One pen lets you gather cattle. It does not let you sort them. Sort pens sit at the exit of the squeeze chute so each animal can be turned into its group as it leaves: calves one way, cows another, culls into a third.
The straight-pen template in Kansas State’s bud box publication (linked in the bud box section below) shows three sort pens off the squeeze chute, with a 45-degree angled fence section that helps turn cattle back toward the pasture or pens. That is a sensible default. Size each sort pen with the holding pen figures above, for the largest group you will ever cut into it. If weaning day puts 30 calves in one pen, it needs about 420 square feet (30 times 14), not the 200 that looked fine on paper.
Hang the sort gates where the person at the chute can reach them.
The lane and the gates
The alley from the holding pens to the working area is a lane, not the single-file chute. Ohio State calls for 10 to 12 feet wide. Much wider and it behaves like another pen, letting cattle turn back past you. Narrower than 10 feet and a nervous animal may come through you instead of around you.
Two rules for the gates, both from the same bulletin:
- Hang them in the corners. Cattle travel to corners. A gate in the middle of a fence line is a gate they walk past.
- Make holding pen gates at least as long as the lane is wide. Swung across the lane, the gate becomes part of the fence and turns cattle where you want them without anyone standing there.
Add a man-pass at every corner you might need to leave in a hurry.
Crowding tub or bud box
This is the design choice people argue about. Our corrals and working pens page gives the short version of which suits which operation. Here are the dimensions behind it.
The crowding tub
A tub is a curved pen, often a half circle, with a sweep gate that pushes cattle around to the alley entrance. Ohio State advises working small groups in the crowding pen, 8 to 10 head rather than 20, and says a circular area with solid sides works best, though it is harder to build. With straight fences, build one side straight and angle the other about 30 degrees, with the wide end of the funnel 8 to 12 feet across. If you sheet only one gate in the whole facility, make it the sweep gate: a solid gate pushes cattle to look for the only other exit, which is the alley.
The bud box
The bud box was designed by stockmanship instructor Bud Williams. Kansas State’s Designing a Bud Box for Cattle Handling (MF3349) describes a rectangular pen closed at one end, gated at the other, with the alley leaving at a right angle at the gated end. Cattle walk in, the gate closes behind them, they turn to go back the way they came, and the handler’s position sends them past into the alley.
The key numbers from that publication:
- Minimum box 12 feet wide by 20 feet deep, which processes about 5 or 6 mature cows at a time.
- Allow 5 to 6 feet of alley per mature cow, and never bring more cattle into the box than the alley will hold.
- A loadout box for semis runs larger; 14 feet wide by 30 feet deep is the common size they give.
- It is not a holding pen, and it is usually left open-sided.
Arkansas gives 12 feet wide and at least 20 feet long when working on foot, and 16 feet wide, no more than 30 feet long, when working horseback.
Which one
A tub costs more and takes more room, but it forgives a handler standing in the wrong spot. A bud box is cheaper and smaller and works very well for someone who has learned where to stand, though Kansas State notes inexperienced handlers may need some training. If you mostly work cattle alone and will learn the positioning, the box gives you more facility per dollar. If neighbors and day help will run it, the tub is the safer bet.
Solid sides or open sides
Both have extension support, because it depends on the part of the facility.
- Working alley and loading chute: solid, per Ohio State. Cattle move forward more easily when they cannot see people or the squeeze chute until they are nearly there. A solid, gently curved alley keeps the working area out of sight until they are committed. Avoid a sharp bend that looks like a dead end.
- Crowding tub and sweep gate: solid, per Ohio State.
- Bud box: open, per Kansas State, since the design relies on cattle seeing the handler and moving past.
Penn State’s beef handling systems guide states the trade-off: open sides let a handler use the flight zone and point of balance, but distractions have to be cleared first. A shirt on a post or a truck parked beside an open alley will stop cattle cold. Sheeting on a pipe frame also adds wind load, and Ohio State notes a solid-sided facility will likely need a catwalk. Plan for both in the pipe.
Sun, shadows and which way to face the chute
Cattle balk at glare and at hard shadow lines across an alley, and they move more willingly from darker areas toward lighter ones. Ohio State says layouts should keep cattle from looking directly into the sun, and suggests running loading and squeeze chutes north and south for summer handling.
That fits Central Texas well. Summer cattle work tends to happen early or late to beat the heat, which is exactly when the sun is low. A chute pointing east walks cattle into the sunrise; one pointing west walks them into the sunset. Run the working alley roughly north and south and the low sun comes from the side. If the site has a slope, point the alley uphill: the same bulletin notes cattle move uphill more readily than down.
Building it to last
A corral takes abuse a pasture fence never sees. Stressed cattle push and hit the same places every working day, which is why welded pipe is the usual choice for permanent pens. Our pipe fence page covers construction, and what size pipe for a pipe fence covers the pipe itself. Set posts 36 to 48 inches deep, as Arkansas recommends, with the deep end of that range on corners and gate posts, and put rails on the inside face (Ohio State’s advice too) so nothing sticks into the pen to catch a hip.
On cost, as general Central Texas market ranges: a setup for 20 to 30 head (holding pen, sorting pen, short alley and headgate) runs about $6,000 to $12,000. A full facility for 100 or more head, with a crowding tub, several sorting pens, a loading chute and a mounted squeeze chute, runs $18,000 to $30,000 and up. Each piece is quoted separately, and if you already own a squeeze chute it gets set into the new alley rather than bought again. Our ranch fence cost page has the per-foot prices for the fence around the pens.
You can build in stages. A holding pen, a lane and a headgate make a working facility; the tub or bud box, more sort pens and a loading chute can follow, as long as the first phase left room for them.
Get the layout right before the pipe goes up
The cheapest time to fix a pen is before anything is welded. Walk a working day on the ground: where the cattle come from, where the trailer parks, where each sorted group goes, where the sun sits at seven in the morning. Stake it out, and move the stakes until the flow makes sense.

Frequently Asked Questions
How many square feet per cow in a holding pen?
University of Arkansas extension recommends 20 square feet per head for mature cows, 17 for yearlings from 600 to 1,200 pounds, and 14 for calves up to 600 pounds. For cow-calf pairs, add the two: about 34 square feet per pair, so a 30 by 40 foot pen holds roughly 35 pairs. Crowding pens run tighter, around 12 square feet per mature cow.
What size should a bud box be?
Kansas State gives a minimum of 12 feet wide by 20 feet deep, which handles about 5 or 6 mature cows at a time. Arkansas extension suggests 12 by at least 20 feet on foot, and 16 feet wide by no more than 30 feet long when working horseback. Only bring in as many cattle as the single-file alley will hold.
Is a bud box better than a crowding tub?
Neither wins everywhere. A bud box is cheaper, smaller and simpler to build, and it works very well for a handler who knows where to stand. A crowding tub costs more and takes more space, but it is more forgiving when several people with different experience work the cattle. If you mostly work alone, the bud box is usually more facility per dollar.
Which direction should a cattle chute face?
Ohio State’s beef quality assurance bulletin recommends running loading and squeeze chutes north and south for summer handling, so cattle are not looking into the sun. In Central Texas, where summer work happens early or late in the day, an east or west facing chute puts low sun straight in their eyes. On a slope, run the alley uphill.
