Hardware Cloth vs Chicken Wire: Which to Use

Hardware cloth vs chicken wire is not a close call once you know what each is for. Hardware cloth is a galvanized grid with small square openings, sold here in 1/2 in and 1/4 in; chicken wire is a net of 1 in hexagons twisted from thin wire. Utah State Extension says it plainly: chicken wire “is not a barrier to predators” and should only keep chickens in. This page compares the two on opening, gauge and price per square foot from dated store listings, then shows where each one belongs on a coop and run and how to fix it. The full predator plan, apron and latches included, lives in our predator proof coop guide.

Hardware cloth vs chicken wire at a glance

The rolls below are the ones our cost engine prices: all Acorn Hardware, read at the Lowe’s Atlanta-Edgewood store on Oct 8, 2026.

Opening size decides what gets through

The opening is the first number to read. UNH Extension asks for openings smaller than 1 in so a predator cannot reach through, and the Cooperative Extension notes that raccoons sometimes pull a bird’s head through the wires of an enclosure. A 1 in hexagon sits right on that line. Smaller animals go through the mesh itself: UC Davis found mice in coops even with 1/2 in holes, and the Cooperative Extension says least weasels can squeeze through holes as small as 1/4 in, which is why it expects them to get through chicken wire.

Gauge: why the chicken wire number misleads

Wire gauge runs backward: the lower the number, the thicker the wire. The chicken wire we priced is 20 gauge, which on paper is heavier than the 23 gauge of the 1/4 in cloth. So gauge alone does not settle it. Utah State still says most predators can tear through chicken wire and rats can bite through its thin wire, and UC Davis says even smaller predators rip through it, while no source we read says either of hardware cloth. Read the gauge to compare two hardware cloths, not to compare cloth with netting.

What the extension services say about each

The sources split on 1/2 in against 1/4 in. None of them puts chicken wire on a coop.

Cost per square foot, from real rolls

Price per square foot swings as much between rolls of the same mesh as between meshes, so compare by the square foot, not by the roll.

Every roll we priced, per square foot

All prices from Lowe’s Atlanta-Edgewood, Oct 8, 2026, rounded to the cent per square foot.

Two oddities stand out. The 3 ft x 100 ft roll of 1/2 in cloth cost $1.30 more than the 3 ft x 50 ft roll, for twice the mesh. And the 2 ft x 100 ft roll was cheaper in 1/4 in than in 1/2 in. Shelf prices move like that, so check the roll next to the one on your list. One more catch: the 2 ft x 50 ft roll of 1/2 in cloth carries a page title that says 23 gauge, not 19, so read the label before you pay.

What it adds up to on a real build

The same 4x8 coop for six hens with its covered 8x8 run, priced three ways by our engine at those shelf prices. The meshed area is about 342 sq ft: the eave vents, the gable vent, a 4x8 sheet under the floor frame, the run walls, the door, the chute around the ramp and the apron.

Swapping 1/2 in cloth for chicken wire saves $209.12 on a $2,754.24 list. The 731 washer-head screws stay the same whichever mesh you pick, $100.52 in boxes of 120 at the same Lowe’s store, so the fixing costs as much on the cheap mesh as on the strong one.

Welded wire, the third option for the run

Oregon State fences its run with 1 x 2 in mesh. Our designer offers that as the cheaper run wall: 1/2 in hardware cloth up to 36 in, where small animals and reaching paws work, and 1 x 2 in galvanized welded wire, 16 gauge, above it. The one store-brand roll we found was YARDGARD 3 ft x 25 ft at the Tractor Supply store in Augusta, Kansas, $62.99 on sale (was $69.99) on Oct 8, 2026, which is about 84 cents a sq ft. It is not cheaper per square foot than a long roll of hardware cloth, so the saving only shows when the short roll fits your wall.

Where each mesh belongs on a coop and run

This is where the comparison turns into a cut list. Every place below is a place our plans put mesh, and the mesh named is the one the designer checks for.

On the coop: vents, windows and the floor

Every vent and window gets hardware cloth, because Maryland asks for 1/2 in cloth over windows and UC Davis wants nothing weaker on the coop itself. The floor gets it too: Utah State recommends heavy-gauge mesh beneath the subfloor and warns that rodents get in through holes the size of a nickel or a quarter. On the 4x8 plan that is a 48 x 96 in sheet screwed across the underside of the floor frame, plus the two eave vent strips and the gable vent, about 37 sq ft in all. Vents and their placement are covered in our coop ventilation guide.

On the run: walls, door, roof and apron

The run walls are hardware cloth from the ground to the top rail by default, put on the outside of the posts as NC State asks. The door is framed and meshed in the same cloth, and so is the apron strip at the base. The roof is the one place the default is not mesh at all: corrugated panels, because mesh carries no snow, with a hardware cloth roof as an amber option up to 30 psf of snow. How the run is framed, posted and roofed is in how to build a chicken run and the covered chicken run guide.

Where chicken wire still earns a place

Utah State gives chicken wire one honest job: keeping chickens in. That leaves a short list of uses where nothing is trying to get past it: a daytime fence that keeps hens out of a vegetable bed, a temporary divider inside a run that is already closed in hardware cloth, or a pen for a few hours while you are outside with the flock. None of those carries the flock through a night.

Choosing between 1/2 in and 1/4 in hardware cloth

Once chicken wire is off the list, the real choice is the opening. Our default is 1/2 in, and the designer offers 1/4 in with one setting.

When 1/2 in is enough

Utah State’s range is 1/4 to 1/2 in, Maryland names 1/2 in for windows and UC Davis sets 1/2 in as the maximum, so 1/2 in sits inside what most of the sources accept. It also stops anything that reaches through, since UNH only asks for openings under 1 in. For a raised coop with a solid floor and mesh underneath, in a yard where raccoons, foxes and hawks are the worry, 1/2 in does the job. It is not always the cheaper of the two: on the rolls we priced, 1/2 in cost less per square foot in three of the seven sizes sold in both openings.

When to step down to 1/4 in

Go to 1/4 in where mice or weasels are the problem. UC Davis saw mice get through 1/2 in, Colorado State asks for no opening over 1/4 in on a closed coop, and Maryland wants few gaps over 1/4 in near the roosts. On our 4x8 example the 1/4 in version cost $30.12 less, because the 2 ft roll happened to be cheaper that day. That will not hold at every store or for every size, so price both.

Gauge is our choice, not a source’s

No extension source we read names a wire gauge; Utah State only says heavy gauge under the floor. Our list names 19 gauge for 1/2 in and 23 gauge for 1/4 in because those are the gauges the store sells in each opening. A heavier 1/2 in cloth, with a lower gauge number, only helps.

How to cut and fasten hardware cloth

Good mesh fixed badly is a weak wall, and the fixing is the same job whichever cloth you buy. The predator guide covers the run bands and the apron; here is the part that applies to every piece.

Pick the roll width before you cut

The rolls come 2, 3 and 4 ft wide, and the engine plans each wall as bands of those widths stacked up the posts, so that every band edge lands on a rail. Choosing widths first means fewer seams and less waste. On the run of the 4x8 example, a 48 in band from the ground and a 36 in band above it cover the wall with one joint, set on a 2x4 rail laid on edge. Cut along a row of openings with tin snips and keep gloves on: every cut leaves a line of wire ends.

Lap it, screw it, every 6 in

Our default laps the cloth 1 in onto the framing on every side and fixes it with 1 in washer-head screws every 6 in of edge. The washer head clamps the wires flat against the wood instead of passing through an opening. On the 4x8 example that is about 731 screws for 342 sq ft of mesh, roughly two screws per square foot. The plans call for screws rather than staples, and we have no test to quote for staples, so we stay with what clamps.

Outside the posts, with no floating seams

NC State says to fix the run wire to the outside of the posts, because wire on the inside can be pushed in by a persistent predator. The same thinking applies to every seam: where two pieces meet, both edges land on framing and both get screwed. A seam that hangs between posts is one a raccoon can work open, which is why the band joints in our plans always sit on a rail.

Price your own coop with each mesh

The numbers above are for one design. Yours will differ with the size of the coop, the run and the rolls your store stocks.

Switch the mesh in the designer

Open the 4x8 coop with 1/4 in hardware cloth in the designer, then switch the mesh setting to compare. Every change recounts the rolls, the screws and the price, and chicken wire turns the mesh checks red so you can see the saving and the reason not to take it side by side.

Start from a plan with the mesh drawn

The 4x8 chicken coop plan has every mesh piece cut and listed, roll by roll, with the run and its apron. When the checks are green, the builder’s plan for your exact design is $29, with the cut list, the mesh cuts and the full hardware list.
