How Much Does a Bale of Hay Weigh?

A bale of hay has no fixed weight. Our three-string squares run 85 to 100 pounds, our two-string average 40 to 50, and our round bales are typically about 500. Weight varies because hay is baled in a field by people running a machine, not made in a factory: moisture, windrow thickness and baler pressure all move it. Ask the weight before you compare two prices, then ask about quality, because cost per pound only tells you half of what you need.

If you have ever tried to compare two hay prices and ended up more confused than when you started, you are not alone. One seller quotes a price per bale, another quotes a different price per bale, and the bales are not the same object. So the question that actually lets you compare them is this: how much does a bale of hay weigh?

The honest answer is that it depends, and the reasons it depends are worth understanding, because they are the same reasons your bales are not all identical either. A "bale" is a shape, not a unit of measure.

What Our Bales Actually Weigh

Most pages will give you a range they copied from another page. Here are ours.

• Three-string small squares: 85 to 100 pounds. We set the baler for 85 to 88. Bales come in heavier when the hay does: our teff three-string has been running about 96 pounds lately, and some three-string alfalfa got heavy on us and is closer to 94.
• Two-string small squares: 40 to 50 pounds on average.
• Round bales: typically about 500 pounds.
• Our big alfalfa bales: about 1,200 pounds full, or roughly 600-pound halves if you want one you can actually move.

Every one of those is a bale average, and that phrase is doing real work. It is not a hedge. The rest of this guide explains what it means, because once you understand it you will read every hay quote differently.

Why Two Bales Off the Same Field Weigh Different Amounts

Hay is not made in a factory. It is made in a field, at night, by a person running a machine, and the field is not the same from one end to the other.

Moisture is the first variable. We aim for 13 to 15 percent moisture going into a bale. Too dry and the leaf shatters and you lose the best part of the plant. Too wet and it can heat, mold and spoil. On a good flat field with no low spots, bale weights can be very consistent. Any low spot picks up a little more moisture, and the bales coming off it weigh more.

Density is the second. We run electronic scales on the back of the baler, and they give us a ten-bale average. That is a good gauge, not a precise number for any single bale. We can raise or lower the pressure to move the weights up or down.

Then there is the part almost nobody explains. Bale weight comes down to how many strokes of the plunger go into each bale. Drive into a thin windrow and you get more strokes per bale, packing it tighter, and the bale comes out heavier at the same pressure setting. Come out of a thin spot into a heavy one and the strokes per bale drop, sometimes from 24 flakes down to 13, and the bale comes out lighter.

And here is why you cannot simply fix it as you go. There are always three bales sitting in the chamber of the baler. So when the weights move, you do not see it until three bales later. You look at the readout, realize you need to change the pressure, and by then a few bales have already gone by. There is a lag in both directions, every time. That is exactly why we call it a bale average and not a bale weight.

We have a ground guy who runs around checking bale weights through the night while we are baling. It helps. It does not make every bale identical, and anyone who tells you their bales are all the same weight is telling you something about their sales pitch rather than about hay.

The Scale

We keep a 5,000 pound certified scale at the yard in Williston.

Every big bale we sell is weighed on it, and we check our bale average against it as well. Customers occasionally ask us to put three-string bales on it, and most of the time they come out at what we say.

Once they did not. A customer asked us to weigh her bales and they came out light. We made it right and made an adjustment. What had happened is the ordinary thing: the baler operator had not got his pressure up in time coming into the windrow, made a run of light bales before it was caught, and they went on a truck to Florida. We would rather tell you that than pretend it cannot happen.

How Much Does a Round Bale of Hay Weigh?

Our round bales are typically about 500 pounds a piece. Treat that as a typical figure rather than a promise, because a round bale is the hardest bale to pin down: you cannot set one on a scale out in the field, so the number comes from hauling a load and working back to an average from the total.

If you are comparing round bale prices, ask the same question you would ask about any bale: what does it weigh, and how do you know? For the square and big bales we carry right now, see our current hay.

Where People Actually Get Caught: Big Bales

If you are going to get burned on bale weight, this is where.

A 3x3 bale runs anywhere from 650 to 900 pounds. A 3x4 runs anywhere from 1,000 to 1,500. Those are enormous ranges, and here is the problem: you cannot pick up a 900 pound bale to check. You cannot pick up a 600 pound bale. So you are taking the number posted on the board on trust, and unless there is a certified scale on site there is no way to verify it. Our own alfalfa big bales come in at about 1,200 pounds full, inside that 3x4 range, or roughly 600-pound halves.

That is the single biggest gap between what a buyer thinks they bought and what went on the trailer. It is not usually anyone being dishonest. It is that nobody weighed it.

How Much Does a 3x3x8 Bale of Hay Weigh?

A 3x3x8 is a 3x3 big square, 3 feet by 3 feet across and 8 feet long, and it runs anywhere from 650 to 900 pounds. That 250 pound spread is exactly why you ask whether anyone actually weighed it before you compare prices.

How to Compare Two Quotes

Work out the cost per pound. Take the price, divide by the bale weight, and you have a number you can put next to another seller's number. A cheap bale that weighs 40 pounds can easily cost more per pound than a pricier bale that weighs 90.

But cost per pound only gets you half the way, and this is the part we would push back on if you called us with two quotes in your hand. Most of the time the real difference is not bale weight at all. It is quality.

Ask what the relative feed value is. Ask when it was cut. Are you buying overgrown, stemmy hay that sat too long, or hay cut at the right time? Two bales at the same cost per pound can be very different feed, and the horse knows even if the spreadsheet does not.

So: weight is what makes two quotes comparable. Quality is what tells you which one to buy.

Does Western Hay Weigh More Than Florida Hay?

Not really, and this is a common misunderstanding. The weight per bale is not that different. The difference is quality.

The South gets a lot of rain and the hay grows fast in sandy soil that does not carry the nutrients a heavier loam soil does, and that shows up in the feed value. Western hay grows at high altitude, above about 3,500 feet, in a cool climate, and it grows slower. You generally get more color and a higher relative feed value out of it.

When people buy western hay on purpose, what they are usually buying is consistency. Across the board you can be fairly confident of what you are getting. That is the real reason, not the weight of the bale.

Why We Do Not Sell By The Ton

We get asked this regularly, so here is the straight answer: it is an accounting nightmare, and that is genuinely the whole reason.

We are not hiding behind bales. We have a certified scale and we will tell you what our bales average. Selling by the ton would change how every order, every invoice and every delivery is counted, for a difference most customers would not feel.

The Questions We Get Every Week

"How do you get your hay so green?" Cutting timing, curing, and a climate that cooperates. Color is not the whole story on quality, but it is not nothing either.

"Why does my horse clean up every bale of yours?" That is the consistency thing again, and it is the reason most of our repeat customers give for coming back.

"Why is there bleaching on the outside of the bale?" Sun on the outer layer. It does not mean the hay inside is bad.

"Is every one of your bales going to weigh exactly what is on the board?" Probably not. We are trying to make the best product we can and Mother Nature is still in control. Sometimes a bale comes out at 100 when we advertised 88. We are not going to take it back off you and swap it for a lighter one. That is what a bale average means, and it cuts both ways.

One last thing, and we mean it. Nobody asking about bale weight is asking a stupid question. Most people genuinely do not know, and they deserve an answer rather than a brush-off. Bale weights matter. If they did not, we could sell you a pile of leaves and call it 50 pounds.

Frequently Asked Questions

How much does a bale of hay weigh on average?

It depends on the bale type, and there is no universal average. Ours run 85 to 100 pounds for a three-string square, 40 to 50 for a two-string, and about 500 for a round bale. Across the industry you will see wider ranges quoted. Moisture, how thick the windrow was, and how much pressure the baler was running all move the number, which is why we talk about a bale average rather than a bale weight.

Why do bales of the same type weigh different amounts?

Because hay is baled in a field, not made in a factory. A low spot in the field picks up more moisture. A thin windrow puts more plunger strokes into the bale and packs it tighter. And there are always three bales in the chamber of the baler, so when the operator corrects the pressure, the correction does not show up for another three bales. Off the same load, bales can vary by up to about 10 pounds.

Why is a round bale harder to weigh than a square?

You cannot set a round bale on a scale out in the field. You have to haul a load and work back to an average from the total.

What should I ask when comparing two hay quotes?

Ask the bale weight so you can work out cost per pound, then ask about quality: relative feed value, and when it was cut. Weight makes two quotes comparable. Quality tells you which one is actually the better buy.

Do you weigh bales for customers?

We have a 5,000 pound certified scale at the yard. All our big bales go across it and we check our bale average against it. Customers occasionally ask us to weigh three-string bales too.
