Understanding the Concept of a Ton

A ton, in formal terms, is a unit of measurement that represents a large quantity of weight. In the context of hay, a ton refers to 2,000 pounds (or 907.18 kilograms) of dried, harvested grass. This standard measurement is used to quantify the amount of hay produced, purchased, or stored.


Understanding the concept of a ton is crucial when dealing with hay because it provides a consistent and reliable way to compare and manage hay supplies. Knowing the exact weight of a ton of hay can help you determine the appropriate amount of feed for your animals, plan your hay storage and transportation needs, and negotiate fair prices with hay suppliers.


It's important to note that the term "ton" can sometimes be used interchangeably with "bale," but these are two distinct measurements. A bale of hay is a compressed and tightly wrapped bundle of hay, and the number of bales needed to make a ton can vary greatly depending on the size and weight of the individual bales.


Hay Bale Sizes and Weights

Hay bales come in a variety of sizes and shapes, each with its own unique weight and characteristics. There are many types of hay, and here is a helpful article on estimating hay needs. The most common types of hay bales are:


  • Small square hay bales:

    These are the traditional, small rectangular-shaped hay bales that are smaller and can typically be handled by hand. They might also be called 2-string or wire bales of hay because they are tied with 2 strings by the machine that makes them. They usually weigh between 40 and 80 pounds (18 to 36 kilograms) each (but this varies by the type of hay, such as alfalfa, grass, etc.). They are usually 4 ft wide by 5 ft in diameter.


    There are also 3-string bales, which are made by a different machine. They are generally about 44 inches long and 22 inches wide.


Size Dimensions of Rectangular Hay Bales

(L x H x W) Weight

2 string bale 36” x 19” x 16”40 - 75 lbs.

3 string bale 44“ x 22” x 15”100 - 140 lbs.

Half-ton 6 ft x 4 ft x 3 ft 1000 lbs.

1 Ton 8 ft x 4 ft x 4 ft 2000 lbs.


  • Large square hay bales:

    Also known as big bales, large rectangular bales are larger and heavier than small square bales. They typically weigh between 800 and 1,200 pounds (363 to 544 kilograms) each.

  • Round bales:

    As the name suggests, these bales are cylindrical in shape and can be quite large and heavy. They are also called tone bales. Round bales typically weigh between 800 and 2,000 pounds (363 to 907 kilograms) each, depending on their size and the type of hay.

Size Dimension (Width x Height) Weight

Small 4 ft x 4 ft 400 - 600 lbs.

Medium 5 ft x 4.5 ft 720 - 950 lbs.

Large 5 ft x 6 ft 1270 - 1700 lbs.


The weight of a hay bale can be influenced by many factors, which might include the type of hay, the size of the bale, the moisture content of the bale, and the density of the bale.


Calculating the Number of Hay Bales in a Ton

To determine the number of hay bales needed to make a ton, you'll need to consider the average weight of the bales you're working with. Here are some general guidelines:

  • Small square bales: Approximately 25 to 50 bales per ton

  • Large square bales: Approximately 1.5 to 2.5 bales per ton

  • Round bales: Approximately 1 to 2.5 bales per ton

However, it's important to note that these are just rough estimates, and the actual number of bales per ton can vary depending on the specific characteristics of the hay.

To get a more accurate count, you can weigh a sample of bales and then calculate the number of bales needed to make up a ton. For example, if your small square bales weigh an average of 50 pounds each, you would need 40 bales to make a ton (2,000 pounds / 50 pounds per bale = 40 bales).

Knowing the exact number of bales per ton can help you plan your hay storage and transportation needs, as well as ensure that you're getting the right amount of hay for your livestock. For accurate counts of hay storage and usage, consider using farm record keeping software like Farmbrite to help calculate your hay storage and usage.


5 Factors That Can Affect the Weight of Hay Bales

The weight of hay bales can be influenced by several factors, including:

  1. Moisture content: Hay with a higher moisture content will weigh more than hay that has been properly dried. Excessive moisture can also lead to mold and spoilage, reducing the quality and weight of the hay.

  2. Density: The way the hay is compressed and baled can affect the density of the bale, which in turn affects its weight. Tightly compacted bales will generally weigh more than loosely packed ones.

  3. Hay type: Different types of hay, such as alfalfa, timothy, or grass hay, can have varying weights due to their unique characteristics and nutrient content.

  4. Bale size: As mentioned earlier, the size of the bale can significantly impact its weight. Larger bales, such as round or large square bales, will typically weigh more than smaller square bales.

  5. Bale shape: The shape of the bale can also affect its weight. Rectangular bales may have a more uniform weight distribution, while round bales may have a slightly higher weight in the center.

Understanding these factors can help you better estimate the weight of your hay bales and plan your hay management and storage strategies accordingly.


Tips for Purchasing Hay

When you buy hay for your livestock, you want to protect your investment. Hay that is moldy can make your animals sick. Depending on the animals you're feeding, like horses or lactating animals, you may have specific types of hay you want to look for. Like, ones with more or less calories or protein.


There are several important considerations to keep in mind:

  • Inspect the hay: Before making a purchase, carefully inspect the hay bales to ensure it is of good quality. Check for signs of mold, smell, excessive moisture, dust, obvious weed content, or other factors/damage that could affect the weight and usability of the hay.

  • Hay composition: Inspect the composition of the hay before purchase. High-quality hay usually has a high proportion of leaves, is a little crumbly but not dusty, and has few coarse stems or seed heads.

  • Weigh the bales: If possible, weigh a sample of the bales to get an accurate idea of their weight. This will help you calculate the total tonnage and ensure you're getting the right amount of hay for your needs.

  • Consider storage space: Hay bales can take up a significant amount of space, so it's important to plan for proper storage. Make sure you have enough room to stack and protect the bales from the elements, such as rain, snow, and direct sunlight.

  • Do they rotate their hay supply? To maintain the quality and freshness of hay, it's a good idea to rotate. Are they using the oldest bales first?

  • Get a hay analysis: You can send a sample away to understand the composition of your hay and if this hay has produced enough nutrients for your animals.


By following these tips, you can ensure that you're purchasing the best hay for your livestock.



Tips for Storing Hay


Whether you purchase hay or grow hay for your livestock, you want to protect your investment. There are some important factors to storing hay. Here are several considerations to keep in mind as you store hay:

  • Keep it Dry: Moisture is the enemy. Hay should be stored in a dry, well-ventilated area to prevent mold and rot. If hay gets wet, it can become a breeding ground for bacteria and mold, which can be harmful to animals. Try elevating the hay if possible. Store hay off the ground on pallets, racks, or shelves to prevent moisture from seeping up from the floor.

  • Use a Well-Ventilated Space: Air circulation is key. Make sure the storage area has good airflow. Poor ventilation can trap moisture and cause mold. Avoid plastic covers. While tarps or plastic might seem like a good option to keep hay dry, they can trap moisture inside and cause condensation. Use breathable covers if you need to protect hay from rain.

  • Stack Hay Properly: Stack hay in a way that allows air to circulate around the bales. This helps with drying and prevents moisture from accumulating. and avoid overly tight stacking. Ensure there’s enough space between bales for airflow, but don’t leave too much open space where the hay could fall over or become unstable.

  • Store in a Cool Area: Heat and shade are two considerations for where you might store your hay. Heat can cause hay to degrade faster. Try to store hay in a cool area away from direct sunlight or heat sources. Sunlight can bleach and deteriorate hay quality, so keep it shaded if storing it outdoors.

  • Keep It Away from Pests: Pests can contaminate hay. Mice, rats, and insects can damage hay or contaminate it with droppings. Consider using storage bins with lids, or ensure your storage area is tightly sealed.

  • Consider storage space: Hay bales can take up a significant amount of space, so it's important to plan for proper storage. Make sure you have enough room to stack and protect the bales from the elements, such as rain, snow, and direct sunlight.

  • Rotate your hay supply: To maintain the quality and freshness of your hay, it's a good idea to rotate your supply. Use the oldest bales first and replenish your stock with new hay as needed.

  • Monitor for moisture and mold: Regularly check your stored hay for any signs of moisture or mold, which can compromise its weight and quality. If you notice any issues, take immediate action to address them.


By following these tips, you can ensure that you're purchasing and storing hay in a way that maximizes its weight, quality, and usefulness for your livestock.

  5. "Weighing hay bales is unnecessary": Accurate weight measurements are essential for proper hay management, ensuring the well-being of your livestock, as well as maintaining compliance with local regulations.


By understanding these common misconceptions, you can make more informed agricultural decisions and better manage your hay supplies.


Alternative Measurements for Hay

While tons and bales are the most common units of measurement for hay, there are a few other ways to quantify and describe the amount of hay you have:

  • Pounds of hay: Hay can be measured in pounds, which is particularly useful for smaller quantities or when dealing with individual bales. This measurement is often used in retail settings or when purchasing hay for personal use.

  • Acres: Hay production is sometimes measured by the number of acres used to grow the crop. This can be helpful for estimating the total yield or planning for future hay needs.

  • A flake of hay: A flake of hay is a single slice or section of a hay bale. This measurement is sometimes used to describe the amount of hay in a specific portion of a bale. This is usually used when feeding livestock. You might consider this 1/8 of the bale.

  • Slices of hay: Similar to flakes, a slice refers to a thin section of a hay bale. This measurement can be useful for accurately portioning out hay for individual animals.

  • Stacks of hay: Hay can also be measured in the form of stacks, which are piles of loose, uncompressed, or unprocessed hay. This measurement is often used when estimating the total amount of hay available on a farm or ranch.

As you can see, there are many units of measuring hay. Understanding these alternative measurements can be helpful in different situations, such as when you are dealing with small quantities of hay or when communicating with others in the agricultural industry.
