What Are The Standard Hay Bale Dimensions And Weight?

Hay bales are a great option for livestock feed and bedding, as well as decoration. Hay bales come in various sizes, depending on the type of hay and the intended use. Knowing the dimensions of hay bales is important when storing, transporting, or using them.

A common size for a rectangular hay bale is approximately 36 inches (91 cm) in width, 18 inches (46 cm) in height, and 14 inches (36 cm) in depth.

Standard Hay Bale Dimensions?

The size, density, and weight of hay bales can significantly influence their nutritional content, market value, cost of feeding livestock, and ease of transportation and storage. Farmers should carefully consider whether to use small or large hay bales, as choosing the right size for their needs can help them maximize their time and energy.

Small Hay Bales Dimensions

Baling hay in large amounts may seem like an efficient use of resources, however, this is not necessarily the case. For those caring for a limited number of livestock, small square hay bales are an ideal option. These bales are easy to transport by hand and come in a variety of sizes, depending on the number of strings used to hold them together.

Two-String Hay Bales

Two-string bales are the most commonly used hay bales, measuring 14” in height, 18” in width, and 35” in length. On average, these bales weigh between 50 and 60 pounds. If a horse is fed two-string small square hay bales twice daily, they should be able to get through one bale in a week. Round bales are an efficient way to store hay, particularly for small farms. One round bale is the equivalent of 10-12 square bales, making them a great choice for reducing waste and increasing storage capacity.

Three-String Hay Bales

Three-string bales measure about 16 inches in height, 22 inches in width, and 44 inches in length. Generally, they weigh around 100 pounds, held firmly together by three pieces of baling twine.

Properly adjusting the settings of your square baler will enable you to achieve desired dimensions for your bales. With precise tuning, you can ensure that your bales are uniform and the desired size.

Large Hay Bales

Small, square hay bales may be appealing for their convenience, but for larger farms, the time and effort required to create such bales can become quite burdensome. This makes it impractical to use the smaller bales for larger-scale forms. Large, round bales of hay are a great option for farms with large numbers of animals. This is because they provide a convenient way to feed multiple animals at the same time. This efficient bulk delivery method saves time and energy, making it a popular choice amongst livestock owners.

At a size of 5ft x 6ft and weighing around 1500 lbs., hay bales of these dimensions offer farmers an efficient and cost-effective way of creating bales. For example, on average, each cow consumes 32.5 pounds of hay every day. Therefore, five large hay bales measuring 5 feet by 6 feet can feed roughly 30 cows in a single week.

Dimensions vs. Density

While size is an important factor to consider when selecting the right hay bale, other factors should also be taken into account.

The density of a hay bale is an important factor when considering size and weight. A denser bale will contain more foliage while weighing more than a larger bale due to the tight wrapping of the hay.

A typical loosely wrapped hay bale can measure 8 feet in length, 4 feet in width, and 3 feet in height. It can weigh up to 1,300 pounds or 590 kilograms.

A bale of hay with more grass packed per square inch would have the same measurements as a traditional bale, but its overall weight could reach up to 1,500 pounds or 680 kilograms. This is due to the increased density of the hay.

What Is The Best Size Of Hay Bale For Me?

The size of the hay bale you need will depend on several factors, including the number of animals you have and their dietary needs, as well as the length of time you need to feed them. A general rule of thumb is to provide 2-3% of an animal’s body weight in hay per day.


When selecting the right hay bale, size, and density are two important factors to consider. Small square bales are an ideal option for those caring for a few animals, while round bales are better suited for larger farms. Large hay bales offer the most efficient and cost-effective way of creating bales. Ultimately, the size of the hay bale you need should be based on the number of animals and their dietary requirements, as well as how long you need to feed them.

How do you calculate hay bale weight?

You can calculate hay bale weight using a weighing scale. Put the ball on the scale and measure how much it weighs. You can guess the weight without a scale by multiplying the bale’s length, width, and height by a conversion factor if you don’t have access to one. There’s a conversion factor that depends on how dense the hay is, but it’s around 0.02.

Weight (in pounds) ≈ (Length x Width x Height) / Conversion factor

How heavy is a standard square bale of hay?
