Just like a bed, people tend to outgrow their homes, making shed building an essential project for any homeowner. 

A shed has many uses, and storage is only one of them, so knowing the purpose will also guide a homeowner on the right size of the shed they need for their homes. A too-small shed will only address the need for building another, so when it comes to shed size, the bigger, the better for a home.

Standard Shed Sizes 

There are many shed sizes to choose from, going from the smaller to the largest extent possible that it could feel like a barn. One consideration is the purpose which can dictate how small or large a shed should be according to a homeowner’s specific needs.

There are many smaller types of sheds measuring 6 by 8 feet, which is the equivalent to 48 square feet. There are mid-size sheds at 9 by 12 feet or 120 square feet and bigger ones at 12 by 12 feet or about 144 square feet.

Larger sheds are also available at 14 by 20 feet or 280 square feet to even bigger ones at 14 by 28 feet or 392 square feet to 14 by 32 feet or 448 square feet.

This is more or less 48 square feet to something larger at 8 by 10 feet or about 2.4 to 3 meters which covers the area of 80 square feet. 

This small shed will keep anything hidden in them dry and free from all the pests and environment that will increase decay and rusting of many equipment. A small shed is the most appropriate for a smaller home to ensure that the separate shed is not taking up all the space outside the house. 

Medium Shed Sizes 

Medium shed sizesOne of the most common shed sizes is the medium shed because they are the midway between being cost-efficient, taking up the lawn space, and also the ability for more storage capacity compared to smaller sheds.

These sizes range from 90 to 120 square feet, large enough for many homeowners who need the space and don’t need so much room for bigger equipment. 

The medium shed with a size of 8 by 12 feet will cover around 96 square feet. This is the size most used by standard lawns. A bigger size is 10 by 10 feet or 3 by 3 meters, covering an area of 100 square feet.
