How Tall Should I Make Raised Garden Beds?

When it comes to creating a raised garden bed, one of the most important considerations is determining the optimal height. The height of your raised garden bed will impact factors such as plant growth, soil depth, drainage, and ease of use. In this article, we will explore the recommended heights for raised garden beds based on various factors, including the type of plants you want to grow and the purpose of the bed.

Recommended Heights for Growing Vegetables

If you are planning to grow vegetables in your raised garden bed, the recommended height can vary depending on the specific plant. However, a general guideline is to have a minimum height of 12 inches. This height allows for proper soil depth, improves drainage, promotes better aeration, and reduces strain on your back.

For leafy greens and herbs, a raised bed height of 6 to 12 inches is sufficient. Root crops like carrots and radishes require a deeper bed of at least 12 inches to accommodate their growth. Fruiting plants such as tomatoes and cucumbers may need a raised bed that is 12 to 18 inches deep to provide ample space for their root systems.

If you want to have a raised garden bed that can accommodate a variety of vegetables, a height of 16 to 18 inches is recommended. This allows you to grow a range of plants while ensuring they have enough room to thrive.

Purpose of the Raised Garden Bed

The height of your raised garden bed can also vary based on its purpose. If you are primarily using the bed for growing fruits and vegetables, a height range of 8 to 36 inches is recommended. However, a common choice among gardeners is around 18 inches.

On the other hand, if you are using raised garden beds as visual dividers or seating surfaces, a taller height is preferred. For these purposes, the height can range from 24 to 42 inches, depending on your specific needs.

Finding the Right Balance

While there are recommended heights for raised garden beds, it’s important to consider other factors as well. Accessibility, aesthetic appeal, expense, and critter control are all aspects that should be taken into account when determining the height of your raised beds.

If you have physical limitations or prefer to garden at a comfortable height, you may want to opt for a taller raised bed that requires less bending or kneeling. Additionally, the height of your raised beds can contribute to the overall aesthetic of your garden, so choosing a height that complements your landscape design is important.

Expense is another factor to consider. The taller the raised bed, the more materials you will need to build it. So, if budget is a concern, you may want to choose a height that meets your needs without breaking the bank.

Lastly, critter control is an important consideration. If you are dealing with pests such as rabbits or groundhogs, taller raised beds can provide a barrier and help protect your plants.


When determining the height of your raised garden beds, it’s important to consider the specific plants you want to grow, as well as the purpose of the beds. For vegetable gardening, a minimum height of 12 inches is recommended, with taller beds being suitable for larger plants such as tomatoes and cucumbers. If you are looking for a versatile option, a height of 16 to 18 inches can accommodate a variety of vegetables.

Remember to also consider factors such as accessibility, aesthetic appeal, expense, and critter control when deciding on the height of your raised garden beds. By finding the right balance, you can create a functional and beautiful garden that meets your needs.
