What Are the Floating Shelf Sizes?

Floating shelves have become a popular interior design trend in recent years, offering a seamless and modern way to display and organize items. 

Whether you’re looking to showcase your favorite books and decorative pieces or create additional storage space in a room, selecting the right floating shelf sizes and depth is essential for both aesthetic appeal and functionality. Here, we explore the considerations that go into choosing the perfect floating shelf size and depth for your space.

For versatile needs, standard floating shelves come in widths of 12, 24, 36, 48, and 60 inches, and depths of 4, 6, 8, and 10 inches. Choose 24-inch wide shelves for versatility in most rooms or 48-inch shelves for a bold statement in larger spaces. Depth-wise, 6 inches serves multiple purposes, while 10 inches is ideal for bulkier items.

Choosing Floating Shelf Size

Choosing Floating Shelf Size

When it comes to floating shelf sizes, one size does not fit all. The dimensions you choose should complement the room’s layout, the items you intend to display, and the overall design aesthetic you’re aiming for. Here are some key factors to consider when selecting the appropriate floating shelf sizes.

Room Dimensions

The room dimensions are an important consideration when choosing the size of your floating shelves, because they need to work within the proportions of the room. By taking into account the size of the room where you plan to install the floating shelves, you can ensure that the size of the shelves doesn’t look out of balance in the space.


Your intended purpose for the shelves will impact their ideal size. If you intend to store books, electronics, or other items, you’ll need shelves that are wide and deep enough to hold them securely, while floating shelves for displaying picture frames can be much more shallow.

Wall Space

Measure the available wall space where you intend to install the shelves, and then work back from here to select an appropriate shelf size. Be sure to account for any obstructions like doors, windows, or electrical outlets..

Design Aesthetic

Floating shelves can contribute to the overall style of the room. Consider the design theme and choose shelf sizes that align with the chosen aesthetic. A rustic-themed room will lend itself better to chunky floating shelves, while a minimalist room will work best with floating shelves that are thin and sleek.

Weight Capacity

Different sizes of floating shelves will have different weight capacities, which means they will be suitable for displaying or storing different types of items. Larger shelves will not necessarily have a greater weight capacity, so be sure to check the maximum weight allowance for floating shelves before you stack heavy items on them.


If you’re planning to install multiple shelves as a set, think about their arrangement. Different sizes and depths can create visual interest and dynamic compositions. You’ll want to ensure that the shelves are arranged in a way that looks visually appealing but also offer practicality.

Standard Floating Shelf Width

Standard floating shelf sizes are designed to accommodate a variety of needs, from showcasing decorative items to providing storage for everyday essentials. Standard sizes offer convenience and are readily available from various retailers, but if you need a specific size of floating shelf, for example to fit perfectly in a particular place in your home, then you can have a custom floating shelf made.

Custom shelves will typically cost more to buy compared with standard size floating shelves, and they will typically have a longer lead time. Standard floating shelf width dimensions include:

12 inches

These compact shelves are ideal for small spaces, such as bathrooms or narrow hallways. They can hold a few small decorative items or act as a handy spot for keys and essentials. You could also use a 12-inch floating shelf to display a single plant or a small handful of books.

24 inches

This is one of the most popular sizes of floating shelves because it is so versatile. The 24-inch width works well in kitchens, bedrooms, and living rooms, and it can also be suitable for larger bathrooms or laundry rooms. This length provides ample space for displaying books, plants, or decorative pieces, or you can fit a basket on a 24-inch floating shelf for storing cleaning supplies or bath and body products.

36 inches

This is a medium-sized floating shelf that strikes a good balance between functionality and aesthetics. A 36-inch wide floating shelf could display a range of picture frames in various sizes or a group of houseplants.

48 inches

A 48 inch wide floating shelf will create a bold statement and offer substantial storage space. These are often used in spacious rooms, adding a focal point and enhancing the visual appeal of the space.

60 inches

It will work best in larger rooms such as living rooms or master bedrooms, and can operate as a space for creating a gallery wall, or displaying a collection of ornaments. Large floating shelves can also be functional in the kitchen, storing recipe books, pots of dried herbs, or glassware.

Standard Floating Shelf Depth

Standard floating shelf depths are pre-defined measurements that cater to a variety of purposes. The depth of a floating shelf determines how much space you have for placing items, and it also influences the overall aesthetic of the shelf. Common standard floating shelf depths include:

4 inches

These shallow shelves are ideal for creating a minimalist appearance. They work well for displaying small decorative items or picture frames and are often chosen for spaces where the primary goal is to enhance the decor..

6 inches

8 inches

Offering increased storage and display space, 8-inch deep shelves are a popular choice for functional and decorative purposes. They can hold larger items and are commonly used in kitchens, bathrooms, and entryways.
