When you’re buying a bunk bed for your child, the size and configuration you choose is important. Both your space availability and your individual family needs are important considerations. Before getting started, be sure to take measurements to ensure the bed you select will fit your floor space, then discover which size and configuration is right for your family in this Bunk Bed Size and Configuration Buying Guide.

Bunk Bed Size Considerations

There are a variety of bunk bed sizes available to meet your unique family needs and accommodate even the tightest spaces. The main three sizes to consider are:

1. Twin Over Twin

2. Twin Over Full

3. Full Over Full

In addition to looking at your available floor space, make sure to leave enough space between the top bunk and the ceiling. If you have low ceilings, consider a low bunk bed which is usually about five feet high.

The most popular type of bunk bed is the twin over twin. The average dimensions of a twin over twin bunk bed is 68”H x 42”W x 80”L. This type of bed takes up the least amount of room and are usually the cheapest option.

Whether your children share a room, or you just need more sleeping space for guests, the twin over twin bunk bed is an easy way to maximize floor space. This size of bed is a great starter bunk bed for young children. If you’re looking for a long-term solution, choosing a bunk bed that separates into two individual beds will ensure your child can sleep comfortably for years to come.

The twin over full bunk bed is another popular type of bunk bed. The average dimensions of a twin over full bunk bed is 68”H x 80”L with a top bunk width of 42” and a bottom bunk width of 60”. While this size of bunk bed takes up more room than the twin over twin, it provides more flexibility and more sleeping space.

This bunk bed size is a smart solution to comfortably accommodate an older child sharing a room with a younger child, or if you have three children sharing a room.

Full Over Full Bunk Bed: Sleeps up to 4

The full over full bunk bed is less common than the other two sizes, but it maximizes sleeping space. The average dimensions of a full over full bunk bed is 68” H x 60” W. Although this size of bunk bed is usually the most expensive option, it provides the most versatility.

The additional sleeping space this size of bunk bed provides makes it an ideal way to accommodate more children or give older children and teenagers more space.

Bunk Bed Configuration Considerations

Different bunk bed configurations are an easy way to personalize your child’s room. From the basic bunk bed to the L-shaped configuration, you’ll find the perfect bunk bed for your child’s room.

Basic Bunk Bed Configuration

The basic bunk bed configuration is one bed directly on top of the other. These bunk beds can usually separate into two individual beds and take up the least amount of floor space. If you’re tight on space, the basic bunk bed configuration is the way to go.

But don’t let the word “basic” fool you. With a variety of color options and ladder styles to choose from, your child can create their own custom bed.

L Shaped High Loft Bed Configuration

The L shaped bunk bed configuration has been gaining popularity. This configuration is a fresh take on the traditional bunk bed and provides more storage space. The L shaped bunk bed can accommodate the same number of children, but it does take up more floor space than the basic bunk bed configuration.

By joining a high loft bed with a matching twin bed placed in a perpendicular position, your child will have more room for storage and can even create their own study space.

Trundle Bunk Bed
