Design and comfort don't have to be compromised when living in a small space. Having a bed is essential, but knowing how to build a loft bed can maximize your bedroom's space. With a loft bed, you can create a cozy sleeping area while still having ample storage for other furniture and knick-knacks [^1^].

Step 1: Gathering the Materials

To ensure a smooth and cost-efficient project, it's important to have the right materials. Choose materials that will fit your preferred mattress size. If you're up for the challenge, you can even cut your own boards and posts. Here's what you'll need for a simple loft bunk bed [^2^]:

  • 1 - 4 x 8 x ¾ inch plywood
  • 4 - 4 x 4 inch at 8-ft length posts
  • 4 - 2 x 6 inch boards, 8 ft long
  • 6 - 2 x 2 inch, 8 ft long
  • Wrench
  • Drill
  • Level
  • Measuring Tape
  • Screwdriver
  • Nuts, lag bolts, and screws
  • Clamping device (optional)

Step 2: Measure the Ceiling Height

Before proceeding, it's crucial to measure the height of your ceiling. Ensure that there's enough space for the loft bed and consider the size of the mattress you intend to use. You may also want to add stairs, shelves, a desk, or storage beneath the loft bed frame [^3^].

Step 3: Construct the Loft Bed Frame

Once you've determined the loft area and ceiling height, it's time to build the loft bed frame. Begin by cutting or constructing a box using four of the 2 x 6-inch boards. Create pilot holes in the boards, and connect them using nuts and lag bolts. Use drywall screws to secure the plywood on top of the frame as the base and support for the mattress [^4^].

Step 4: Attach Legs to the Bed Frame

To ensure stability, drill pilot holes in the bed frame and attach an 8-foot 4 x 4 inch post on each side using nuts. Double-check that the legs are level before drilling. Optional clamping devices can help keep the legs in place while drilling. This step ensures the sturdiness of your loft bed [^5^].

Step 5: Attach The Rails

Connect the 2 x 2 inch boards across the legs using screws or lag bolts. These boards will serve as rails or stairs leading to the mattress. Ensure that they are securely attached to provide safety and stability [^6^].

How to Build a Full-Size Loft Bed

The step-by-step instructions above can also be applied to building a full-size loft bed with a few adjustments. A full-size bed offers more width compared to a twin-size bed. To accommodate a full-size mattress (54” x 75″), add an additional 15 inches to the width. Remember to work on a level surface and utilize clean and accurate boards for a sturdy construction. Pre-drill and countersink screws to hide their heads, and consider using wood glue for added concealment [^7^].

Additional Ideas to Consider


When shopping for materials, consider the style and vibe you want to achieve. Wood and metal frames are popular choices, each offering their own unique advantages. Wood offers a wide range of colors, shapes, and sizes, while metal frames provide lightweight construction and versatility.


Both wood and metal frames are reliable and durable. Wood ensures a sturdy build and comes in various options, while metal frames offer longevity, easy maintenance, and portability.


Your loft bed should not only be stylish and durable but also comfortable. Regardless of the material you choose, prioritize compact and well-designed loft bed plans to ensure stability and prevent any risks of toppling [^8^].
