How to Build a Basic Storage Box

If you are unable to find a storage box that is a specific size, you can make your own with a flat piece of cardboard. Before you start the project, you will need to make a few basic calculations in order to choose the correct size of cardboard. This storage box has a separate lid, which is made in the same manner as the box.

Things You'll Need

• Cardboard
• Ruler or measuring tape
• Straight edge
• Box cutter
• Packaging tape

Instructions

1. 

   Calculate the width, length and depth of the box you want to make. Find an appropriately-sized piece of cardboard. The cardboard's dimensions should equal the length of the box plus two times the depth, by the width of the box plus two times the depth. For example, if you want a box that is 10 inches long by 5 inches wide, and 5 inches deep, you will need a piece of cardboard that is 20 by 15 inches.

2. 

   Draw a square in each corner of the flat cardboard. Each square should be the same length as the box's depth. For example, if you want the box to be 5 inches deep, draw 5-inch squares.

3. 

   Cut the squares from the cardboard. Use a straight edge and a box cutter.

4. 

   Run the box cutter along the perimeter of the box's bottom to make it easier to fold--but do not cut all the way through. Simply break the top layer of paper to allow the flaps to fold cleaner. Use the straight edge to guide the folds.

5. 

   Fold the flaps up and tape the edges of the box together.

6. Repeat the previous steps to create a lid for the box. Adjust the measurements accordingly.
