How to Fold a Paper Box


A folded paper origami box, also called a masu box, is beautiful in its functional simplicity. All you need is a piece of square paper. The finished box makes a great hiding place for small treasures. With a pair of boxes, you can use one as the box and the other as a lid to wrap small gifts. Read on to learn how to make a folded paper box.

You can use origami paper or fold any piece of paper diagonally from the corner to the opposite edge and trim off the excess. It is important that the paper is square since you are creating a box.

Use your finger to crease the fold, then open the paper again. You should now have two creases that intersect at the center of the square.[1]

Bring each corner to the center, so that the points are all touching. Crease the folds with your finger. Rotate the paper so it sits squarely in front of you, but don't unfold it this time.[2]

Fold over the bottom of the still folded triangles. Crease the bottom edge. You should have what looks like a necktie with two points.

Creating the Walls of the Box

For the purposes of the guide, the diamond furthest away from you formed by the "necktie" folds will be the "head" and the diamond closest to you will be the "foot." Match the bottom tip of the foot diamond to the bottom of the head diamond. Then, match the top tip of the head diamond to the top of the foot diamond. Crease along the long sides to solidify the folds.

Pull up the flaps along the long side to create the side walls of the box.

As you lift the head wall flap, the creases from previous folds should form two triangle shaped flaps that you will want to fold inwards. Be sure these triangles are folded inwards before proceeding. The head wall will fold over these triangle corners and the top triangle of the head wall will fit neatly into the bottom of the box where you will want to crease it snugly against the sides to keep the box together. After creasing, you should see a triangle on the bottom of the box.
