A Simple 6 Steps Guide on How to Make a Custom Cardboard Box

Making a personalized box can be used for a few good reasons that you might have noticed, as well as it could be used for several other and related reasons. Maybe it's a holiday season, and you're packaging a present that needs a form or structure package, or you'd benefit from a safe cardboard layer, or you'd like to fit a shape/size object into a storage/mailbox. You could make boxes for the things to sell on eBay, Amazon, etc. Having an item's own package minimizes the bulk, the weight, the need for additional packing content and thus eliminates postage/shipping fees. Everything you need is a second-hand carton, a box cutter, and packing tape.

It is a bit of a headache to find the right package for delivering products. Then why not make your own shipping boxes. An appropriate-sized package covers the item you are delivering and decreases shipping costs (smaller boxes typically cost less to ship). Shipping boxes are available from a number of retailers and office supply shops, so you can avoid this cost by making your own shipping boxes from the items you have on hand.

6 Steps Guide on How to Make a Custom Cardboard Box

1. Breakdown of a Cardboard

Split the box down, continuing by opening the tabs at the top and bottom of the box. Only unfold the tabs, or cut the box cutter into the tape, and then unfold the tabs. Put the box flat on its side and cut one of the edges from top to bottom so that you can unfold the cardboard again and end up with a long, smooth piece of cardboard.

2. Mark the corners according to the product

Now there's a long piece of the carton on the board. Place the item (in this case-framed image) on the cardboard where half the item's size is equal to the distance between the item and the edge of the cardboard. (So, if you had to roll the cardboard up on the piece, it would just be halfway around the side.) From top to bottom, cut very gently with the box cutter to make a line cut into the cardboard when the edge of the item meets the cardboard.

Don't break off the cardboard to remove it on this side! Only make a label with the blade that slices off the top surface of the cardboard! (We'll see later that this helps the cardboard fold perfectly.) On the other side of the piece, make another parallel cut line. Then roll the item on its side so that one side is still on the previous cut line and make another parallel cut line while the item is 90 degrees in the air.

Lay down the object to complete its 180-degree roll, hold one side of the previous cut line, and make another parallel cut line on the edge that just touched down on the cardboard. Now leave half the object's width as the gap on the cardboard (as we did in the first cut line) and cut off the remaining excess cardboard entirely, from top to bottom, using the box cutter.

3. Make a cut according to the size

Now, transfer the object to the top or bottom of the cardboard so that you can break it down to size. Don't bring the object to the exact end! You'll need to leave half the width of the side of the item as additional cardboard that can be rolled to the sides of the item. And leave half the width of the item as extra cardboard on the other side, break off the remainder of the surplus cardboard entirely from side to side.

4. Flipping and Folding

Now, pull the thing off the cardboard and turn the cardboard to the other side of it. Fold along the cut lines to see how simply and precisely the four corners of the box are bent and shaped! Place the object inside the package and shut it down. I'm waiting for the tape after I patch the ends, so it would be better for you to tape the box right now, where the edges touch from top to bottom.

5. Fix the sides of the box

Look at one of the two heads, and you'll see the hand of the object and some extra cardboard hangover. This is what is going to be used to flip over to shape the side of the box. You need to cut the uncovered corners to make four different tabs. Cut the inside out with the box cutter, start with the object and cut it out. After you cut the four corners of the side like this, make four cut lines on the outside edge where the cardboard folds around the slice. Echo this step on the other side of the box.

Then you're going to be able to tape the package. You can tape all of this at once or in bits. It depends on how much tape you think your box needs, but a good, well-cut fitted box only needs a line of tape along the sides where the edges intersect.

6. That’s it

If you have a delicate object, the bubble wrap it then fit in a personalized cardboard package. You may also branch out to create boxes to match other items, such as designing your own triangular box to fit posters, or an oblong or different shaped box to fit something. Yet that's not half of it. You saved the money by using less tape, no peanuts or plastic wrapping, and a higher postage/shipping cost if you're going to send with the smallest/lightest possible box regardless of shipping. And to note on top of that, you're recycling boxes by giving them a second life!


Always be careful while performing all that cutting stuff. The cutter can easily put the cut on your body. Make sure you wear gloves while you are using a blade or cutter. It would help if you had a cleaner to clean the room after this project and have a bad to through extra useless material in the trash can. Keep all the things away from children.
