Creating your own shipping box is more than just a DIY project—it offers a range of practical and strategic benefits that make it a worthwhile endeavor for individuals and businesses alike.
Purchasing pre-made shipping boxes, especially in non-standard sizes, can be expensive. By making your own, you can utilize recycled materials (such as old cardboard from packaging, cereal boxes, or appliance boxes) to significantly reduce packaging costs, which is particularly valuable for small businesses or frequent shippers.
Many items being shipped have irregular shapes or dimensions—think handmade crafts, delicate electronics, or odd-sized gifts. A homemade box can be tailored exactly to the item’s size, ensuring a snug fit that minimizes movement during transit and reduces the need for excessive padding.
Reusing cardboard to make shipping boxes reduces waste and lowers your environmental footprint. It diverts materials from landfills and decreases the demand for new cardboard production, which involves resource-intensive processes like logging and manufacturing.
You aren’t limited by the sizes available in stores. If you need a box urgently, you can create one on the spot using materials you already have, avoiding trips to a supply store or waiting for deliveries of pre-made boxes.
● Cardboard sheets (thickness depends on the item’s weight—heavier items need sturdier cardboard)
● Ruler or measuring tape
● Pencil or marker
● Box cutter or scissors (adult supervision recommended for sharp tools)
● Packaging tape (strong, clear tape works best)
Optional: Corner protectors, bubble wrap, or foam padding for fragile items
First, determine the dimensions of the item you’re shipping. Measure its length, width, and height. Add 1–2 inches to each dimension to account for padding (this extra space ensures you can wrap the item in bubble wrap or tissue paper without the box being too tight).
The cardboard sheet should be large enough to form the base, sides, top, and flaps of the box. For a basic rectangular box, the length of the cardboard will be (2 × height) + length of the item (plus padding). The width will be (2 × height) + width of the item (plus padding).
Using a ruler and pencil, mark the dimensions on the cardboard. Draw a rectangle for the base of the box, then mark lines for the sides (height) on both ends of the base. These lines will create flaps that fold up to form the sides.
Carefully cut along the marked lines with a box cutter or scissors to get the main cardboard piece.
Along the lines marked for the height, fold the cardboard upwards to form the four sides of the box. Ensure the folds are crisp—you can run a ruler along the fold line to make it sharper.
Use packaging tape to secure the vertical corners of the box. Apply tape along the inside and outside of each corner to reinforce them, ensuring the sides stay upright.
From the top edges of the two longer sides, cut flaps that are equal to the width of the box (plus a small overlap, about ½ inch). These flaps will fold down to close the top.
Once the item is placed inside (with padding, if needed), fold the top flaps down. Overlap them slightly and seal with tape along the seam. For added security, tape along the edges of the flaps as well.
For heavier items, reinforce the base by adding an extra layer of cardboard or taping a strip of cardboard along the bottom edges. You can also reinforce the top flaps with additional tape to prevent them from opening during shipping.
