Make an archival box at home

Why make your own boxes?

Sometimes, you won't be able to find the exact size of the box you need for an object or set of objects.

The acid-free boxes available commercially will be either too big or too small for your shelves or for your objects and getting bespoke sizes can be a bit pricier.

In these cases, it's best to just make an archival box yourself. It's not difficult! Below, I give you some basic instructions to make your own boxes.


  • Archival board / acid-free board
  • Box cutter
  • Ruler (ideally metallic) and right angle ruler
  • Protected surface
  • Pencil and eraser
  • Linen tape
  • Brass pins
  • Awl or something to make small holes

Step-by-step instructions


Know the measurements you need. Make sure you know the size of your object in all 3 dimensions: Length, width and height. Make sure you add a few inches in every direction so that the box is not a tight fit and allows you to put in other packing material to cushion your object (polyethylene foam or acid-free tissue paper). Make sure your corners are 90° or your box will not come out straight.


Draw the basics of your lid. You basically need 2 squares (or rectangles), one inside the other, with the lines going all the way to the edges to denote where the flaps will bend.

Cut only one side of each of the corners that will make up the flaps. Make sure you don't accidentally leave a side without its corresponding flap. Lid with cut edges

Repeat the steps to make the base of your box. Remember that the size of the outer square will determine the height of your box. Make sure you make the inside square 5mm smaller on each side to ensure a tight fit with your lid. Base drawing

Abuse all the folding lines a bit by passing over them with a blunt point. Then, fold up the flaps and use an awl to make small holes that will hold the lid and base together. Make sure the holes align. Insert brass pins. Lid with pins

Purposefully place your pins on different side corners in the lid and box to avoid double thickness of brass pins when attempting to close the box.

Reinforce the lid and base edges with linen tape. Reinforced lid
