Macintosh SE Cardboard Box Specifications

All dimensions in inches, unless otherwise specified.

Principal box measurements: 19.5 x 20 (height) x 15.5

The cardboard box structure is that of a Regular Slotted Container (RSC).

  • All flaps are of the same height, approximately half the length of the shortest side on the top/bottom faces.

  • There are rounded corners between the side faces.

  • There is a "manufacturer's joint" to join the end-most side faces together.

Box Layout Dimensions

First of all, let's compute the corner radius using photo propotions and our box measurements, on the "19.5 inch wide" face photo.

5.20 / 501.40 = 0.01 proportion
Length 19.5 in, so effective corner radius = 0.202 inches

This is similar to the half-inch circumference measurements of another similar sized box that I have. That is, "circumference" as the length along one rounded corner.

So, what is the circumference of our rounded corner?

0.202 * 2 * 3.14 / 4 = 0.318

So, the radius is what you subtract from the box dimensions to get the dimensions of one box face directly. The circumference is the joint length between faces you add into your model. You don't subtract this from the vertical length since those edges are scored without significant rounded corners.

  • Corner join lengths: 0.202
  • Side face dimensions: 19.096 x 20, 15.096 x 20
  • Corner circumference: 0.318

Now, if the desired corner radius was 1/4 inch, the numbers would work out more nicely. So, let's simply present some nicer potential numbers for posterity.

  • Corner join lengths: 0.2

  • Side face dimensions: 19.1 x 20, 15.1 x 20

  • Corner circumference: 0.314

  • Corner join lengths: 0.25

  • Side face dimensions: 19 x 20, 15 x 20

  • Corner circumference: 0.393

Another point to note. With these dimensions, this means that the flaps are a little longer than half the length of the shortest face in the cardboard design. This is as intended because the total box dimensions are still the same.

  • Flap length: 15.5 / 2 = 7.75

Well, almost... I might recommend adjusting to 7.706 inch tall flaps, as per the photo measurements. After testing from printing and folding a miniature paper model, I can attest that the longer flaps are a little too long, so please do shorten the top and bottom flaps accordingly. After a careful look at the flaps, maybe even a little shorter would still be better.

Box fusing tab, let's call that 2 inches, I'll have to obtain the actual measurement later.

Box Design Layout Max Extents

So, let's determine the maximum physical extents to lay out the two-dimensional design canvas, erring on the side of over-specifying the required space to allow for minor adjustments later.

  • Height: 20 + 7.75 + 7.75 = 35.5 inches

  • Width: 2 + 0.25 + 19.5 + 0.25 + 15.5 + 0.25 + 19.5 + 0.25 + 15.5 = 73 inches

Now, for the sake of a box design layout, give ourselves one inch extra space on all 4 sides.

TOTAL PDF LAYOUT DIMENSIONS:

WIDTH: 73 + 1 + 1 = 75 inches HEIGHT: 35.5 + 1 + 1 = 37.5 inches

Cardboard Material Specifications

What type of cardboard is used to manufacture this box? The box certificate printed on the box provides ample data on this. Though the data is clearly visible in the retraced vector drawing, the data is also copied here for posterity.

Fonts

Apple Garamond font:

Download directly as follows:

curl -L -o apple_garamond.zip 'https://dl.dafont.com/dl/?f=apple_garamond'

For miscellaneous sans-serif fonts, I did not quite do as good of a job in font matching as I could have. These are the fonts that I used.

  • Real font for sans-serif default font alias: DejaVu Sans
  • Liberation Sans
  • Liberation Sans Narrow

PLEASE NOTE: The last line on the "Keyboard not included * Mouse included" line is written in Japanese. Of course it does not use the same Apple Garamond font, it's much less decorative. But, point in hand, these are the characters to use, almost an exact match return from using Google Translate, compared to what was originally printed on the box. Right now the strokes are just directly hand-drawn, I'll have to hunt around for a better matching font later.
