## Guide to Alternative ISO Containers Standart

### Why AISO?

- The fact of the existence of "New ISO" and Nacon's ISO with a width of 11 blocks suggests that using the ISO 9x9 format is not suitable for many players.
- The 9x9 format is not suitable for use on road vehicles, since most cars are built with a width of 11 or 13 blocks, and the container of 9x9 blocks looks disproportionately small for them.
- The "New ISO" and Nacon's ISO have the same length as the 9x9 standard which causes distortion of the proportions of ISO containers (24 blocks length for 20ft container).
- This standard has aspect ratios as close to real as possible, taking into account a width of 11 ingame blocks width.
- The even number of container length blocks does not allow them to be suspended by the center of mass on the cable when using a crane. Also, containers with an even number of blocks do not look too good on rail wagons, which usually have an odd number of blocks in length. All containers of this standard have an odd number of blocks in length.
- The use of basic connectors like in 9x9 ISO causes energy consumption. The use of electrical connectors is not.

**Why length is not 29 blocks?**

Because if you make a container 11 blocks wide, then observing the correct proportions of a standard ISO 20ft container, you will get 27.33 ingame blocks of length, not 29. Calculations at the end of the guide.

Here you can find the container template in order to make your own.

### Dimensions

This standard is built on the principle of stacking 10-foot containers (13 blocks long) with a separation of 1 block between them.

In this way:

- 10 ft is a 13 blocks long.
- 20 ft is a 13+1+13=27 blocks.
- 30 ft is a 27+1+13=41 blocks.
- 40 ft is a 41+1+13=55 blocks.

Width is 11 blocks, and basic hight is 12 blocks (because in real containers have 8 ft wide and 8′ 6″ height). Like in real word you can make containers with more height, called "high-cube" (9′ 6″ ft) is a 13 blocks height ingame.

If a height of 12 blocks is not suitable for your creation.

You can use 11 blocks height, provided that the connectors from the bottom and top are installed outward, which will allow mutual compatibility in height between containers of 11 and 12 blocks in height.

10 ft

- 11 width x 12 height x 13 long.

20 ft

- 11 width x 12 height x 27 long.

30 ft

- 11 width x 12 height x 41 long.

40 ft

- 11 width x 12 height x 55 long.

### Size Calculation (Not Interested)

The length of the containers is selected based on the need to respect their proportions as for real containers, taking into account that their width should be equal to 11 game blocks, which is ingame 2.75m.

Basic 20 ft real ISO container has:

- Length 19ft 10.5in (6.058 m).
- Width 8ft 0in (2.438 m).
- Height 8ft 6in (2.591 m).

**Calculation of container lengths**

Since we want to have a container width of 11 blocks in the game, we get:

- Real widht 2.438 m / 11 blocks = 0.2216 scaled meters for each block

So, length is:

- 20 ft is 6.058 m / 0.2216 = 27.33 blocks ingame, so we chose 27.
- Scale is 27x0.25=6.75/6.058=1.11.

- 30 ft is 9.1 m / 0.2216 = 41.06 blocks ingame, so we chose 41.
- Scale is 41x0.25=10.25/9.1=1.12.

- 40 ft is 12.192 m / 0.2216 = 55.01 blocks ingame, so we chose 55.
- Scale is 55x0.25=13.75/12.192=1.127.

As you can see, the selected length sizes have almost the same scale factor, so we believe that the size is chosen well - it reflects the real proportions of the containers. The selected container sizes are convenient to use, have an odd number of blocks, gaps between formfactors of 1 block (which is convenient when loading several containers into 1 vehicle), and this format scales from 10 to 40 feet or more.

Larger containers are created by symmetrically lengthening on both sides of a 40-foot container while maintaining its connectors. 63 blocks for 45ft, 73 blocks for 53ft.
