Here is the 2015 edition, featuring all the units at their official sizes as they appeared in the StarCraft Field Manual, which I provided the size charts for. This is the full size link, preview below:
I will continue the charts with all of the extra units independently as well.
FALL 2014 UPDATE:
The 3 year anniversary has been reached! Since some of the old image links are dying now, here's a celebratory recap post, on page 100.
This thread will never die! But things are kind of on standby until new material from Legacy of the Void comes out. The most recent uploaded versions of the charts from over the summer are here:
There are more hero units and ships to go.
I'm also slowly phasing in 3D models instead of some of the drawings, but the overall project is still just to draw every unit.
November 24 (2013): The Heart of the Swarm Capital Ships chart is finished! Here's a low-quality preview:
From now on, I'll be intermittently adding random stray units until LotV comes out, when there'll be another big overhaul.
HERE ARE THE GROUND UNITS OF THE HOTS UPDATE
Here's a low-quality preview (outdated now), you can download the full size from my deviantart link above. (Though the full size is a 10MB image, watch out).
Below was my original text.
I'm creating a reference of Starcraft units from the side, to scale. The whole thing will be in the format of a large image with all the units lined up to scale, but I'll also create a Flash version where you can zoom in and out. So, I'll be drawing each and every unit in profile for use in this reference.
Does anyone have any interest in this project or in which units I should do next?
EDIT: I'll keep updating the most recent version of the lineup into the first post as I go. The final Flash version should have the following features:
-Ability to compare any two units side-by-side
-Ability to scroll to zoom in and out along the different sized units, from Larva to Leviathan
-Ability to check whether to look at all units or only those of a certain race
Here was the poster-format image for WoL. I first made this thread on October 9, 2011, and finished the WoL poster on November 9, 2012.
(Keep in mind that that version is very outdated!)
