DO NOT I REPEAT DO NOT USE THE PIXEL-ZONE ISOMETRIC TUTORIALS.

Whoever wrote them does not understand 2:1 isometric fully. he loses a lot of compression in places, and gains some in others. the square on which he defines the circle is not actually square, invalidating his form.

a real vertical square will end up about 88% as high as its undistorted width, or in perspective close to 125% of the distance covered (so if your tile block is 32px wide, then the height of the cube should be 20 pixels, *not* 16).

Here are some common cube sizes drawn in this method:

The astutue will notice that this is not 100% accurate - the value is actually a bit less than 125% (true ratio involves an arctangent), and the higher sizes should estimate accordingly - 1 pixel less starting at 32. However, I keep the 5:4 method, as this ensures that all smaller cubes can tile on themselves to line up precisely with the larger ones, and that patterning can be achieved with relative ease.

A mistake is a mistake.

The same mistake twice is a bad habit.

The same mistake three or more times is a motif.
