Actually 26 dimensions follows more simply from the math. In non-super string theory, it is the only number of dimensions that is not mathematically singular.

However, all the strings are closed in 26 dimensions and so only force can exist, no matter. In physics terms only boson particles or strings can exist in 26-d --- no fermions, or open strings.

Fermions can exist in 10 dimensions, again from the math. They also can exist in 9 and 11 dimensions, 11 is the dimensionality of M theory, where two 10-d worlds are connected by the 11th dimension. Some think the other world is dark matter and dark energy.
