The term ``fractal dimension'' is sometimes used to refer to what is more commonly called the Capacity Dimension (which is, roughly speaking, the exponent in the expression , where is the minimum number of Open Sets of diameter needed to cover the set). However, it can more generally refer to any of the dimensions commonly used to characterize fractals (e.g., Capacity Dimension, Correlation Dimension, Information Dimension, Lyapunov Dimension, Minkowski-Bouligand Dimension).
