The Hausdorff dimension measures the local size of a space taking into account the distance between points, the metric. Consider the number N(r) of balls of radius at most r required to cover X completely. When r is very small, N(r) grows polynomially with 1/r. For a sufficiently well-behaved  X, the Hausdorff dimension is the unique number d such that N(r) grows as 1/r<sup>d</sup> as r approaches zero. More precisely, this defines the box-counting dimension, which equals the Hausdorff dimension when the value d is a critical boundary between growth rates that are insufficient to cover the space, and growth rates that are overabundant.

豪斯多夫维数测量一个空间的局部大小时,会考虑到点之间距离的度量。考虑半径最大为 r 的球数 ''N'' (r) ,需要完全覆盖 ''X''。当 r 很小时,n (r)以1/''r'' 增长多项式。对于一个表现足够好的 ''X'',豪斯多夫维数是唯一的数 d,这样当 r 趋近于零时, N(r)增长为1/r<sup>d</sup> 。更确切地说,这定义了盒子计数维度,当值 d 是不足以覆盖空间的增长率和过度充裕的增长率之间的关键边界时,它等于豪斯多夫维数。
