The '''interplanar spacing''' or '''interplanar distance''' is the perpendicular distance between two successive planes on a family ([[Miller indices|''hkl'']]). It is commonly indicated as ''d''<sub>''hkl''</sub> and corresponds to the reciprocal of the length of the corresponding vector in [[reciprocal space]]:

<center>''d''<sub>''hkl''</sub> = 1/||r*<sub>''hkl''</sub>|| = 1/(''hkl'')'''G'''*(''hkl'')<sup>T</sup></center>

where '''G'''* is the [[metric tensor]] in reciprocal space and <sup>T</sup> stands for transposed vector.
