Here is the online crystallite size calculator
Using Scherrer equation one can calculate crystallite size from XRD data.
Crystallite size = 0.94 * x ray wavelength / beta * cos (theta)

Note: Don't bother about β in radians. All the entries are in degrees. The conversions are taken care in the computing code.
Caution: The crystallite size may appear large from the above method compared to the size determined from other methods. However, these numbers will be within the tolerance limits. More suitable for entry level research students.
