A mask frame, a mask body, a mask and a method for manufacturing the same are provided in the embodiments of the disclosure. The mask frame includes a loop shaped frame body comprising an outer boundary and an inner boundary, the inner boundary defining a space for receiving a mask body. The mask frame also includes a forced side and a non-forced side, the forced side being subjected to a pulling force of the mask body, the non-forced side being free from the force of the mask body. A width between the outer boundary of the forced side of the mask frame and the inner boundary corresponding to the outer boundary decreases gradually in a direction from a middle position on the forced side toward the non-forced side.
