Abstract: Provided are video encoding/decoding methods and apparatuses for determining an intra prediction mode of a current block, based on a width and height of the current block. When the current block has a square shape in which the width and height are equal, the intra prediction mode of the current block is determined from among first intra prediction mode candidates including a plurality of predetermined intra prediction directions, and when the current block has a non-square shape in which the width and height are not equal, the intra prediction mode of the current block is determined from among second intra prediction mode candidates configured based on the non-square shape.
