A method and an apparatus for video coding are provided. The apparatus includes processing circuitry. Prediction information of a first block from a coded video bitstream is decoded by the processing circuitry. The first block is a non-square block and the prediction information of the first block is indicative of a first intra prediction direction mode in a first set of intra prediction direction modes that is associated with the non-square block. The first set of intra prediction direction modes has a first number of different intra prediction direction modes from a second set of intra prediction direction modes that is associated with a square block. The first number is a positive integer that is based on an aspect ratio of the first block. At least one sample of the first block is subsequently reconstructed by the processing circuitry according to the first intra prediction direction mode.
