A method of efficient signalizing of picture size and partitioning information in a video bitstream, is performed by at least one processor and includes obtaining, from a sequence parameter set (SPS) to which a coded picture refers, a flag indicating whether the picture size and partitioning information of the coded picture is included in the SPS, and determining whether the obtained flag indicates that the picture size and partitioning information is included in the SPS. The method further includes based on the flag being determined to indicate that the picture size and partitioning information is included in the SPS, obtaining, from the SPS, the picture size and partitioning information, and based on the flag being determined to indicate that the picture size and partitioning information is not included in the SPS, obtaining, from a video parameter set (VPS), the picture size and partitioning information that is included in the VPS.
