Systems and methods for improved delta angle signaling for blocks in video compression are provided. A method includes encoding a bitstream that includes a picture. The encoding includes obtaining a nominal angle of a current block of the picture for intra prediction; obtaining a nominal angle of at least one neighboring block of the current block for intra prediction; determining whether to signal all allowed delta angles of the nominal angle of the current block, or only a subset of the allowed delta angles of the nominal angle of the current block, based on a comparison between the nominal angle of the current block and the nominal angle of the at least one neighboring block; and signaling, within the bitstream, all the allowed delta angles or the subset of the allowed delta angles of the nominal angle of the current block based on the determining.
