Sign prediction technology for video coding are generally described. An example device includes a memory configured to store video data, and processing circuitry in communication with the memory. The processing circuitry is configured to determine that a block of the video data stored to the memory is eligible to be coded using sign prediction, to perform the sign prediction with respect to one or more transform coefficients of the block only if the block meets a predetermined criterion, wherein the predetermined criterion is based on at least one of: a width of the block, a height of the block, a coding mode used to code the block, or a position of one or more sign-predicted transform coefficients within the block, and to code the block based on the sign prediction performed with respect to the block.
