The same-sized cage needed for one medium parakeet, 30”H x 24”W x 24”D, is the minimum cage size for two medium parakeets. Parakeets need more vertical space than width and enough space for their wingspan when taking flight, so when possible, increasing the cage size to account for two birds’ wingspans would be even better. Increasing the vertical space to 36” is a common recommendation, in addition to a couple of extra inches for width and depth when possible.
