A meter roller for an agricultural metering system includes a flute and a recess positioned adjacent to one another along a circumferential axis of the meter roller. The flute and the recess are configured to meter flowable particulate material from a storage tank to a material distribution system via rotation of the meter roller. In addition, a first circumferential extent of the flute is at least 1.5 times greater than a second circumferential extent of the recess along an entire longitudinal extent of the flute and the recess, and the entire longitudinal extent of the flute and the recess is greater than the first circumferential extent of the flute and the second circumferential extent of the recess.
