What is the size range of a rubriblast?

A rubriblast is an early erythroid precursor that is relatively large, with a prominent nucleus and basophilic cytoplasm. As erythroid cells mature, they decrease in size, so the rubriblast remains bigger than later precursors and much larger than mature red cells, which are about 6-8 μm in diameter. This makes the typical size around 14-20 μm. The other size ranges are smaller and align with later stages or mature erythrocytes, not the large basophilic rubriblast.
