what is the difference between apple watch series 4 40mm and 44mm?
The smaller of the two Series 5 watch sizes has a height of 40mm; the larger, 44mm. ... The 40mm Apple Watch has a display size of 394x324 pixels The 44mm Apple Watch has a display size of 448x368 pixels Again, this year's small watch has a slightly bigger display than last year's big watch. Let that sink in.
