Artboard Size

Hi, newbie here

Based on the Adobe Help Center Page, I learned that the artboard should be at least 3,000x 5,0000 pixels (15mp). I have couple of my stuffs with the artboards 4,000 x 4,000 and 4,000 x 3,000, so they're not below 3,000 but not hitting 5,000. Did my artboards meet the requirements or should I increase them?

Thanks
