How much maximum space in floppy?

The maximum storage capacity of a standard 3.5-inch floppy disk is 1.44 MB. There were also earlier floppy disks, such as the 5.25-inch version, which typically held 360 KB or 1.2 MB depending on the format. Additionally, some high-capacity variants existed, but they were not widely used. Overall, floppy disks are now considered obsolete due to their limited storage compared to modern storage solutions.
