Floating isles can spawn anywhere in the sky, and as larger maps have higher sky, Floating Isles gain more diversity in their heights. I had an instance when one Island spawned right above another - i can post a map fragment if you want. However it seems that minimal height above an actual ground level is a preset, and is about 50-70 blocks. On smaller worlds Floating Isles have less oportunity to spawn higher, so they are almost always 50-90 blocks from the ground.
