If you've got the capacity to test, create one that's quite a bit
larger and see how much space it actually uses up when full, then use
that size in future. There's a header, and then the blocks are written
sequentially with an index block inserted ahead of each group of
data blocks.
Or try out thin LVs available in recent LVM releases/kernels for
an alternative 'sparse' approach.
