*edit:* ~~a few ways, you can do the following
```bash
ipfs pin ls > pin_list
while IFS= read -r line; do
    ipfs object stat "$(echo "$line" | awk ' {print $1}') " | grep CumulativeSize >> sizes_in_bytes
done < pin_list
SIZE=0
while IFS= read -r line; do
    SIZE=SIZE+line
done < sizes_in_bytes
```

but thats a pretty verbose way and won't scale when your datastore grows in size. IMO you're better off partitioning your disk and using a dedicated partition to store ipfs stuff then you can just run a simple `df -hl`~~ -> a few ways, you can do the following
