The partition size shown by fdisk (in 1024 bytes Blocks) is rounded; if an exact partition size is required it can be calculated by End - Start + 1 (fdisk shows End and Start in sectors). For example:
...
root@CW8:~#
...
fdisk
...
-l
...
/dev/sdb
...

End - Start + 1 is 1250261614 - 1224268508 + 1 = 25993107.

Length includes the EPBR, any following unused sectors and the logical partition itself.
Offset is the EPBR plus any following unused sectors.
First Sector is the first (and only) sector of the EPBR
The partition size is not displayed. It can be calculated from Length less Offset. For example:
...
