Most sites, including AO3, do not report individual chapter length/size.
FFF does have a
log page feature that can record the total word count and added word count each update.
From defaults.ini:
Code:
## include a Update Log page before the story text. If 'true', the
## log will be updated each time the epub is and all the metadata
## fields that have changed since the last update (typically
## dateUpdated,numChapters,numWords at a minimum) will be shown.
## Great for tracking when chapters came out and when the description,
## etc changed.
include_logpage: false
## If set to 'smart', logpage will only be included if the story is
## status:In-Progress or already had a logpage. That way you don't
## end up with Completed stories that have just one logpage entry.
#include_logpage: smart
## items to include in the log page Empty metadata entries, or those
## that haven't changed since the last update, will *not* appear, even
## if in the list. You can include extra text or HTML that will be
## included as-is in each log entry. Eg: logpage_entries: ...,<br />,
## summary,<br />,...
logpage_entries: dateCreated,datePublished,dateUpdated,numChapters,numWords,status,series,title,author,description,category,genre,rating,warnings
By default, log page records total word count (
numWords) at each update. You can also add metadata entry
words_added to
logpage_entries or assign it to a custom column using
custom_columns_settings.
words_added is calculated from the current updated
numWords -
numWords from last log page entry.
numWords only works when log page is used.
