| Not sure if there is a way. However some reasonable estimations may be made
following the formula described in this technet article.

| Hi Adeel
Like how much a user weighs? Typically, an average 72 Kg adult user consumes only 3.7Kb in Active Directory. All objects take up one row in AD within the JetBlue ntds.dit database based on the X.500 object model with the exception of multi-linked values (groups etc), and the database has been tested for up to 40,000,000 objects. Performance impact is negligent for up to 1M objects.
Obesity may occur when customising the schema to add attributes with large blobs.
Here is an estimate which may help specifically for users:

| As Rick pointed out there is no known way to sharply measure the object "size". There are some methods to do estimations though. Thus the question (that you did not answer): What do you need this information for?

| As it has already been mentioned there is no way to get the extract size of
an individual object in the dit. However, there is a book called Building
Enterprise Active Directory Services, Notes from the field, (its no longer
in print but there are second hand copy around ISBN 07356-9860-1), which has
a detailed charter on determining the size of objects in the dit. The
figures are based on the Windows 2000 (these are same figures in the technet
article) so the sizes are not correct to Windows 2003 or Windows 2008 but If
you really want to know the size of an object in the dit, you can use the
test methodology to get the average size of an object.

| Its been a few years, but I seem to recall having a conversation on this
with both ~Eric and Brett in person while sitting around a table eating
snacks and again if I recall correctly, it was a bit complex and in the end
the answer wasnt going to be all that exact and not much better than just
adding 1000 objects and watching to see what happens.

Why would he need that data? Unless he gives an answer to this there is
not too much sense in digging into methodology ...

| This is all a bit analogous to the position of the .NET / CLR team on
user efforts to calculate the size in memory of an object... That
information is not available, it's none of our business and it's
highly subject to change in the future, so don't get too comfortable
in thinking you can know the answer precisely. 
I tend to agree that any solution that has hard dependencies on these
hidden implementation details is likely to be very brittle; just go
with the flow, use the experiential results as a guide.

| I'm sure those kind of estimation would be useful to many. Eg. Sizing,
cap planning (I did say estimation..)
Eg, if you have a 200 domain controllers with 16gig ram, dit size at
10gb and an acquisition activity in the air. Ie. Will we have to cater
for upgrade before or after the 10k users, 12k computers come in..

| The article provides the details for the users and few other object types, the book provides a lot more and impact of adding additional attribute types to objects. The Windows 2000 AD Sizer tool is still available for download on the Microsoft download site, but like the information in the article and book these are only based on Windows 2000 schema. You can use these figures for rough sizing, previously I have used these figures plus 15-20% for Windows 2003 and Exchange 2003 estimates and they have been pretty close.

Subject: Re: [ActiveDir] AD Object Size
I'm sure those kind of estimation would be useful to many. Eg. Sizing,
cap planning (I did say estimation..)
Eg, if you have a 200 domain controllers with 16gig ram, dit size at
10gb and an acquisition activity in the air. Ie. Will we have to cater
for upgrade before or after the 10k users, 12k computers come in..

OK, if it's this, a rough estimate is pretty much enough. There's docs
about this on the web, links have been quoted here.
If the OP needs different information he should tell us.

| Estimates are better than accuracy in many instances in any event unless you are timing the 100M Olympic sprint. It's impossible to buy 3.7Kbs of disk space for every user you have. What happens when a new user joins. Chaos... AD down, log files full.
It's like going to the petrol pump and putting in 2.7124 litres of fuel so that you can get to work.
There's nothing wrong with being highly professional in your work while simultaneously estimating instead of looking for accuracy. I might be over simplifying this without an understanding of what the real reasoning is behind this level of required accuracy.

| Here is an interesting way to retrieve all users accounts (and other
objects) from your AD (with all the attributes/properties) that contribute
to the accounts' sizes and exporting them into XML files for review.
http://dmitrysotnikov.wordpress.com/2009/06/08/find-large-objects-in-ad/
Perhaps that can serve as an estimation tool as well.

Ah, but you still can't know the cost of storing that object on the
directory server through this method... what if the entry has a long
string attribute, and that attribute is substring ("tuple") indexed?
Does JET Blue store DirectoryString, UnicodeString,
CaseInsensitiveString, etc., all as UTF-8, UTF-16, or something else,
potentially making a short string "longer" than a seemingly longer
binary attribute? How much space does it take to store and index
objectCategory, or backlinks, or any of the many other special AD
things?

| You're not replicating whole objects other than when you spin up a new DC so you're only looking at the changes and you can pretty easily measure those...
