Hi,
Yes the custom lookup fields on both the objects are 25 only.
But there is an advantage in the standard object where u can get some more lookup fields by standard functionality .
Apart from that u can have 25 custom lookup fields in standard object and custom object.
Thanks

Hi,
Maximum number of Lookup realtionships on a Standard Object is :25.
These 25 are custom lookups fields and the standard will not be counted in these.
Thanks

So, please confirm if the maximum number of lookup relationships on standard object is 25 and also on custom object is 25 only?

Ok, thanks Anil for your quick responses.
Anil - Can you please explain what 'standard functionality' will allow one to get more than 25 lookup relationship fields on a standard object? Thanks much!

Thanks.@Dushyant, the current limits, as of February 2017, are as follows:
MAX # of Master-Detail Relationship Fields, per Object (Standard or Custom) -- 2
MAX # of total Relationship Fields (Master-Detail + Lookup), per Object (Standard or Custom) -- 40
Hope this helps!

And agreed. It's time they update that help page, that's for sure!!
Check page 239 of this release notes. http://resources.docs.salesforce.com/190/latest/en-us/sfdc/pdf/salesforce_summer14_release_notes.pdf
Limit of 40 relationships in an object. BUT you can only have a MAX of 2 Master-Detail not matter what. So 40 lookups OR 38 lookups and 2 MDs OR 39 lookups and 1 MD.
Hard Limit is 50.

Roll-up summary fields are different but related to Master-Detail Relationships in Salesforce, which is the main topic being discussed in this thread around its limits. You cannot create Roll-up summary fields for two objects with a lookup relationship. You can only do so if two objects have a Master-Detail Relationship.
Moving on, the hard limit for creating Roll-up summary fields within the master object of a Master-Detail Relationship is 25. It used to be 10 but is now 25. No way getting around this limit. But I would recommend looking into a free managed package called Declarative Lookup Rollup Summary, which could potentially open up more possibilities for you for rolling up data between lookup relationships. Good luck!
