I am just guessing these of the top of my head so I may be wrong. but it is at lease

 

2 Master Details and 20 lookups.

 

But there is also limits when Querying in SOQL how many times you can select chilren rows and transverse parents. I belive you can go up 10 levels high

I think total 40 Custom Relationship both lookup and master-detail. If any one is sure about the no. of relations then please confirm and share the offical salesforce link or document.

We can have 40 Look up fields for any standard object and custom object.

And we can have 2 Master - detail relationships for only custom object.

Custom Relationship Fields - 40 per Object (2 Master Detail Relationships and 38 Lookup Relationships OR 0 Master Detail Relationships and 40 Lookup Relationships)

Custom Relationship Fields - 40 per Object (2 Master Detail Relationships and 38 Lookup Relationships OR 0 Master Detail Relationships and 40 Lookup Relationships)

I confirm the above 100% because Goto Object >> View Objects >> Object Limits >> Custom Relationship Fields  = 40

how many lookup exists on an object ? how we count it via apex ?
 
thisisrajjainthisisrajjain
Total Relationships (including Lookup and Master Detail) on a single object, we can create 40 relationship fields.
Number of Relationships you can have is :
Number of Lookup = Total Relationships - Number of Master Detail Relationships
           38               =          40                   -                        2

Hi,

Greetings!

You can create up to 25 lookup fields in the standard and custom objects both.
But you have an advantage in standard objects in that you already have some standard lookup fields.
So you can create an extra 25 lookup fields with standard objects.
And you can create up to 2 MD fields in custom objects.

If you find your Solution then mark this as the best answer. 

Thank you!
