Reference Field max length

[abhijats]

I want to understand the concept of max length for the Reference type of field, OOB it is 32.
but we can type more than 32 characters in that field while in other text field whatever the limit is set, can't type more than that.
So what is the logic behind this?
Please share.

A reference field always stores a sys_id that is 32 characters in length. The actual field that this is stored in is hidden when you look at a form but gets populated with the sys_id of the referenced record when you populate a valid value in the field you see. The field you actually type into is just for the display value of the reference field and the max length of 32 doesn't apply there.
