Bob, why wouldn't you just look at Sleepy Ck website?......it says the reg jaw is 5 13/16 and offset jaw is 6"

Having gigged you a bit..hopefully consructively...you've also told me you have a small catalog collection.
The Minnesota Trapline catalog shows both inside and outside spreads....as do several other FREE catalogs, like from Sterling Fur and Schmitt Enterprises and NWtrappers and Southeastern Outdoor and FnT and PCS.

In my opinion, we all need several catalogs at hand.

I find it much faster and easier to compare prices and info when I can open catalog A, then find same product in catalog B, then open catalog C, etc, etc.
This is my experience and hope it helps.

I see you are new here and could be a new trapper also...….WELCOME to the t-man family!

Besides, the Sleepy Creek website doesn't give an inside jaw spread for the #3 offset, or for any of their long springs.

Our regs for trap size in NC are very clear. They even have diagrams showing how the measurements apply so there is no confusion about length or width. One diagram for foot holds and one for body grips.

This is my states regualtion on trap size:
No. 2 Traps

It is unlawful to set on land any trap with a jaw opening any larger than 5.75 inches.

Now can someone clarify inside vs outside spread? Inside being two closest measurements across the jaw? And outside being two farthest, which I’m guessing is dependent on the thickness of the jaws?

And any clue as to what my State is referring to? I would guess inside.
