The width of the neck MIA and MIM's, Squiers etc. are different. The MIA seems wider, or at least the strings seem further apart.

Does the width of the neck on the classic Stratocasters from the 1950's and early 1960's reflect the width of current MIA or MIM?

I remember when we were free!

Vintage Fenders mostly have 1-5/8" neck widths.

Back in the day there were a few custom choices of neck widths from Fender besides the normal 1-5/8".
Vintage Fender neck width codes
A = 1 1/2" wide at the nut.
B = 1 5/8" wide at the nut (normal size).
C = 1 3/4" wide at the nut.
D = 1 7/8" wide at the nut.

There are a few widths available today depending on model (if you want to pick your own neck width, then go to the Custom Shop). Click on the "specs" tab when looking at guitars in the products section here. You'll see the current nut width specs listed. For example vintage reissues are 1.650”. American Standard is 1.685". So yes, the modern styled Fenders are slightly wider at the nut compared to vintage and reissue Strats.

MIM Standards = 1.650”
Highway 1's = 1.685"
American Deluxe = 1.6875"
MIM Classic Payer = 1.650"
...you get the idea, just click on the "specs" tab.

I hope that info was useful.
