Squiers are modeled pretty closely after Fender Strats as far as dimensions go. Thinner body, but otherwise pretty close. I'm pretty sure nut width is exactly the same, but you might find some variations in neck shape & thickness (same as you would with different Fender Strat models/years.) The difference comes in more with quality of materials, quality of craftsmanship, and (sadly) the quality of life in the country of manufacture.

There is a 3/4 sized Squier model. Maybe that's what you had the first time?
