Hi Nina, welcome. Good you found the guitar as a pastime to enjoy and keep your mind busy with something different than your everyday work. You’ll learn how to stretch your fingers and fret those chords without harmful strain. I few people here have ended using a reduced size guitar, often a 3/4 guitar, but I think it’s best to try with the full size guitar and trying to develop the ability of the hand to stretch before looking for other options.

Welcome to JustinGuitar and the Community. Speaking of old dogs …
I’m arriving late to your hello party, If you need any help with a lesson specific question or with any general guitar learning question then do not hesitate to ask. There are many good folk here who will happily offer help and encouragement to those coming up behind them on Justin’s Beginner Courses. They embody and carry the pay-it-forward ethos we have nurtured for many years in our community. There are many old hands too who have years and (hopefully) a bit of wisdom they can bring as they give their support to those hitting the road blocks - which we all do.
Just ask if you need anything.
Cheers
