Hi Rose!

Welcome to GuitarTricks, and congrats on starting your musical journey!

My favorite acoustic guitar for learning is the Taylor GS-Mini. It is larger than a travel guitar, smaller than a full-size guitar.

I have one and LOVE it. 

I would have a look at those online, and if the price is doable, for you, go for it. If it's not doable, make note of the dimensions of the Taylor GS-Mini and see if you can find something less expensive that is decent quality, and a nice mellow size for learning. 

Have fun!! - Lisa
