Hi guys , my question is this , buying strings for an acoustic guitar

are their strings for acoustics and strings for electrics or does one set do for both

Just started playing hence the (maybe) stupid question

They are a different set of strings

Don't get electric guitar strings

Don't get classical guitar strings

DO get ACOUSTIC guitar strings, it should be labelled clearly on the packet, and just go for the 'normal' tension, as you are just starting out that should be fine!
Electric strings are designed to be "heard" magnetically by the pick-ups of an electric. Acoustic strings are designed to be "heard" acoustically. Since they're both metal, you could use one on the other type of guitar but it prolly won't sound as good as the proper strings.
