As a general guideline for children, any 3/4 size nylon classical type works best. Smaller children might require a half size instrument but metal strings instruments should be avoided.

For adult players, both nylon and metal string instruments are suitable depending on your style of music: metal strings for pop/rock, nylon for classical and pop. Nylon strings are easier to play for beginners but metal strings produce a fuller sound. Full size is usually suitable for most adults.

 How much should I spend on a guitar?

Obviously, the more expensive the instrument, the better the quality. I always advise parents to invest no more than £50 on a first instrument. Argos sells a basic quality 3/4 model for £30 including bag. Most music shops offer several models in the £35-£50 bracket or it is worth looking on Ebay.

Some recommended models: Encore, Stagg, Jose Ferrer.

There is much choice for adults in the £40- £100 range. Check on EBay for new models in your price range. Used models can also be considered but avoid any instrument which has been played a lot and produces buzzing sounds.

Recommended models:

Yamaha , Fender, Ibanez, Tanglewood, Takamine.
