How do I know which instruments might be best for me

Our teacher's will help guide you in your decision as there are a number of different factors to be taken into account:        

How big are you? String instruments come in different sizes so there will always be one that is the correct size for you but woodwind and brass instruments do not, so you need to have grown sufficiently to be able to hold these instruments.

Do you like to be the centre of attention? If so you will be happy on an instrument that is often the centre of attention such as the violin, cello', flute, clarinet, oboe, saxophone, trumpet, cornet.  If you are a little shy then an instrument such as the viola, guitar or tenor baritone might suit you.

Do you want to play an instrument that not so many choose?   If so think about the viola, double bass, oboe, bassoon, trombone, french horn.

Also remember that you may change instrument at a later stage eg. when you have grown a bit more or when a different choice becomes available or because your teacher has recommended a change.  Tuition on the first instrument will have helped to develop your listening and co-ordination skills as well as your music reading skills and these will all help if you do decide to change instrument later.
