Thanks for your comment, Suzy!
My height is about 168 - 168.5 cm, it's inbetween 5'6" and 5'7" (there was no option on this website to choose more precisely)
I approached some agencies here in Vienna but i was told that modelling market here is not huge and they only hire models above 175 cm (5'9")tall. So according to local standards i would probably be classed as petite model
But thank you for your link, i will try it!
