Riding the train

My name may be Flat Stanley, but in Holland I also feel like Short and Small Stanley. Here is a picture of me riding in the train to Utrecht. Look at me in this giant chair.

Everybody seems so tall here, both ladies and gentlemen. I have seen the biggest castle, the tallest bridge and perhaps the tallest people in the world.

Help me:
Am I so small or are Dutch people really tall?
