Is the adjective order in the sentence below correct?
He is a tall, handsome, educated guy.
That is correct. Size comes before type. Since handsome and educated are both types, their order doesn't matter much. But handsome is pretty close to tall because it's a physical descriptor, so your order is better. Choose a different 'type', and the order doesn't matter so much:
He is a tall, educated, friendly guy.
He is a tall, friendly, educated guy.
