Graydahk is about 26 inches tall, if memory serves. With Czar's latest modifications, he may be even taller now.

That makes him, if scaled to the Inika: 21 feet tall, if scaled to the Toa Metru: 26 feet tall, and if scaled to the Toa Nuva/Mata: 30 feet tall.

If you scale him to Heroscape figures, he's about 120 feet tall. I was bored and decided to figure that out one day, using Argh's figurines. I have no Heroscape, in case you were wondering.
