I didn't have a ruler at the time, and I packed the turbo up. I should have had a reference like a penny or something, but I was wondering if there were any ways to tell what size the compressor wheel is.

You'll have to measure it, with some accurate vernier calipers or a micrometer. I don't think there is any way to tell, just by looking at it.

Then compare the readings to the charts, and match it up:
