Kobold Size? (Patreon)

What's everyone's opinion on scale for the kobold?

The middle kobold is what I have it at now, but in DnD the height of a kobold is around 2 1/2 feet (right version).

Of course you have your pros and cons with this. That small is correct size, but harder to print. I know you can resize it to your liking, but I like to release things as final as possible.
