This Kovu plush I recently purchased from one of my close friend ~amurtigress from Germany. He purchased it at the Disneystore in Frankfurt, Germany back around the time Simba's Pride was released. The Disneystore in Frankfurt has since closed. Kovu is 16" tall, 8" wide and 10" deep excluding his 8" tail.
I've been looking at your gallery which is really interesting and gives me many pleasant memories, I'm kinda surprised that you don't have any Kovu and Kiara plushs which are the same as mine.[link] <- thats what mine look like. Out of interest, have you seen these ones before?
I have never seen a bigger version of this one. How big is it this one you have? Do you have a photo? The only larger one I know of is the Disneystore sold a larger laying Kovu and Kiara which was like 30" long.
