Those tiny ones look to be about 6". You want to look for something about 9" or 12". Amazon usually has the LxWxH in the item description which makes it easier. I have these: https://www.amazon.com/gp/product/B07DH8JFS9/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 and they are definitely adult sized.
