The Oni Sellsword is 12 maps (one of them is a testing map) and is only an hour and a half game. Funny enough, only 3 of those maps allow the player to actually walk around and do stuff. Guess I couldn't manage to tell a story without showing the player around the world, heh. If I remember correctly, they are usually around 30x30 in total size (like 50x21, 25x40, 40x40). I only have one map that is tiny, but none of them are "huge". My next game will probably be around 100 maps, looking at the script I have. It's just a question of how much I can use the same locations. In some cases, too, an area that is revisited will need to be different enough to require a new map. I think the sizes will be about the same size as my finished game, too. I'm doing a very linear story where the player essentially plays through traditional "levels" rather than open world exploration. But to answer the question of being "satisfied" with the amount of maps? Well, really just planning. I have a script already written out that determines where the player goes and such, and I fill the maps with content. If anything, I'm cutting content where I think things are getting dragged out. So I'm not really looking at it in terms of trying to figure out an arbitrary quota. I'm just putting out all the ideas I have, getting them to work together and make sense in planning, and then cutting out the worst bits. All in service of a predetermined story and plan.
