From what I’ve seen on the wiki and posts about the different farm types, the Meadow Farm has a total of 4,207 usable tiles, with 2,066 for crops and 2,141 that you can build on but not farm
So it’s actually the second biggest farm in the game, only behind the Beach Farm with 4,628 tiles, and bigger than the Standard Farm which has 3,662 tiles
That’s why I think it’s pretty underrated, because it’s not just for animals, you can also grow a lot of crops there
And if you also consider not just the space but the fact that in other farms blue grass is a late-game item, plus you start with a coop and two chickens, and you also begin with a dresser that lets you store clothes and rings without taking up chest space, which usually takes a while to get on other farms, and on top of that you can fish there too, when you take all of that into account it ends up being one of the best farms in the game
