How do you figure out the size of your habitat?

[Imortalin]

I am looking to build a habitat and it needs to be some many meters as per the animal zoopedia. But how do you guys figure out how wide and long the barriers need to be? a tad confused on this aspect of the game. I am doing the career mission where and I need 1 more species to complete the gold star. Thank you...

Maths from school: Area = Length x Width. Now that's just for square/rectangular shaped areas, if you have curved or triangular parts then you'll have less space and not as simple to calculate as just LxW, but not much more to it if you want to get technical.

You can only see the size of a habitat once you put a gate in (then it's shown on the Terrain tab). So I usually guess the size, put a gate in, check the size, and then move the walls as needed. (Click the gate, click "Edit Barrier", click one of the posts between the walls, move it - attached walls will automatically stretch or shrink.)

Sometimes other areas of known size in the vicinity can help to make a better estimation.

Side note: The number shown in the Zoopedia is the minimal space requirement of the traversable area, for one animal. Be aware that you need more than that to make your animals happy. Putting things into the habitat will reduce the traversable area, and every additional animal increases the space requirement a bit. The amount depends on the species - additional turtles require only 5 sqm more, other animals require 100sqm more per animal, etc.

^as above mentioned
Also you might need to leave some extra space due to shelter, terrain, water, future babies also take space then what the Zoopedia sugguests.

Basically I guess and add a little extra. Usually this works fine.
