How it works
Two long walls and two short walls each take the height times their length, and the roof takes the length times the width. Add them together for the total mesh area.
Doors, windows and overlaps at the seams need a little extra, so add a margin before you buy.
Worked example
A catio 8 ft long, 4 ft wide and 6 ft high needs about 176 ft² of mesh for its walls and roof.
Questions
Does this count the floor?
No. Most catios sit on the ground or a deck, so the floor is not counted. Add it yourself if you plan to cover it.
How much extra mesh should I buy?
Add a little for overlaps, doors and cuts. A small margin keeps you from running short partway through.
Does this check that the enclosure is secure?
No. It only adds up the area. Check the mesh size, fixings and door latches yourself.
