What's the correct size of a sat dish?

Here we go with a very stupid question?

Few years ago a bought a triax sat dish but I forgot the size of the dish.
The other day I went with the meter and it is 90cm horizontal 100cm vertical.

What is the correct size of the satdish now 90cm or 100cm?

e.g: pic down below?

If it's a Triax it's a TD88, which is a 90cm dish.
