would it be fair to say the the smaller one is +- 5cm and the bigger about 12cm???

Morning Shawn, the correct way to measure a T is from one front leg to the opposite back leg. Look at the photo in this post. That is the best way of measuring. Add a couple of mm's if one or both legs are pulled up a bit.

Hope this helps

that does help. thanks phantom. i was measuring them across like wingspan but i see they should be measured from front to back. makes more sense and makes measuring easier.
