Topic tags/keywords: question

I have a question about flipping a square to see if it is square. It seems to me that just flipping it over and making sure it is parallel to the first line wouldn’t really tell the whole story.
I would think that a 2 in square could look good for two inches but lose some accuracy over a distance. If I’m correct about this how far should a square be checked?

I’m not sure what you are getting at here. How could a 2” square be squarer for longer than 2”?

Without knowing whether it’s the correct way, I usually check mine the full length of the blade…for the reasons you mention.

When you are using the two inch square all you can measure is the two inches anyway. I you need to accurately measure beyond the two inches you should probably be using a longer square. All the test you described does is to illustrate the angle is the same 90 degrees for both orientations for that tool.
