Even 2 rulers made by the same company can be different, as well as 1 ruler when it's new and the same ruler when it's 5 years old. There can be slight slippage during manufacture that gets past quality control. You may "shave" the edge of your ruler each time you cut, thus changing it's measure with age. There is also a difference if you cut through several layers of fabric or 1 layer. Ever wonder why the same size clothes from the same brand fit differently? It's the fact that several layers of fabric compress. The top will normally be very slightly larger, even more so as your blade dulls. Learned this in design school 50 years ago. Oh, I still use multiple rulers, and my cutting mat!

Hmmm--guess I'd better get off the board and go do a ruler check. No doubt, if I messed up, I'd figure it was my error and never associate the problem with using different ruler brands. Thanks for the heads up on this.

When we tried the same brand square-up ruler as the 18" one, my square was right on the size! Amazing! :roll: :-D

It is always interesting to see what I can learn here on this board! It is good to be reminded of what I know! I hear this in all my classes--to stick with the same ruler throughout and the same machine!
