To check:
This is one of many examples of using three strips to check to see if you will get close to the expected size

Actually, most of us can only get an approximation of any "exact" measurement due to the measuring tools we have and what we are measuring.
When I am cutting a "2.5 inch strip" with my rotary cutter - it's actually a bit wider than that due to the way I lay my ruler on the fabric and the distance between the edge of my ruler and the rotary cutter.
I think that the reason some pattern writers say "scant 1/4 inch" is so that it is no more than 1/4 inch.
The three strip test method - using the fabric and thread that one is intending to use - is worth the time and effort.
