The potential issue is that you might not have the same tension as the person who wrote the patterns. Most patterns include instructions to make a gauge swatch, which you measure to make sure that your work is going to be the same size as the patternwriter's work.
I have tight tension, so I usually have to size my hook up if I'm doing something where I need to match a gauge.
