Silly question about using two strands

maybe a silly question, but if I use two strands of yarn (instead of one that is called for in the pattern) will my measurements be off? I realize the project would be thicker but what about width/length?
Thanks so much in advance! Love this website!!

Not a silly questions at all! It will be bigger with the extra yarn. I would make a swatch to find out how off the gauge will be. Altho if it is for something like blanket or washcloths gauge really won’t matter.
