Pattern clothes sizes questions

Hi.I was wondering if a person could change a pattern measurements or the pattern or gauge like a sweater to t a larger woman?could a person do that with any pattern like change it to match your larger size or sizes to fit you?.
Thanks. I 'd like your guys thoughts or opinions on this .

Yes, if you know the measurements. The problem may be you have to knit the item to know what about it doesn’t fit.

I think it depends on the pattern, the size difference and your experience. If you only want to go up a size you might be able to just use a larger needle and or heavier yarn. If you need a multiple size difference you might be able to adjust the numbers, but there will be some experimenting. What is the pattern you’d like to knit? A name and link would helpful. (Don’t post the pattern itself here)
